In order to reduce accidents and enhance the safe operation of mowers, Schulte, in cooperation with other industry

manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower Safety Practices video and guide

book.

The video will familiarize and instruct mower-tractor operators in safe practices when using industrial and agricul-

tural mowing equipment. It is important that Every Mower Operator be educated in the operation of their mowing

equipment and be able to recognize the potential hazards that can occur while operating a mower. This video,

along with the mower operator’s manual and the warning messages on the mower, will significantly assist in this

important education.

Your Authorized Schulte Dealer may have shown this video and presented you a DVD Video when you purchased

your mower. If you or any mower operator have not seen this video, Watch the Video, Read this Operator’s Man-

ual, and Complete the Video Guidebook before operating your new mower. If you do not understand any of the

instructions included in the video or operator’s manual or if you have any questions concerning safety of operation,

contact your supervisor, dealer or Schulte.

If you would like a VHS video tape of the video, please e-mail [email protected] or Fax AEM VHS

Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to AEM VHS Video 1502

E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please include your name, mailing

address, mower model and serial number.

Every operator should be trained for each price of equipment (Tractor and Mower), Understand the intended use,

and the potential hazards before operating the equipment.

The information and material listed above along with this Operator’s Manual can assist you in meeting the OSHA

requirement for Operator annual training.

OSHA TRAINING REQUIREMENTS

The following training requirements have been taken from Title 29, Code of Federal Regulations Part

1928.57 (a)(6). www.osha.gov

Operator Instructions. At the time of initial assignment and at least annually thereafter, the employer shall instruct

every employee who operates an agricultural tractor or implement in the safe operating practices and servicing of

To the Owner/Operator/Dealer

This Operator's Manual is an integral part of the safe operation of this machine and must be maintained with the

implement at all times. A Manual canister is provided on the implement where this manual can be properly stored.

If you lose or damage this manual a free replacement manual can be obtained from an authorized Schulte dealer or

by down loading the manual from the Schulte website www.schulte.ca

BEFORE YOU START! READ, UNDERSTAND, and FOLLOW the information provided in this manual, the AEM

Mower Safety manual and the tractor operator's manual carefully to learn how to operate and service your machine

properly. Failure to do so could result in personal injury to you and bystanders. All implements with moving parts

are potentially hazardous. Every effort has been made to ensure that the machine is safe but operators must avoid

engaging in unsafe practices and follow the written instructions provided. The manufacturer has designed this

implement to be used with all its safety equipment properly attached to minimize the chance of accidents.

The care you give your Schulte Implement will greatly determine your satisfaction with its performance and its

service life. Carefully read and follow the instructions in this manual to provide you with a thorough understanding

of your new implement and its intended use and service requirements.

All references made in this manual to right, left, front, rear, top or bottom are as viewed facing the direction of

forward travel with the implement properly attached to the tractor.

Replacement Parts information is located in a separate Parts Manual. Schulte mowers use balanced and matched

system components for blade carriers, blades, cuttershafts, knives, knife hangers, rollers, drivetrain components,

and bearings. These parts are made and tested to Schulte specifications. Non-genuine “will fit” parts do not

consistently meet these specifications. The use of “will fit” parts may reduce mower performance, void warranties,

and present a safety hazard. Use genuine Schulte mower parts for economy and safety.

For future reference, record your Schulte product model number and serial number

•REPAIR OR REPLACE if damage, broken or missing

•ALWAYS REPLACE GUARDS that have been removed for service or maintenance.

• Do Not use PTO or PTO guard as a step.

TO AVOID broken driveline during operations:

•CHECK driveline for proper length between PTO shaft and implement gearbox shaft.(Refer to Instructions

in Operation Section)

• Drivelines too short can pull apart or disengage.

• Drivelines too long can bottom out.

• Bottoming driveline telescoping assembly will stop sliding and become solid.

• Driveline bottoming can push through support bearings and break off PTO shaft

•AVOID sharp turns or lift mower to heights to cause driveline "knocking".

• Lubricate driveshaft-telescoping components weekly.

CONTACT DEALER if implement driveline does not match Tractor PTO shaft:

•DO NOT USE PTO ADAPTER.

Using a PTO adapter can cause excessive vibration, thrown objects, blade and implement failures by doubling

operating speed. Increased working length exposing unshielded driveline areas. PN PE01str

FEDERAL LAWS AND REGULATIONS

This section is intended to explain in broad terms the concept and effect of federal laws and regulations con-

cerning employer and employee equipment operators. This section is not intended as a legal interpretation of

the law and should not be considered as such.

Employer-Employee Operator Regulations

U.S. Public Law 91-596 (The Williams-Steiger Occupational and Health Act of 1970) OSHA

This Act Seeks:

“...to assure so far as possible every working man and woman in the nation safe and healthful working

We are pleased to have you as a Schulte customer. Your Rotary Cutter has been carefully designed with care

and built with quality materials by skilled workers to give maximum service with minimum down time. This

manual is provided to give you the necessary operating and maintenance instructions for keeping your rotary

cutter in top operating condition. Careful use and timely service saves extensive repairs and costly downtime

losses. Please read this manual thoroughly. Understand what each control is for and how to use it.

Schulte typically offers three types of shielding to protect the operator, passerby, livestock, and property from

thrown objects... deflectors, single chain guards, and double chainguards. Shielding should be selected based

on the intended use of the mower. Double chainguards or deflectors should be used for highway, right-of-way,

parks or greenbelt mowing or all other mowing where human dwellings, vehicles, or livestock could be within

300 feet of the mower. Chainguards are more durable, provide a longer service life and require less

maintenance and replacement than deflectors. Single chainguards may be sufficient for agriculture and other

mower use only where passersby or property are not within 300 feet of the mower during operation.

No shielding is 100% effective in preventing thrown objects. The possibility of injury and property damage from

this hazard can be substantially reduce by selecting proper shielding, maintaining the mower and shielding in

good operational condition, inspecting the area for foreign debris before mowing, operating the mower at a

minimum cutting height of 4", and keep unprotected persons at a minimum distance of 300 feet from the

mower at all times during operation.

Safety is of primary importance to the owner/operator and to the manufacturer. Observe all safety precautions

decaled on the machine and noted throughout the manual for safe operation of implement. If any assistance or

additional information is needed, contact your authorized Schulte dealer. The owner/operator/dealer should

know and understand the Safety Messages before assembly and be aware of the hazards of operating this

cutter during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen

below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced

when operating this machine.

Indicates a hazardous situation that, if not avoided, WILL result in DEATH OR VERY

SERIOUS INJURY.

Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH

OR SERIOUS INJURY.

Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR

INJURY.

Identifies special instructions or procedures that, if not strictly observed, could result in

damage to, or destruction of the machine, attachments or the environment.

Connect the Flex Arm to a Tractor

Use extreme caution when connecting the implement to the tractor. The implement should be securely resting

at ground level or on blocks. Keep hands and feet out from under the implement and clear of pinch points

between the tractor and implement.

Always shut the tractor completely down, place the transmission in park, and set the parking

brake before you or anyone else attempts to connect or disconnect the implement and tractor

hitches.

1. Ensure the tractor is equipped with the correct

PTO shaft and the drawbar is set at the

correct length. Adjust the drawbar length as

recommended for 540 or 1000 RPM operation

2. Adjust the height of the hitch clevis by

removing and reinstalling the ¾ X 6 bolts so

that the frame is as level as possible.

3. Adjust the opening of the precision clevis by

shimming the wear plate with spacers.

Remove the two 5/8” bolts and lockwashers

and stack the spacers between the wear plate

and the hitch block until the opening

measures less than 1/8” taller than the

drawbar. Replace unused spacers under the

hitch block and reinstall the lockwashers and

bolts.

4. Using the parking jack, position the tongue

clevis to the height of the tractor drawbar. A

screw driver may be inserted into the hole in

the side of the swivel hitch to keep the hitch

clevis level while connecting to the tractor

drawbar.

5. Board the tractor and start the engine. Back

the tractor to the cutter aligning the drawbar

hitch hole with the cutter tongue clevis. Turn

off the tractor engine, place the tractor in park,

and set the parking brake before dismounting.

6. To attach the FLEX-ARM insert the hitch pin

through the drawbar and tongue clevis. Once

the pin is inserted, attach the snap ring pin

through the hole on the hitch pin and snap in

place.

7. Securely attach the cutter safety chain to the tractor drawbar or drawbar support frame. Follow the detailed

instructions below.

8. Lower the jack until the tongue is completely supported by the drawbar. Remove the hitch jack and return it

to the storage position on the castor frame.

Never use your hands to steady the hitch block when the tractor is being backed to hitch

Never stand between the tractor and implement while the tractor is being backed to the hitch

Safety Tow Chain

If the unit is to be towed on a public roadway, a

safety chain with tensile strength equal to or

greater than the gross weight of the cutter must

be connected between the tractor and cutter. This

will help control the implement in the event the

tongue becomes disconnected from the drawbar.

Connect the safety tow chain between the FLEX-

ARM and tractor. Fasten the large loop of the

safety chain to the hitch, using the 1” bolt, washer,

and nut. Attach the other end of the chain to

tractor. Refer to your tractor operator’s manual for

complete instructions on attaching the tow chain

to the tractor. After connecting both ends of the

safety chain, drive the tractor to the right and left

to check for proper chain length. Adjust length as

necessary and allow only enough slack in the

chain to make a maximum turn in both directions.

Lock the Caster Wheels

Pull the frame forward so that the castors are

parallel with the direction of travel. Lock the castor

wheels by inserting a 3/4 X 2-1/2 bolt with 3/4”

locknut into each hole on the castor frame ‘G’.

Bolts and nuts are found in the operator’s manual

canister or in there storage hole near the castor

pivot. The holes to lock the casters in place will

only line up when the stop plates are assembled

to the lock-up tubes. These stop plates reduce

how far the Flex-Arm extends to the left of the

center of the towing vehicle to 54”. When the

plates are not installed, they are located in their

storage location at the rear of the machine.

When the stop plates are installed, the Flex-Arm

does not allow for the center line of the rotary

cutter to be pulled directly behind the tractor. If

you want to cut directly behind the tractor, remove

the stop plates and install them in their storage

location.

IMPORTANT: The castor wheel locking bolts must never be used when the FLEX-ARM is attached to a rotary

cutter. The purpose of these bolts is to lock the castor wheels in a forward direction for moving or transporting

the FLEX-ARM alone.

2.3 Tractor Horsepower

The horsepower required to operate the mower depends on several operating factors including the vegetation

to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most

mowing conditions, the Eagle 10 mower requires a tractor with a minimum of 40 HP and the Eagle15 mower

requires a tractor with a minimum of 50 HP. Operating the mower with a tractor that does not have adequate

power may damage the tractor engine. Exceeding 100 HP for a 540 RPM drive and 140 HP for a 1000 RPM

drive may cause mower damage by overpowering the unit in heavy cutting conditions.

2.4 Drawbar

Position the length of the drawbar from the end of

the tractor PTO shaft to the drawbar hitch hole

according to the operating speed of the mower. If

the mower is a 540 RPM unit, position the drawbar

length from shaft end to hitch hole at 14”. For 1000

RPM mowers, set the drawbar length at 16” for 21

spline 1-3/8” mowers and at 20” for 1-3/4” 20 spline

mowers

2.5 Tractor Hydraulics

The mower deck and wings are raised and lowered with hydraulic cylinders operated by the tractor hydraulic

pump. There are several ways to configure the mower hydraulics depending on the number of tractor selective

control valves and if they are four double acting. The mower can be operated on a tractor with a minimum of

four single acting circuits. One double acting and two single acting cylinders or a three spool control valve must

be used to operate the mower equipped with hydraulic phasing cylinders.

Refer to the assembly and parts section of this manual for hydraulic system set-up or contact an authorized

dealer for the best configuration depending on your tractor hydraulic capabilities and your intended mower use

2.6 Front End Weight

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end

weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front

end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and

weight carriers can be purchased through an authorized tractor dealership. OPS-U-0005 str

OPERATION

@ 2022 Alamo Group Inc.

2.7 Power Take Off (PTO)

Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors

operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower

and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those

operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 20 or 21-spline

shaft. Note: Refer to the tractor owner’s manual for instructions to change PTO speeds on models that

operate at more than one speed.

If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over-

running clutch must be used between the PTO output shaft and the driveline of the mower. An authorized

tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006_A str

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor PTO.

Use of an adapter can double the operating speed of the Implement resulting in excessive

vibration, thrown objects, and blade and implement failure. Adapter use will also change the

working length of the driveline exposing unshielded driveline areas. Serious bodily injury and/

or equipment failure can result from using a PTO adapter. Consult an authorized dealer for

assistance if the Implement driveline does not match the Tractor PTO. (S3PT-14) str

Never operate the Tractor and Mower if the Implement input driveline is directly connected to

the Tractor transmission. Tractor braking distances can be substantially increased by the

momentum of the rotating Mower blades driving the Tractor transmission even though the

Tractor clutch has been disengaged. Install an over running clutch between the Tractor PTO

and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16) str

2.8 Tire Spacing

The tire spacing of the tractor must be sufficient to

maintain stability on the type of terrain where it is intended

to be operated and for the type of implement that is being

operated. Always refer to the tractor Operator’s Manual or

consult the tractor’s authorized dealer for instructions on

sufficient tire spacing or to change tractor tire spacing.

