In order to reduce accidents and enhance the safe operation of mowers, Bush Hog, 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

agricultural 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 Bush Hog 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 Manual, 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 Bush Hog.

If you would like a VHS video tape of the video, please email A[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 piece 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.

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.

SAFETY FIRST. Completely read and understand the safety section of this manual before operating this

equipment. Do not allow anyone to operate this equipment who has not fully read and understood this manual.

Contact your Dealer to explain any instructions that you do not fully understand.

The care you give your Bush Hog 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. Bush Hog 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 Bush Hog 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 Bush Hog mower parts for economy and safety.

General Safety Instructions and Practices

A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to

the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and

observing certain precautions. The first section of this manual includes a list of Safety Messages that, if

followed, will help protect the operator and bystanders from injury or death. Read and understand these Safety

Messages before assembling, operating or servicing this Implement. This equipment should only be operated

by those persons who have read the manual, who are responsible and trained, and who know how to do so

responsibly.

The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this

manual and on decals which are attached to the equipment. The Safety Alert Symbol means:

“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word

are intended to warn the owner/operator of impending hazards and the degree of possible injury

faced when operating this equipment.

Indicates an imminently 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.

NOTE: Identifies points of particular interest for more efficient and convenient operation or repair.(SG-1)

Practice all usual and customary safe working precautions and above all---remember safety is

up to YOU. Only YOU can prevent serious injury or death from unsafe practices.

READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or

death may occur unless care is taken to follow the warnings and instructions stated in the

Safety Messages. Always use good common sense to avoid hazards. (SG-2)

completely understand this Manual, the Tractor Operator’s Manual, and

each of the Safety Messages found in the Manual or on the Tractor and

Implement. Learn how to stop the tractor engine suddenly in an

emergency. Never allow inexperienced or untrained personnel to

operate the Tractor or Implement without supervision. Make sure the

operator has fully read and understood the manuals prior to operation.

(SG-4)

The operator and all support personnel should wear hard hats, sa

ety

shoes, safety glasses, and proper hearing protection at all times for

protection from injury including injury from items that may be thrown by

the equipment. (SG-16)

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE

PERMANENT HEARING LOSS! Tractors with or without an Implement

attached can often be noisy enough to cause permanent hearing loss.

We recommend that you always wear hearing protection if the noise in

the Operator’s position exceeds 80db. Noise over 85db over an

extended period of time will cause severe hearing loss. Noise over 90db

adjacent to the Operator over an extended period of time will cause

permanent or total hearing loss. NOTE: Hearing loss from loud noise

[from tractors, chain saws, radios, and other such sources close to the

ear] is cumulative over a lifetime without hope of natural recovery. (SG-I7)

Falling off can result in serious injury or death.

(SG-10)

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)

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. (SG-12)

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

tractor in gear can result in injury or death. Read the Tractor operators

manual for proper starting instructions. (SG-13)

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)

SAFETY

DHM7 05/19 Safety Section 1-7

SAFETY

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

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

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

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

Do Not operate this equipment in areas where insects such as bees, may attack you and/or

cause you to lose control of the equipment. If you must enter in such areas, use a tractor

with an enclosed Cab and close the windows to prevent insects from entering. If a tractor

cab is not available, wear suitable clothing including head, face, and hand protection to

shield you from the insects. Attacking insects can cause you to lose control of the tractor,

which can result in serious injury or death to you or bystanders. Never dismount a moving

tractor. (SG-40)

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

icial

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)

There are obvious and hidden potential hazards in the operation o

this

Mower. REMEMBER! This machine is often operated in heavy brush

and in heavy weeds. The Blades of this Mower can throw objects if

shields are not properly installed and maintained. Serious injury or even

death may occur unless care is taken to insure the safety of the operator,

bystanders, or passersby in the area. Do not operate this machine with

anyone in the immediate area. Stop mowing if anyone is within 300 feet

of mower. (SGM-02)

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)

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)

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

closed. (SGM-11)

mower to cut vegetation above the Mower’s rated capacity or to cut any type of non-

vegetative material. Only operate this Mower on a properly sized and equipped Tractor.