Operating without sufficient tire spacing to maintain

stability can result in loss of control of the tractor, a rollover

accident, or death or serious injury.

Operate this Equipment only with a Tractor equipped with

an approved roll-over-protective system (ROPS). Always

wear a seat belt. Death or serious injury can result from

falling off the tractor and/or becoming pinned or trapped

under the tractor or implement particularly during a

rollover accident.

3.GETTING ON AND OFF THE TRACTOR

Before getting onto the tractor, the operator must read and completely understand the implement and tractor

operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a

complete explanation. OPS-U- 0007str

Do not mount or dismount the Tractor while the tractor is moving. Mount the

Tractor only when the Tractor and all moving parts are completely stopped.

Dismounting a moving power unit can result in a crushing hazard that can

cause death or serious injury. (SG-12) str

3.1 Boarding the Tractor

Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control

levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt

around you.

Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be seriously

injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra riders at

all times. OPS-U- 0008str

Never allow children to operate, ride on, or come close to the Tractor or

Implement. Usually, 16-17 year-old children who are mature and

responsible can operate the implement with adult supervision, if they have

read and understand the Operator’s Manuals, been trained in proper

operation of the tractor and Implement, and are physically large enough

to reach and operate the controls easily. (SG-11) str

Never allow children or other persons to ride on the Tractor or Implement.

Falling off can result in death or serious injury. (SG-10)str

3.2 Dismounting the Tractor

Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake, idle

the engine down, disengage the PTO, and lower the implement to the ground. Shut down the tractor engine

according to the operator’s manual, remove the key, and wait for all motion to completely stop. Never leave

the seat until the tractor, its engine and all moving parts have come to a complete stop.

Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud,

ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support

and never rush or jump off the tractor. OPS-U- 0009 str

caution when mud, ice, snow or other matter has accumulated on the steps or hand rails. Use all hand rails and

steps for support and never rush or jump off the tractor.

4.STARTING THE TRACTOR

The operator must have a complete understanding of the placement, function, and operational use of all tractor

controls before starting the tractor. Review the tractor operator’s manual and consult an authorized dealer for

tractor operation instructions if needed.

Essential Tractor Controls:

• Locate the light control switch.

• Locate the engine shut off control.

• Locate the brake pedals and the clutch.

• Locate the PTO control.

• Locate the 3-point hitch control lever.

• Locate the hydraulic remote control levers

Before starting the tractor ensure the following:

• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.

• Make sure all guards, shields, and other safety devices are securely in place.

• The parking brake is on.

• The PTO control lever is disengaged.

• The 3-point hitch control lever is in the lowered position.

• The hydraulic remote control levers are in the neutral position.

• The tractor transmission levers are in park or neutral.

Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and

belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.

After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden and

unexpected tractor movement. OPS-U-0028str

Never run the Tractor engine in a closed building or without adequate ventilation. The

exhaust fumes can be hazardous to your health. (SG-23) str

Start tractor only when properly seated in the Tractor seat. Starting a tractor in

5.CONNECTING THE FLEX-ARM TO THE TRACTOR

Refer to the ASSEMBLY SECTION of this manual for information regarding connection of the FLEX-ARM to

the rotary cutter.

5.1 Connecting Mower Hydraulic Lines to the Tractor

With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the

control levers back and forth several times or placing the levers in the float position. Keep mower hydraulic

lines, hoses, quick couplers, and swivels free of contamination. Never leave a disconnected hose end open

and cap the tractor hydraulic outlet ports when not in use. If the tractor ports or cutter hydraulic hose ends

become contaminated, wipe clean with a rag before connecting.

Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and

fuel are explosive and their presence could present a hazard. Do not

check for leaks with your hand! High-pressure oil streams from breaks in

the line could penetrate the skin and cause tissue damage including

gangrene. To check for a hose leak, SHUT the unit ENGINE OFF and

remove all hydraulic pressure. Wear oil impenetrable gloves, safety

glasses and use cardboard to check for evidence of oil leaks. If you

suspect a leak, REMOVE the HOSE and have it tested at a Dealer. If oil

does penetrate the skin, have the injury treated immediately by a

physician knowledgeable and skilled in this procedure. (SG-15) str

LX-1510 Hydraulic Circuit Requirements, 15’ Requirements

Hoses and breakaways are provided in order to connect to a 15’ rotary cutter with individual single acting wing

circuits. A total of 4 hydraulic circuits are required. Two of the circuits require float positions on the control

valves in order to operate the single acting wing circuits on the rotary cutter.

FLX-1510 Hydraulic Circuit Requirements, 10’ Requirements

Hoses and breakaways are provided in order to connect to a 10’ rotary cutter with single acting wing circuit. A

total of 3 hydraulic circuits are required. One of the circuits requires a float position on the control valve in order

to operate the single acting wing circuit of the rotary cutter.

Hydraulic Line Support

After connecting the Flex-Arm hydraulic lines to the tractor, and mower hydraulics to the Flex-Arm, support the

hoses with the equipped brackets. Ensure that hoses do not contact the driveline, do not bind while turning,

and do not become pinched or kinked.

Hydraulic Cylinder Priming

Hydraulic Cylinders must be filled with hydraulic oil before removing the wing transport pins to lower the mower

wings and deck. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position

until the cylinders fully retract (wing cylinders) and extend (center cylinder). Place control levers in the float

position and repeat process several more times to purge all air from the system. Ensure wings are entirely

supported by the cylinders before removing the transport pins. NEVER drive out pins and NEVER remove

transport pins that have tension on them.

6. SETTING THE MOWER

Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make

a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of

uneven terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most

damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may

cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height

which causes the blades to contact the ground. OPS-U- 0010 str

Never work under the Implement, the framework, or any lifted

component unless the Implement is securely supported or blocked up

to prevent sudden or inadvertent falling which could cause death or

serious injury. (SG-14)str

6.1 Setting Deck Height

The cut height for the center section is set by

extending or shortening the depth collar located on

the center lift cylinder. Cutting height for the wing

cylinders will be automatically controlled by the

hydraulic phasing system. Depth stops are also

provided on the wing cylinders as back up for fine

adjustments.