Operating this Mower in an application for which it is not designed and/or operating the

Mower with the wrong size Tractor can cause Mower component damage and equipment

failure resulting in possible serious injury or death. (SGM-14)

Do not operate or pull the mower into standing water. When uplift or fan type mower blades

contact water they can be severely deflected downward causing possible failure of blade

resulting in serious boldly injury to the operator or bystanders. (SGM-15)

Use extreme caution when raising the Mower above ground level. Stop the Blades from

turning when the Mower is raised and passersby are within 100 yards. Raising the

Mower exposes the Cutting Blades which creates a potentially serious hazard and can

cause serious injury by objects thrown from the Blades or by contact with the Blades. (SPU-1)

Disc Mowers are capable under adverse conditions of throwing rocks and other debris for

a considerable distance (50 yards or more) and causing serious bodily injury. Follow safety

messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 50 YARDS UNLESS:

-Front Curtain Shield is installed and in good condition. Replace

when needed with genuine Original Equipment Manufactuers parts.

-Mower cutting head is running close to and parallel to the ground surface.

-Passersby are outside the thrown object zone.

-The area to be cut has been cleared of foreign material such as rocks, cans, glass, and

debris. NOTE: This Disc mower is not to be used for highway maintenance. (SDM-1)

SAFETY

Connecting or Disconnecting Implement Safety Instructions and

Practices

Transporting Safety Instructions and Practices

Disc Mowers rotate at a very high rate of speed (3000 RPM). Vibration due to missing,

broken, or unbalanced components may cause serious imbalance and lead to rapid failure

of components and possible bodily injury from components failure or thrown objects. KEEP

BLADE BOLTS AND DISC ATTACHING BOLTS TIGHTENED TO A SPECIFIED IN

OPERATORS MANUAL TO ASSURE THE INTEGRITY OF THE ASSEMBLIES. (SDM-3)

There are obvious and hidden potential hazards in the operation of the Disc Mower.

REMEMBER! This machine is often operated in hay, grass , and heavy weeds which could

hide foreign objects. Remove all foreign debris before mowing an area. The Blades of this

mower can throw objects if shields are not installed and maintained. Serious injury or even

death may occur unless care is taken to insure the safety of the operator, bystanders, or

passersby in the area. Do not operate this machine with anyone in the immediate area.

Stop mowing if anyone is within 50 yards of mower. (SDM-4)

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)

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)

Be particularly careful when transporting the Implement with the Tractor. Turn curves or go

up hills only at a low speed and using a gradual steering angle. Rear mounted implements

move the center of gravity to the rear and remove weight from the front wheels. Make

certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels

to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough o

uneven surfaces to prevent loss of steering control which could result in property damage

or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched

transport position. Dropping implement in transport can cause serious damage to the

tractor and/or Implement and possibly cause the operator or others to be injured or killed.

(S3PT-02)

SAFETY

DHM7 05/19 Safety Section 1-11

SAFETY

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, serious injury, or even death.

Never allow the Implement to contact obstacles. (S3PT-12)

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in

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)

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)

maintain adequate vision of the public roadway and traffic can result in serious injury or

even death. (STI-10)

When the cutting head is folded for transport, the center of gravity of the Tractor is raised

and the possibility of overturn or tip-over is increased. Serious injury or even death could

result from a tractor turnover. Turn slowly and use extra care on hillsides. Never fold the

cutting head while on a hillside as the tractor might overturn. (SDM-2)

Make sure the PTO shield, integral driveline shields, and input shields

are installed when using PTO-driven equipment. Always replace any

shield if it is damaged or missing. (S3PT-8)

Relieve hydraulic pressure prior to doing any maintenance or repair work

on the Implement. Place the Implement on the ground or securely

blocked up, disengage the PTO, and turn off the tractor engine. Push

and pull the Remote Cylinder lever in and out several times prior to

starting any maintenance or repair work. (S3PT-09)

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)

Always maintain the safety signs in good readable condition. If the safety signs are missing,

damaged, or unreadable, obtain and install replacement safety signs immediately. (SG-5)

Implement, any of its components or any Implement function. (SG-8)

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 serious

injury or even death. (SG-14)

Never attempt to lubricate, adjust, or remove material from the Implement while it is in

motion or while tractor engine is running. (SG-20)

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)

Do Not fill fuel tank while engine is running. Refuel only after engine has cooled down. If

fuel is spilled, move machine away from the area of the spill and avoid creating any source

of ignition until the spill has been cleaned up. (SG-28)

Perform service, repairs and lubrication according to the maintenance section. Ensure the

unit is properly lubricated as specified in the lubrication schedule and all bolts and nuts are

properly torqued. Failure to properly service, repair and maintain this Implement in good

maintenance of equipment. Before you start work at a

new location, check with your supervisor or the safety

coordinator. Ask about the rules you will be expected

to obey.

The Occupational Safety and Health Administration

(OSHA) enforces federal laws within the United

States that apply to safe operation, application and

maintenance of equipment on a worksite. It is the

employer’s responsibility to comply with these laws.

An OSHA representative may periodically inspect a

worksite to see that these laws are being followed.

There may also be local or state/provincial laws or

international regulations that apply to this equipment

and its use, along with speci c worksite or employer

rules. It is important that you know and comply with

all applicable laws and rules, including those requiring

operator training and certi cation.

These are some of the rules you must work by:

— A ROPS and seat belt-equipped tractor is a federal

government (OSHA) requirement for operator

protection during mowing operations. An enclosed

cab provides additional operator protection from

thrown objects. Check your mower operator's manual

to see if a tractor cab is also required.

— Wear and check that others are wearing proper

clothing and personal protective equipment.

— Inspect your machine and attachments before each use

as speci ed by the manufacturer and your employer.

— Know the limitations and operating characteristics of

your mowing equipment. Do not misuse it.

— Have all provided shields and guards properly

installed before operating the machine.

— Never modify or remove any part of the machine

(except for service—then make sure it is replaced).

Mow only in daylight or good arti cial light conditions.

Avoid serious injury or death from mower-thrown

objects or blade contact:

— Keep chain shields,  exible or solid de ector shields

or discharge chutes in place and in good repair.

— Keep bystanders at least 300 ft (92 m) from mowing

operation.

— Never direct mower discharge toward anyone.

— Keep hands, feet and other body parts away from

rotating parts, blades and discharge openings.

— Do not operate mower in transport position.

Do not approach a mower until all motion has stopped.

Mower PTO drive engagement:

— Raise mower to maximum cutting height.

— Engage PTO at low engine rpm.

— Increase engine rpm to mower’s rated rpm PTO speed.

— Lower mower to desired cutting height.

— Stop and shut down immediately if the mower strikes

an obstruction.

— Inspect and repair any mower damage before

resuming mowing.

— Do not operate mower with severe vibrations or with

unusual noise.

Mower-Thrown Objects

Depending on the designed purpose, mowers are

designed to cut grass, weeds, brush and crops. The

mower blades have been designed and tested for

rugged use. The mower blades, however, are not

intended to contact solid objects like rocks, concrete

or metal. Such impact can cause broken objects to be

thrown up to 300 ft (92 m). Bystanders should never

be within 300 ft (92 m) of an operating rotary mower or

within 100 ft (30 M) of a properly equipped disc mower.

Rotating Blades –

Keep Away

Do Not Operate a

Damaged Mower

Operate Safely

Mower shielding is designed to reduce the risk of thrown

objects and must be properly maintained and in place

during mowing operations.