IMPORTANT: If depth control stops are not set at

the same height as the center cylinder, internal

damage may occur to the phasing cylinders.

The cutter should always be operated in the highest

position that will produce the desired cutting

results. Operating at increased heights will

minimize the chances of blades contacting the

ground and discharging debris.

6.2 Setting Deck Pitch

Mower should be operated with the deck

approximately 3/4" HIGHER IN THE FRONT

THAN THE REAR.

Operating the mower at this pitch will allow the

mower to cut the grass twice and can result in a

more even cut and improved distribution of the

cut material.

IMPORTANT: Adjust the leveling rods the same

amount and maintain equal tension in the rods.

Improper adjustment may cause rods to snap or

bend. Re-tighten the jamnuts after the deck pitch

has been set

NOTE: Adjusting the cutter deck higher at the

front can help reduce scalping.

7.DRIVELINE ATTACHMENT

The driveline yoke and tractor PTO shaft must be

dirt free and greased for attachment. To connect

the CV (constant velocity) driveline to the tractor

PTO output shaft, twist driveline yoke collar and

align the grooves and splines of the yoke with

those of the PTO shaft. Push the driveline yoke

onto the PTO shaft, release the locking collar, and

position the yoke until the locking collar balls are

seated onto the PTO shaft. Push and pull the

driveline back and forth several times to ensure a

secure attachment..

IMPORTANT: DO NOT use a non-CV tractor

shaft. Driveline damage will occur when turning

the implement.

When attaching the PTO yoke to the Tractor PTO shaft, it is important that the spring

activated locking collar slides freely and the locking balls are seated securely in the groove of

the PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could slip off and

result in personal injury and damage to the cutter.

7.1 Constant Velocity (CV) Driveline

For mowers equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor

and mower must be determined to ensure the joint angle does not over-extend which can cause CV joint

damage. Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at

angles up to 70°. Angles greater than 80° can result in mechanical damage to the CV joint and mower

driveline

The Constant Velocity joint must be lubricated every 8 hours of operation as specified in the Maintenance

Section. Failure to properly lubricate the joint will result in accelerated wear and joint component failure.

CV Driveline Maximum Angle Check Procedure

With the mower attached to the tractor and the driveline disconnected from the tractor PTO stub make a

hard left turn until there is approximately a 1" clearance between the left rear tractor tire and mower frame or

tongue.

Stop and completely shut down the tractor. Place the tractor in Park and apply the Parking Brake before

dismounting.

Check the CV joint at this maximum turning radius by holding the driveline yoke above the PTO shaft and then

angle the CV joint to its maximum angle. A minimum difference of 10 degrees between the center line of the

yoke and the PTO shaft must be maintained to ensure the joint will not be over angled. If the joint cannot be

angled at least 10°, there is a potential problem of over-angling the joint while making sharp turns.

Solutions: To ensure the joint is not damaged, check the following:

Check the drawbar length to ensure that it is at the proper length for the RPM speed of the mower.

Move the tractor rear tires wider apart to limit the tractor turning radius.

OPERATION

FLX-1510 08/22 Operation Section 4-12

OPERATION

@ 2022 Alamo Group Inc.

Position the mower at multiple angles and perform the above procedure. Determine the sharpest turning

radius that maintains a safe operating angle and note this position to the operator. OPS-R-0006 str

Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline

which will cause accelerated wear and breakage of drive train components and could result

in possible injury from the separated Driveline sections. (SRM-04) str

8. PRE-OPERATION INSPECTION AND SERVICE

Before each use, a pre-operation inspection and service of the implement and tractor must be performed. This

includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and

functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection reveals

any condition affecting safe operation. Perform repairs and replacement of damaged and missing parts as

soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time and

repair cost can be avoided. OPS-U-0029str

Always disconnect the main PTO Driveline from the Tractor before performing service on the

Implement. Never work on the Implement with the tractor PTO driveline connected and

running. Rotating Parts, Blades or Drivelines could turn without warning and cause

immediate entanglement, injury or death. (S3PT-11)str

DO NOT allow any person under a folded wing unless wing is securely

locked up or supported. DO NOT approach the Implement unless the

Tractor is turned off and all motion has ceased. Never work under the frame

work, or any lifted component unless the implement is securely supported

or blocked up. A sudden or inadvertent fall by any of these components

could cause serious injury or even death. (STI-03) str

Periodically inspect all moving parts for wear and replace when necessary

with authorized service parts. Look for loose fasteners, worn or broken

parts, and leaky or loose fittings. Make sure all pins have cotter pins and

washers. Serious injury may occur from not maintaining this machine in

good working order. (SG-21 )str

10. DRIVING THE TRACTOR AND IMPLEMENT

Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and

precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the

weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while

driving the tractor with an attached implement, review the following. OPS-U- 0012str

This Implement may be wider than the Tractor. Be careful when operating or transporting

this equipment to prevent the Implement from running into or striking sign posts, guard rails,

concrete abutments or other solid objects. Such an impact could cause the Implement and

Tractor to pivot violently resulting in loss of steering control, death, or serious injury. Never

allow the Implement to contact obstacles. (S3PT-12)str

Transport only at speeds where you can maintain control of the equipment.

Serious accidents and injuries can result from operating this equipment at

high speeds. Understand the Tractor and Implement and how it handles

before transporting on streets and highways. Make sure the Tractor steering and brakes are

in good condition and operate properly.

Before transporting the Tractor and Implement, determine the proper transport speeds for

you and the equipment. Make sure you abide by the following rules:

Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly

to determine the stopping characteristics of the Tractor and Implement. As you increase the

speed of the Tractor the stopping distance increases. Determine the maximum transport

speed not to exceed 20 mph (30 kph) for transporting this equipment.

Test the equipment at a slow speed in turns. Increase the speed through the turn only after

you determine that the equipment can be operated at a higher speed. Use extreme care and

reduce your speed when turning sharply to prevent the tractor and implement from turning

over. Determine the maximum turning speed for you and this equipment before operating on

roads or uneven ground.

Only transport the Tractor and Implement at the speeds which allow you to properly control

the equipment.

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes

or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance

increases: use extreme care and reduce your speed. When operating in traffic always use

the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you

and watch out for the other guy. (SG-19)str

OPERATION

FLX-1510 08/22 Operation Section 4-23

OPERATION

@ 2022 Alamo Group Inc.

10.1 Starting the Tractor

The procedure to start the tractor is model specific.