The risk of serious injury or death from thrown objects

can be signi cantly reduced by following three rules.

If all of these safety rules are not followed, the

mowing operation must be stopped if anyone comes

within the safety limit for the mower type.

First — Inspect the area prior to mowing and remove

stones, branches, wire, cable, metal, glass and other

solid objects before operating. Any objects that cannot

be removed must be clearly marked and carefully

avoided by the operator.

In non-crop areas with grass and weeds high enough to

hide objects that could be struck by the blades, inspect

the area and remove or mark large debris or obstacles.

Mow the area at an intermediate height. Inspect the area

closely and remove or mark any remaining debris or

obstacles. Mow again at desired  nal height.

Second — Mower-thrown object shielding must be

used when operating near roads, parks, populated

areas or other areas where thrown objects could

injure bystanders or damage property. Follow the

manufacturer's operator's manual.

Third — Cross diagonally when mowing through

ditches, sharp dips, and drops. Raise the mower to

prevent the mower blades from hitting the ground.

All Mower

Safety Rules

Operate Safely

Mower-Thrown Objects (continued)

Disc Mowers — When using a disc mower it is

important to know the area to be mowed. If the operator

has mowed the  eld before and is familiar with all

obstacles that may be present, it is suf cient to watch

ahead of the mower path for any additional objects that

may have entered the  eld. Be ready to stop or avoid

any objects that could be hazardous if thrown by the

mower. If you plan to mow an unfamiliar  eld and it is

next to a traveled road or people may be within 100

ft (30 m) of the mower you must inspect, and clean or

mark the  eld.

Mowing In Reverse

Do not mow while traveling in reverse. Objects are more

likely to be thrown and can travel further.

Shut off the PTO, wait for the blades to stop turning,

raise the mower, and then back up.

Mow traveling in the forward direction.

Mowing Ground Speed

Proper ground speed depends on terrain conditions and

grass type, density and height to be cut:

— Normal ground speed range is 2 to 5 mph.

— Use slower ground speed for mowing tall, dense grass.

— Use faster ground speed for mowing medium height,

thin grass and under smooth terrain conditions.

— Use slower ground speed for mowing in rough,

sloping or unfamiliar terrain.

Disc mowers are designed to use faster ground speeds

for operating in  elds clear of debris and surface hazards.

Use Proper

Ground Speed

Do Not Mow

in Reverse

Operate Safely

Extremely Tall Grass Mowing

You may need to mow extremely tall, non-crop grass

twice. (See page 13, Mower-Thrown Objects.)

First mowing pass:

— Shut the mower and tractor down using proper

equipment shut down practice before dismounting

tractor. (See page 18, Proper Equipment Shut Down

Practices.)

— Inspect the area and remove or mark debris and

obstacles.

— Cut grass higher (10-15 inches) to avoid hidden objects.

Second mowing pass:

— Shut the mower and tractor down using proper

equipment shut down practice before dismounting

tractor.

— Inspect the area and remove or mark debris and

obstacles.

— Cut grass at desired height and, when possible,

90 degrees to the  rst mowing pass.

Watch Equipment Clearances

Three-point hitch and side-mounted mowers have a

larger turning arc than pull-type mowers. Allow suf cient

clearance for mower swing while turning.

Do not allow bystanders near the tractor and mower

when moving or transporting the tractor and mower.

Wing And Side Mount Mowers Safety Practices

Raised wing positions reduce shielding protection and

increases the thrown object and blade contact hazard

risks.

Avoid possible serious injury or death by thrown

objects or blade contact from raising and lowering

wings during mowing operations:

— Do not mow with bystanders within 300 ft (92 m) of

the mower.

— Be sure no one is near mower while raising or

lowering wings.

— Shut off the PTO and wait for all rotating elements to

stop before raising the mower deck or wing section.

— Only raise wing to clear objects in the mowing path

or to match ground slope.

— Lower raised wing to ground after clearing object or

ground slope conditions.

— Stop mowing if anyone approaches within 300 ft

(92 m) of mowing area.

Ditch Bank Mowing Safety Practices

Use extreme care when mowing ditch banks. Watch for

washouts, eroded areas and mowing obstructions along

the ditch banks. Hitting obstructions with side-mount

or boom mowers may swerve the tractor’s front end

toward the ditch.

Avoid Hitting

Obstructions

Keep Bystanders

— Use enclosed ROPS cabs, special protective

enclosures and other operator shielding available from

the manufacturer when performing these operations.

— Inspect mowing area and remove or mark all foreign

objects and debris to be avoided by mower.

Uneven Terrain Mowing Safety Practices

Tractor and mower stability is reduced on slopes and

uneven terrain.

As in all conditions when mowing, use tractors

equipped with ROPS and seat belt. Make sure the

ROPS are raised and locked in place and always

wear your seat belt.

Prevent tractor and mower overturns and maintain

equipment stability control:

— Review tractor and mower operator’s manuals for

operating safety practices on slopes and uneven

terrain conditions. Explain the practices to those

users and operators who cannot read.

Common Maintenance Safety Practices

Fuel Hazards

WARNING! Always use approved fuel containers

and/or dispensing equipment.

Fuels are  ammable, so observe these practices to

reduce the possibility of a serious accident.

— Shut off engine and ignition during refueling.

— Always ground the fuel nozzle against the  ller neck

to avoid sparks.

— Keep sparks and open  ames away from fuel.

— Do not smoke while refueling or when handling fuel

containers.

— Do not cut or weld on or near fuel lines, tanks or

containers.

— Do not over ll the tank or spill fuel. Clean up spilled

fuel immediately.

Engine Coolant Hazards

Liquid cooling systems build up pressure as the engine

gets hot, so use extreme caution before removing the

radiator cap.

Be sure to:

— Stop the engine and wait for the system to cool.

— Wear protective clothing and safety glasses.

— Turn the radiator cap slowly to the  rst stop to allow

the pressure to escape before removing the cap

completely.

Perform Maintenance Safely

Hydraulic System Hazards

The hydraulic system is under pressure whenever the

engine is operating and may hold pressure even after the

engine is shut off. Cycle all hydraulic controls including

the auxiliary hydraulic control after the engine is shut

down. Relieve trapped pressure in the lines after the

attachments are shut down and resting on the ground.

During inspection of the hydraulic system:

— Wait for  uid to cool before disconnecting the lines.

Hot hydraulic  uid can cause SEVERE BURNS.

— Do not use your hand to check for leaks. Instead,

use a piece of cardboard or paper to search for leaks.

— Wear appropriate eye protection. Hydraulic  uid can

cause permanent eye injury.

WARNING! Hydraulic  uid under pressure can penetrate

the skin or eyes and cause serious injury, blindness or

death. Fluid leaks under pressure may not be visible.

Use a piece of cardboard or wood to ﬁ nd leaks, not

your hand. Wear a face shield or safety goggles for

eye protection. If  uid is injected into the skin, it must

be removed within a few hours by medical personnel

familiar with this type of injury.

When venting or  lling the hydraulic system, loosen the

 ller cap slowly and remove it gradually.

Never reset any relief valve in the hydraulic system to a

pressure higher than recommended by the manufacturer.

Electrical System Hazards

Before working on the electrical system, disconnect the

battery cable(s).

— Remove the battery negative (-) cable(s)  rst.

— When reconnecting the battery, connect the battery

negative (-) cable(s) last.

The liquid in batteries contains acid, which is a POISON

and can cause SEVERE CHEMICAL BURNS.

Avoid Injury

— Wear a face shield to prevent contact with your eyes.

— Wear chemical-resistant gloves and clothing to keep

electrolyte off your skin and regular clothing.