Refer to the tractor operator’s manual for starting

procedures for your particular tractor. Consult an

authorized dealer if the starting procedure is

unclear. Ensure the 3-point control lever is in the

lowered position and the PTO is disengaged

before starting the tractor. OPS-U-0033str

10.2 Brake and Differential Lock Set-

ting

Make sure the tractor brakes are in good

operating condition. Tractor brakes can be set to

operate independently allowing single rear wheel

braking action or locked together to provide

simultaneous rear wheel braking. FOR MOST

DRIVING AND OPERATING CONDITIONS, THE

BRAKE PEDALS SHOULD BE LOCKED

TOGETHER TO PROVIDE THE MOST

EFFECTIVE BRAKING ACTION.

Always disengage the tractor differential lock

when turning. When engaged the differential lock

will prevent or limit the tractor from turning. During

normal cutting conditions, locking the differential

provides no benefit and should not be used.

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.

When operating down a hill or on wet or rain slick roads, the braking distance increases. Use

extreme care and reduce your speed in these conditions. When operating in traffic, always

use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around

you and watch out for the other guy. OPS-U- 0013 str

10.3 Operating the Mower Wings

Wings are positioned with hydraulic cylinders. Ensure the hydraulic cylinders and lines are filled with oil by

holding the valve control levers in the raised position until the cylinders fully retract (wings) and extend (center).

Only operate the mower with both wings fully lowered, NEVER operate the mo strwer with a raised wing. Wait

until the blades are at a complete stop before raising wings. OPS-FLX-0006

OPERATION

OPERATION

@ 2022 Alamo Group Inc.

10.4 Transport Position

To raise mower wings, drive the unit to a level area.

DO NOT raise the wings with the rotary cutter

positioned on an embankment. Prepare the FLEX-

ARM and rotary cutter for road transport as follows

• Retract the rotary cutter’s lift and wing lift

hydraulic cylinders

• Retract the FLEX-ARM hydraulic cylinder

• Install the transport pin for the FLEX-ARM

hydraulic cylinder

• Install transport pins for the rotary cutter center

section and wings. Refer to your rotary cutter

operator’s manual for location of the transport

pins.

When the Wings are folded for transport, the center of gravity is raised and the possibility of

overturn is increased. Drive slowly and use extreme caution when turning on hillsides.

Overturning the Implement could cause the Implement to overturn the Tractor and vice versa

resulting in serious injury or even death. Never fold wings on a hillside...the Implement or unit

may overturn. (STI-02) str

10.5 Operating Position

To lower the wings, remove the transport lock pins and secure pins at storage location. DO NOT drive out

transport pins that have tension on them. After removing pins, extend wing hydraulic cylinders and fully lower

wings.

Wing hydraulic control valves should be set in the float detent during operation to allow the mower to follow the

contour of uneven terrain and to prevent the wings from creeping up. When extending a wing over a ditch for

mowing, place the control valve lever detents in the center position for greater stability. OPS-FLX-0007 str

Use extreme care when lowering or unfolding the implement’s wings. Make sure no

bystanders are close by or underneath the wings. Allow ample clearance around the

implement when folding or unfolding the wings. Use extreme caution around buildings or

overhead power lines. (S3PT-05) str

10.6 Driving the Tractor, FLEX-ARM and Rotary Cutter

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the

tractor, flex-arm and cutterr. Moving slowly at first will also prevent the tractor from rearing up and loss of

steering control. The tractor should never be operated at speeds that cannot be safely handled or which will

prevent the operator from stopping quickly during an emergency. If the power steering or engine ceases

operating, stop the tractor immediately as the tractor will be difficult to control. OPS-FLX-0008 str

Allow sufficient clearance for the Implement to swing outward while turning. Implements

carried behind the Tractor will swing outside the tire path when making turns. Contacting a

solid object while turning will cause equipment damage and possible injury. (S3PT-20) str

Perform turns with the tractor, FLEX-ARM and

cutter at slow speeds to determine how the tractor

with an attached FLEX-ARM and cutter handles a

turn. When operating the FLEX-ARM and cutter,

the overall working length of the unit is increased.

Allow additional clearance for the FLEX-ARM and

cutter when turning, especially if the wings are

lowered and the FLEX-ARM is extended.

When the FLEX-ARM is in transport position, it will

stick out 70” to the left side of the tractor. This

allows the rotary cutter and FLEXARM to be exactly

centered behind the tractor. Lighting and marking is

provided to indicate the protrusion of the FLEX-

ARM to the left of the roadway. In some cases; for

instance when working on a narrow road or when

the FLEX-ARM is repeatedly extended and

retracted, the amount of stick out to the left of the

tractor may not be desirable because of

consideration for oncoming traffic. In this case stop

blocks can be installed to limit the amount of stick

out to the left of the tractor to 55”. When the stop

block is installed the rotary cutter will trail 19” to the

right of center. Refer to the “ASSEMBLY” section of

this manual for installation instructions. Extra

precaution should be taken to avoid hitting parked

vehicles, sign, road structures, bystanders and

animals due to the overall length and width of the

implements.

Practice steering and maneuvering the tractor, Flex-Arm and mower in an open field or parking lot before

operating the mower. Use extreme care when backing the equipment. The mower will not react to backing in

the same manner as it does when the mower is connected directly to the tractor. Practice backing until you can

safely control the direction and movements of the Flex-Arm and mower. Back up at a slow speeds to ensure

you maintain control and direction of the mower. Use care to make sure the mower is not backed in to a parked

vehicle, sign, road structures, bystanders, or animals. If you do not feel that you can safely operate and back

the equipment combination than obtain further training before operating this Flex-Arm and mower.

10.7 Crossing Ditches and Steep Inclines

When crossing ditches with steep banks or going

up sharp inclines, it is possible that the main

driveline inner profile will penetrate into the outer

housing to its maximum depth until the assembly

becomes solid (driveline is at its extreme shortest

length). This type of abusive operation can cause

serious damage to the tractor and mower drive by

pushing the PTO into the tractor and through the

support bearings or downward onto the PTO

shaft, breaking it off.

Damage resulting from over-collapse of the driveline’s inner profile and its outer housing may

allow the driveline to come loose from the Tractor which could cause bodily injury to the

operator or bystanders and/or extensive damage to the Tractor or Implement.

OPS-R-0020 str

10.8 Correctly Crossing Ditches and Inclines

When confronted with an incline or ditch, do not

approach from an angle which is perpendicular or

straight on as damaged to over collapse of the

driveline may occur.

When crossing such terrain, the implement

should be fully lowered for a lower center of

gravity and added stability. OPS-R-0021 str

OPERATION

FLX-1510 08/22 Operation Section 4-27

OPERATION

@ 2022 Alamo Group Inc.