WARNING! Electrolyte will damage eyes or skin

on contact. Always wear a face shield to avoid

electrolyte in eyes. If electrolyte contacts eyes,  ush

immediately with clean water and get medical attention.

Wear chemical-resistant gloves and protective

clothing to keep electrolyte off skin. If electrolyte

contacts exposed skin or clothing, wash off immediately

with clean water. If electrolyte is ingested, seek

medical attention immediately. NEVER give  uids that

would induce vomiting.

Avoid Explosion

WARNING! Avoid possible serious injury from

explosion. Lead-acid batteries produce extremely

explosive gases especially when being charged. Keep

arcs, sparks, ﬂ ames and lighted tobacco away.

— Do not smoke near batteries.

— Keep arcs, sparks and open  ames away from

batteries.

— Provide adequate ventilation.

Never check the battery by placing a metal object

across the battery posts — the resulting spark could

cause an explosion.

WARNING! Avoid possible serious injury from battery

explosion. Do not charge a battery or boost start the

engine if the battery is frozen. Warm to 60°F (15.5°C)

or the battery may explode and could cause serious

injury.

Safety rules during battery boost starting:

— Follow the instructions for proper “battery boost

starting” as speci ed in the manufacturer’s manual.

— Be sure the machines are not touching.

— Observe the polarity of the batteries and connections.

— Make the  nal cable connection to the engine or the

furthest ground point away from the battery. Never

make the  nal connection at the starter or dead

battery—sparks may ignite the explosive gases

present at the battery.

— When disconnecting cables after jump starting,

remove the cables in reverse order of connection

(e.g.,  nal connection  rst).

Tire And Wheel Maintenance

Check your tires and wheels daily because the stability

of the tractor and mower can be dramatically affected

by tire pressure or damage to tires or wheels.

Check tires for:

— Correct pressure.

— Cuts and bulges.

— Nails or other punctures.

— Uneven or excessive wear.

— Condition of valve stems and caps.

Check wheels for:

— Damage to the rims.

— Missing or loose lug nuts or bolts.

— Misalignment.

All tire service should be performed by a quali ed tire

service center or by an authorized service person who

has been properly trained in the procedures and use of

safety equipment designed for tire servicing.

Perform Maintenance Safely

Tire And Wheel Maintenance (continued)

WARNING! The types of wheels and tires usually

found on this equipment require special care when

servicing to prevent death or serious injury.

Do not in ate the tires above the recommended

pressure. Be sure to replace tire ballast if equipped. See

manufacturer’s speci cations for ballast requirements.

Keep wheel lug nuts tightened to manufacturer’s

recommendations.

A rise in tire pressure during operation is normal, and

should NOT be reduced.

Never rein ate a tire that has been run  at or seriously

underin ated without removing the tire from the wheel.

Have the tire and wheel closely inspected for damage

before remounting.

When adding air to a tire, do so from a distance. Use

a long hose with self-attaching chuck. Always stand

behind tread when adjusting tire pressure.

Do not in ate tires with  ammable gases or from

systems using an alcohol injector.

Never cut or weld on a wheel with an in ated

tire mounted on it. This could cause explosive

decompression.

Check that the tire size and wheel are correctly matched.

When replacing the tires, ensure the tires are of the

appropriate rating speci ed by the manufacturer.

Tires should not be operated at speeds higher than their

rated speed. Most agricultural tires are rated for 20mph

maximum speed.

Avoid

Tire Explosion

Perform Maintenance Safely

Complete Service And Repairs Before Machine

Is Released

Tighten all bolts,  ttings, and connections to torques

speci ed by the manufacturer.

Install all guards, covers, and shields after servicing.

Replace or repair any damaged parts. Re ll and

recharge pressure systems only with manufacturer

approved or recommended  uids.

Start the engine and check for leaks. (See page 23,

Hydraulic System Hazards.) Operate all controls

to make sure the tractor and mower are functioning

properly. Test the machine if necessary. After testing,

shut down and check the work you performed. Are

there any missing cotter pins, washers, locknuts, etc.?