Inclines and ditches should be approached along

a line which is at an angle as shown. This type of

path will reduce the possibility of over-collapse of

the driveline and resulting damage. If the

gradient is so steep that such an approach

increases the possibility of a tractor roll-over,

select an alternate crossing path.

When operating the tractor and mower across

slopes and inclines, through ditches, and other

uneven terrain conditions, it is important to

maintain sufficient deck to ground clearance.

Blade contact with the ground may cause soil,

rocks and other debris to be thrown out from

under the mower resulting in possible injury and/

or property damage. Ground contact also

produces a severe shock load on the mower drive

and to the mower blades resulting in possible

damage and premature wear. OPS-R-0022 str

11.OPERATING THE TRACTOR, FLEX-ARM AND MOWER

THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR, FLEX-ARM

AND MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and

understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These

manuals must be read and explained to any operator who cannot read. Never allow someone to operate the

implement and tractor without complete operating instructions.

Before starting any operation, the operator must become familiar with the area to be worked in and any

obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special

attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.

OPS-FLX-0011

Extreme care should be taken when operating near loose objects such as

gravel, rocks, wire, and other debris. Inspect the area before mowing.

Foreign objects should be removed from the site to prevent machine

damage and/or bodily injury or even death. Any objects that cannot be

removed must be clearly marked and carefully avoided by the operator.

Stop mowing immediately if blades strike a foreign object. Repair all

damage and make certain rotor or blade carrier is balanced before

resuming mowing. (SGM-05)str

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the

operating parts of the mower head. These items could then swing outside the housing at

greater velocities than the blades. Such a situation is extremely hazardous and could result

in serious injury or even death. Inspect the cutting area for such objects before mowing.

Remove any like object from the site. Never allow the cutting blades to contact such items.

11.1 Foreign Debris Hazards

Before mowing, inspect the area to make sure

there are no foreign objects that the mower blades

could hit or become entangled with. Remove all

foreign objects and debris. If objects are too big to

remove, mark them clearly and be sure to prevent

the mower blades from contacting them

If you hit a solid object or foreign debris, stop the

mower and tractor at once. Immediately idle the

engine speed and disengage the PTO. Wait for all

mower rotating motion to stop, then raise the

mower and move the tractor and implement off the

object. Inspect the area and remove, or mark the

location of the debris. Inspect the condition of the

mower and make any needed repairs immediately.

Make sure the blades are not damaged and the

carrier is balanced before resuming operation.

Always wear your seat belt securely fastened and

only operate the tractor and mower with the ROPS

in the raised position. If the tractor or mower hits a

tree stump, rock, or bump, a sudden movement

could throw you off of the seat and under the

tractor and/or mower. The seat belt is your best

protection from falling off the tractor and the ROPS

provides protection from being crushed during a

tractor roll-over. OPS-R-0023 str

11.2 Bystanders/Passersby Precautions

If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,

idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the

300 foot distance. OPS-R-0024 str

In case of emergency, shut down tractor engine, disengage the PTO and wait for all rotating motion to stop.

Place the tractor in park position, engage the parking brake and remove the key before leaving the operator’s

seat.

OPERATION

@ 2022 Alamo Group Inc.

Rotary Mowers are capable under adverse conditions of throwing

objects for great distances (300 ft (100 m) or more) and causing

serious injury or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 300 Feet (100 m) UNLESS:

- Front and Rear Deflectors, Chain Guards, or Bands are installed and in good,

workable condition;

- Mower sections or Wings are running close to and parallel to the ground without

exposed Blades;

- Passersby are outside the existing thrown-object zone;

- All areas have been thoroughly inspected and all foreign material such as rocks,

cans, glass, and general debris has been removed.

NOTE: Where there are grass and weeds high enough to hide debris that could be

struck by the blades, the area should be: inspected and large debris removed,

mowed at an intermediate height, inspected, closely with any remaining debris

being removed, and mowed again at desired final height. (This will also reduce

power required to mow, reduce wear and tear on the Mower drivetrain, spread cut

material better, reduce streaking, and make the final cut more uniform). (SRM-01) str

11.3 Engaging the Power Take Off (PTO)

Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement

must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with

the implement in the raised position.

Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to

the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear

unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the implement to

determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027 str

Do not let the Blades turn when the Mower Deck is raised for any

reason, including clearance or for turning. Raising the Mower deck

exposes the Cutting Blades which creates a potentially serious hazard

and could cause serious injury or even death from objects thrown from

the Blades. (SRM-07) str

Do not put hands or feet under mower decks. Blade Contact can result

in death or serious injury. Stay away until all motion has stopped and the

decks are securely blocked up. (SGM-09) str

11.4 PTO RPM and Ground Speed

Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.

Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower

at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or

the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground

speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut. If

it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.

Ground speed is achieved by transmission gear selection and not by the engine operating speed. The

operator may be required to experiment with several gear range combinations to determine the best gear and

range which provides the most ideal performance from the mower and most efficient tractor operation. As the

severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to

maintain the proper operating PTO speed. OPS-R-0025 str

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause

Implement driveline or component failures resulting in serious injury or death. (SG-26) str

Mow at the speed that you can safely operate and control the tractor and mower. The correct

mowing speed depends on terrain condition and grass type, density, and height of cut.

Normal ground speed range is from 2 to 5 mph (3-8 kph). Use slow mowing speeds when

operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or

when debris and foreign objects are to be avoided. (SGM-07)str

11.5 Operating the Flex-Arm and Mower

When ready for field use, stop the cutter and pull the transport pins on the cylinder guard and the rotary cutter.

Lower the wings and cutter deck before entering

the ditch. Drive the tractor forward along the side of

the road and extend the Flex-Arm cylinder to ease

the cutter into the ditch. Engage the PTO. Only

operate the FLEX-ARM and cutter from the tractor

operator’s seat with the seatbelt securely fastened.

The tractor must be equipped with a ROPS in the

raised position or a ROPS cab. Before engaging

the PTO the operator needs to make sure that the

blades are rotating in the correct direction. If they

are not, contact your local dealer or Schulte

Industries Ltd to correct the problem. Refer to your

rotary cutter operators manual for proper blade

rotation.

IMPORTANT: The operator should never operate

the cutter and FLEX-ARM if the blades do not have

the proper blade rotation. Serious injury or even

death may occur

OPERATION

FLX-1510 08/22 Operation Section 4-31

OPERATION

@ 2022 Alamo Group Inc.