Recheck all  uid levels before releasing the equipment

for operation.

All parts should be inspected during repair and replaced

if worn, cracked or damaged. Excessively worn or

damaged parts can fail and cause injury or death.

Replace any damaged or illegible safety signs.

Mower Blade Maintenance

Do not take chances using damaged or bent blades.

The mower manufacturers from the Association

of Equipment Manufacturers (AEM) and the Farm

Equipment Manufacturers Association (FEMA) advocate

that you DO NOT reuse, straighten, hard face or weld

mower blades. Death or serious injury could result if a

broken blade is thrown from a mower.

Verify

Service Work

When

Completed

Perform Maintenance Safely

Mower Blade Maintenance (continued)

— How are mower blades made?

Mower blades are made of high strength alloy spring

steel. They are hot-forged and shaped to meet the

manufacturer’s individual speci cations, then heat

treated and tempered to a high strength, ductile state

to reduce the possibility of breaking while mowing.

Blades are tested to ensure they meet strength,

hardness, and ductility standards. If a blade fails to

meet any of these speci cations, it will not be used

on the mower.

— What happens when a mower blade bends?

It takes a great amount of impact force to bend

the blade. This impact force often results in the

blades being gouged or chipped. After a blade

is damaged by a gouge or chip a blade failure is

much more likely to occur. When a blade is severely

bent, a microscopic crack may be created in the

blade. Straightening the blade does not remove or

repair this crack, but may cause additional cracks.

Additional stresses during mowing operations can

result in an unexpected blade failure.

— Avoid bending blades. Help prevent mower blades

from bending or cracking by avoiding contact with

solid objects. Mower blades are intended to cut

grass, shrubs, woody vegetation, and small trees and

limbs. They are not intended to contact solid objects

such as rocks, concrete, or steel posts. Inspect the

area prior to mowing. Remove or clearly mark any

solid objects and mow around them.

— Replace damaged blades! Inspect the mower blade(s)

daily or after hitting any solid object. If a mower blade

becomes damaged (bent, gouged, cracked) or worn

more than 25 percent of the original size, it should

be removed and replaced with a new blade. Always

use the original manufacturer’s blades. Aftermarket

brand blades may not meet the mower manufacturer’s

strength, hardness and ductility requirements.

— Do not take chances mowing with damaged or

bent blades. Using a damaged or straightened

mower blade can result in the blade breaking and

being thrown into the operator or a bystander causing

death or serious injury. The price of a new blade is

small compared to the potential for the serious injury

that could result from a bent or broken blade being

thrown from the mower.

Objetos arrojados por la cortadora de césped

Dependiendo del propósito previsto, las cortadoras

están diseñadas para cortar hierba, maleza, broza y

cultivos. Las hojas de la cortadora están diseñadas y

probadas para uso intensivo. Las hojas de la cortadora,

sin embargo, no están diseñadas para entrar en contacto

con objetos sólidos como rocas, cemento o metales. Un

impacto de este tipo puede arrojar objetos rotos hasta

300 pies (92 m) de distancia. Nunca debe haber personas

ajenas a menos de 300 pies (92 m) de una cortadora

giratoria en funcionamiento o a menos de 100 pies (30 m)

de una cortadora de disco correctamente equipada.

Hojas giratorias –

Manténgase

No ponga en

funcionamiento una

cortadora de césped

dañada

Operación con seguridad

Los escudos de la cortadora están diseñados para reducir

el riesgo de objetos arrojados y se deben mantener

correctamente y en su lugar durante las operaciones de

corte.

El riesgo de lesiones graves o muerte puede reducirse

signi cativamente si se siguen estas reglas. Si no se

siguen todas estas reglas de seguridad, la operación

de corte debe detenerse en caso de que alguna

persona ingrese dentro del límite de seguridad

correspondiente a cada tipo de cortadora.