The rotary cutter and FLEX-ARM combination is designed to cut vegetation up to 2” diameter. Sharp blades

will produce a cleaner cut and require less power. Travel at a speed that allows the cutter sufficient time to cut

through the vegetation and maintain the PTO operating speed to prevent overloading the FLEX-ARM, cutter

and tractor. When cutting along ditch banks, use the arm’s hydraulic cylinder to avoid most obstacles. The

tractor may be needed to maneuver around larger obstacles. The FLX-1510 can swing the cutter 122” using

the cylinder. Choose a driving pattern that provides the maximum pass length and minimizes turning. Under

certain conditions, tractor tires may roll some grasses down resulting in a ragged cut. This is less likely to occur

with the FLEX-ARM since the cutter is outside the path of the tractor tires, however lowering the cut height will

result in a cleaner cut. Avoid mowing in the reverse direction when possible. In situations where the unit must

be backed up to access areas to be cut, make sure there are no people or foreign objects behind the cutter

before reversing. When mowing in reverse, operate the tractor, FLEX-ARM and cutter at a reduced ground

speed to ensure control of the unit is maintained.

Do not mow with two machines in the same area except with Cab tractors with the windows

closed. (SGM-11)str

If a material blockage occurs in the inlet or discharge areas of the mower, SHUT DOWN

TRACTOR ENGINE, disengage the PTO and wait for all rotating motion to stop. Place the

tractor in park position, engage the parking brake and remove the key before leaving the op-

erator’s seat. Clear the blockage before proceeding with mowing. Be sure to keep feet and

hands clear of the mower blades. If you raise the mower or mower wing to access the block-

age, engage the wing lock up latch and securely block up the mower before placing any parts

of the body underneath the mower.

Avoid mowing in reverse direction when possible. Check to make sure there are no

persons behind the mower and use extreme care when maneuvering in reverse. Mow only

at a slow ground speed where you can safely operate and control the tractor and mower.

Never mow an area that you have not inspected and removed debris or foreign material.

(SGM-08) str

Use extreme care when transporting the FLEX-ARM and cutter on public highways and roads. The

combination of FLEX-ARM and cutter is wider than the tractor. In transport position, the FLEX-ARM is offset to

the left of the tractor. Allow ample clearance when transporting the tractor and implements to prevent contact

with bystanders, signs, road structures, or other vehicles. Do not allow the FLEX-ARM and cutter unit to go off

the road shoulder at high speed. This may cause the unit to be unsteady and a roller over may occur, resulting

in serious injury or death.

Follow these guidelines to reduce the risk of equipment and grass

fires while operating, servicing, and repairing the Mower and

Tractor:

• Equip the Tractor with a fire extinguisher in an accesible location.

• Do Not operate the Mower on a Tractor with an underframe exhaust.

• Do Not smoke or have an open flame near the Mower and Tractor.

• Do Not drive into burning debris or freshly burnt areas.

• Ensure slip clutches are properly adjusted to prevent excessive slippage and

plate heating

• Never allow clippings or debris to collect near drivelines, slip clutches, and gear-

boxes. Periodically shut down the Tractor and Mower and clean clippings and

collected debris from the mower deck. (SGM-12) str

OPERATION

FLX-1510 08/22 Operation Section 4-32

Mow only in conditions where you have clear visibility in daylight or with adequate artificial

lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least

300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can

clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,

power lines, debris and foreign objects. If you are unable to clearly see these type of items

discontinue mowing. (SGM-1)str

Never raise the mower entirely while the blades

are turning. If the mower must be raised higher

than 12” from ground level, disengage the tractor

PTO and wait for all mower rotation to come to a

complete stop before proceeding to raise the

mower. NEVER raise the mower wings while the

blades are turning

When turning, the angle between the tractor and

mower should not be so great that a clattering of

the U-joints occurs. Sharp turns can cause

premature failure of the joints and place pressure

on the tractor PTO shaft and could cause

extensive mechanical damage to the mower and

tractor.

Do not let the Blades turn when the Mower Deck is raised for any

reason, including clearance or for turning. Raising the Mower deck

exposes the Cutting Blades which creates a potentially serious hazard

and could cause serious injury or even death from objects thrown from

the Blades. (SRM-07) str

Stay alert and watch for trees, low hanging limbs,

power lines, and other overhead obstacles and

solid ground objects while you are operating.

Use care to avoid hitting these items.

To avoid most obstacles, use the FLEX-ARM

cylinder to steer the cutter. The FLX- 1510 can

swing the cutter 122” using it’s hydraulic cylinder.

The tractor may be needed to maneuver around

larger obstacles.

When mowing across uneven areas such as road shoulders, ditch edges, and other uneven terrain, position

mower so that one support wheel is near the highest point to prevent blades from cutting into gravel or dirt

which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting in rapid wear

or damage to these components. Blades contacting the ground may cause objects to be thrown out from

under the mower deck. Always avoid operating the mower at a height or position which may cause the blades

to contact the ground. Cutting into the berm or edge of the ditch will cause abnormal and accelerated blade

wear and possible blade component failure. OPS-R-0029 str

11.6 Shutting Down the Implement

To shut down attached mower, first bring the tractor to

a complete stop. Then slow down the mower by

reducing the engine speed before disengaging the

PTO. Wait for all rotating motion to stop before

proceeding to drive or shut down the tractor.

Park the tractor on a level surface, place the

transmission in park or neutral and apply the parking

brake, lower the attached implement to the ground,

shut down the engine, remove the key, and wait for all

motion to come to a complete stop before exiting the

tractor. OPS-FLX-0012 str

12. DISCONNECTING THE FLEX-ARM & MOWER FROM THE TRACTOR

Before disconnecting the mower and Flex-Arm, the PTO must be disengaged and blade rotation at a complete

stop. Move the mower to a level storage location and lower the center section and both wings to the ground. If

the mower will be stored with the wings in the raised position, install both wing and center section transport

pins. If the mower is not resting securely on the ground, block the mower up securely before attempting to

disconnect it from the tractor.

Use extreme care to keep feet and hands from under the mower and clear of any pinch points when

disconnecting the mower from the tractor. OPS-FLX-0013 str

Always shut the Tractor completely down, place the transmission in park, and set the parking

brake before you or anyone else attempts to connect or disconnect the Implement and

Tractor hitches. (S3PT-15) str

Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift

the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the

tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue

Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with

possible serious bodily injury or even death. (STI-04) str

When disconnecting the FLEX-ARM and cutter,

the tractor should be completely shut down and

secured in position. Relieve hydraulic pressure by

moving the control levers back and forth several

times.

1. Lower the parking jack and raise the

FLEXARM until the tongue clevis is no longer

resting on the tractor drawbar. Make sure the

jack foot is resting on solid ground or securely

supported by a block before raising the FLEX-

ARM.

2. Once the FLEX-ARM tongue is supported

entirely by the jack, remove the hitch pin.

3. Remove the FLEX-ARM driveline from the

tractor PTO shaft. Place the driveline in its

storage bracket to prevent it from contacting

mud or dirt.

4. Uncouple the hydraulic hoses from the tractor

and secure the on the FLEX-ARM hose

organizer. Disconnect the electrical plug for

the lights and place the plug in its storage

holder on the FLEX-ARM hose organizer.

13. FLEX-ARM AND MOWER STORAGE

Properly preparing and storing the Flex-Arm at the end of the season is critical to maintaining its appearance

and to help ensure years of dependable service. The following are suggested storage procedures:.

Clean any dirt or debris off the mower deck.

• Thoroughly clean all debris off theFlex-Arm and

mower to prevent damage from rotting grass

and standing water.

• Lubricate all Flex-Arm and mower grease points

and fill gearbox oil levels as detailed in the main-

tenance section.

• Tighten all bolts and pins to the recommended

torque.

• Check the Flex-Arm and mower for worn and

damaged parts. Perform repairs and make

replacements immediately so that the flex arm

and mower will be ready for use at the start of

the next season..

• Store the Flex-Arm and mower in a clean, dry

place with the flex arm frame and mower hous-

ing resting securely on blocks or at ground level.

• Keep the driveline yokes from sitting in water,

dirt and other contaminants.

• Use spray touch-up enamel where necessary to

prevent rust and maintain the appearance of the

Flex-Arm and mower.

It is critical that the driveline clutch slip when an obstacle or heavy load is encountered to avoid Flex-Arm,

mower and tractor damage. If the Flex-Arm and mower sit outside for an extended period of time or is exposed

to rain and/or humid air, the clutch lining plates must be inspected to ensure they are not frozen together from

rust or corrosion. If the Flex-Arm and mower have been exposed to such conditions, at the start of each

mowing season, and any time it is suspected that the slip clutch plates may be frozen together, readjust the slip

clutch as detailed in slip clutches of the Maintenance Section in this manual. OPS-R-0098_A str

14.TRANSPORTING THE TRACTOR AND IMPLEMENT

Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind

practices when transporting the tractor and implement between locations. By using good judgment and

following safe transport procedures, the possibility of accidents while moving between locations can be

substantially minimized. OPS-U- 0017str

prevent tipping, especially when traveling through

rough terrain. If the tractor’s hydraulic pump is not

independent of the tractor PTO, or if the tractor PTO

has to be run to have hydraulic power, disconnect

the mower driveline from the tractor PTO output

shaft. Secure the driveline to the mower deck to

prevent driveline damage or loss during transport.

OPS-FLX-0015 str

Before transporting the tractor on a public roadway

or boarding a trailer for transport, the tractor brake

pedals should be locked together. Locking the

such a way as to be clearly visible and legible. When transporting the

Equipment use the Tractor flashing warning lights and follow all local

traffic regulations. (SG-6)str

Extreme caution should be used when transporting the tractor and mower on public roadways. The tractor

must be equipped with all required safety warning features including an SMV emblem and flashing warning

lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive

drivers and most drivers will not be looking out for you, therefore, you must look out for them. Check your side

view mirrors frequently and remember that vehicles will approach quickly because of the tractor’s slower

speed. Be extremely cautious when the piece of equipment that you are towing is wider than the tractor tire

width and/or extends beyond your lane of the road.

Make sure that a proper size safety tow chain is secured between the tractor, Flex-Arm and mower before

entering a public road. Transport the Flex-Arm with cylinder guard transport pin engaged and mower with wing

and center section transport pins engaged. Do not transport the mower supported by hydraulic pressure.

Practice steering and transporting the tractor, Flex-Arm and mower in an open parking lot before transporting

on public roads. Use extreme care when backing the equipment. The mower will not react to backing in the

same manner as it does when the mower is connected directly to the tractor. Practice backing until you can

safely control the direction and movements of Flex-Arm and mower. If you do not feel that you can safely

transport of back the equipment combination, do not transport the equipment on public roads and highways.

Transport at slower speeds that you would normally transport the tractor (70% of normal transport speed).

Allow yourself more time to react, adjust and compensate for the wider equipment. This equipment will trail

behind you like two implements one behind the other. Small turns or sideways movements of the tractor can

cause the trailing mower to move a greater distance to the side.

Use extreme care when transporting the Flex-Arm and mower on public highways and roads. The combination

of Flex-Arm and mower is wide than the tractor. It is also much longer than a single implement attached to the

tractor and you need to allow additional turning clearance. In transport position, the mower is offset at 3’ to the

right of the tractor. Allow ample clearance when transporting the tractor and implements to insure that they do

not contact any bystander, signs, road structures, or other vehicles.

The SMV (Slow-Moving Vehicle) emblem is

universal symbol used to alert drivers of the

presence of equipment traveling on roadways at a

slow speed. SMV signs are a triangular bright

orange with reflective red trim for both easy day

and night visibility. Make sure the SMV sign is

clean and visible from the rear of the unit before

brakes. Ensure that both brake pedals are locked

together when operating on public roads. OPS-U-

0023 str

In the transport position, the Flex-Arm offsets the mower as much as 3’ to the right. Do not allow the trailing

mower wheels to run off the edge of the road or shoulder. Sudden turns or running off the road can cause loss

of stability and possible mower and tractor rollover, resulting in serious bodily injury or even death.

Be particularly careful when transporting the Implement using the tractor. Turn curves or go

up or down hills only at a low speed and at a gradual steering angle. Make certain that at

least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down

on rough or uneven surfaces. (STI-01) str

Only tow the Implement behind a properly sized and equipped Tractor which

exceeds the weight of the Implement by at least 20%. DO NOT tow the

Implement behind a truck or other type of vehicle. Never tow the Implement

and another Implement connected in tandem. Never tow the Implement at

speeds over 20 MPH. (STI-06)str

Secure the Implement for transport before traveling on public roads. For pull-type

Implements, secure the center axle using cylinder stops or transport pin and properly attach

a safety chain between the Implement and Tractor. Secure wings in upright position on

folding Implements using wing transport locks. (STI-7) str

When transporting the implements reduce speed when going around corners. Do not make any sudden turns

at a high transport speed. The tractors and implements are much longer so turning speed needs to be at a low

speed, and more clearance need to be taken in account for when turning.