Primero — Inspeccione la zona antes de cortar y retire las

piedras, ramas, alambres, cables, metales, vidrios y otros

objetos sólidos antes de hacer funcionar la máquina. Los

objetos que no puedan retirarse deben marcarse con

claridad y ser evitados con cuidado por el operador.

En áreas sin cultivos con hierba y maleza de altura

su ciente como para ocultar objetos que podrían ser

golpeados por las hojas, inspeccione la zona y retire o

marque los residuos u obstáculos grandes.

Realice el corte de la zona a una altura intermedia.

Inspeccione la zona atentamente y retire o marque

cualquier residuo u obstáculo restante. Corte nuevamente

a la altura  nal deseada.

Segundo — Los escudos para objetos arrojados por la

cortadora deben usarse cuando se opera cerca de caminos,

parques, zonas pobladas u otras zonas donde objetos

arrojados podrían lesionar a personas ajenas o dañar la

propiedad. Siga el manual del operador del fabricante.

Tercero — Cruce en sentido diagonal cuando realiza

el corte a través de zanjas, depresiones marcadas y

hundimientos. Eleve la cortadora para evitar que las hojas

de la cortadora golpeen el suelo.

Siga todas

las reglas de

seguridad

Operación con seguridad

Objetos arrojados por la cortadora de césped

(continuación)

Cortadoras de disco — Cuando se usa una cortadora

de disco, es importante conocer la zona donde se va a

cortar. Si el operador ha realizado cortes en el terreno

antes y está familiarizado con todos los obstáculos

que puede haber, es su ciente observar delante de la

trayectoria de la cortadora para detectar cualquier objeto

adicional que pueda haber ingresado en el terreno. Esté

preparado para detenerse o evitar objetos que podrían

ser peligrosos si son arrojados por la cortadora. Si piensa

cortar en un terreno que no conoce bien y se encuentra

junto a un camino transitado o puede haber personas

a menos de 100 pies (30 m) de la cortadora de césped,

debe inspeccionar y limpiar o marcar el terreno.

Cómo cortar en retroceso

No corte mientras se desplaza en retroceso. Es más

probable que se arrojen objetos y que éstos puedan llegar

más lejos.

Apague la TDF, espere que las hojas dejen de girar, eleve

la cortadora y, después, retroceda.

Corte desplazándose en sentido de avance.

Velocidad de desplazamiento durante el corte

La velocidad de desplazamiento correcta depende de las

condiciones del terreno y del tipo de hierba, la densidad y

la altura que debe cortarse:

— El rango normal de velocidad de desplazamiento es de

2 a 5 mph (3.2 a 8 km/h).

— Use una velocidad de desplazamiento menor para

cortar hierbas altas y densas.

— Use una velocidad de desplazamiento mayor para

cortar hierba delgada a altura media y con condiciones

de terreno sin di cultades.

— Use una velocidad de desplazamiento menor par acortar

en terreno irregular, con pendientes o no muy conocido.

Las cortadoras de disco están diseñadas para usar

velocidades de desplazamiento mayores cuando funcionan

en terrenos despejados de residuos y peligros super ciales.

Use la velocidad

de desplazamiento

correcta

Operación con seguridad

Corte de hierba extremadamente alta

Puede ser necesario cortar dos veces la hierba

extremadamente alta que no sea cultivo. (Consulte la página

13, Objetos arrojados por la cortadora de césped.)

Primera pasada de corte:

— Apague la cortadora y el tractor usando la práctica

correcta de apagado de equipos antes de descender del

tractor. (Consulte la página 18, Prácticas correctas de

apagado de los equipos.)

— Inspeccione la zona y retire o marque cualquier residuo u

obstáculo.

— Corte la hierba a mayor altura (10 a 15 pulg. [25 a 38 cm])

para evitar los objetos ocultos.

Segunda pasada de corte:

— Apague la cortadora y el tractor usando la práctica

correcta de apagado de equipos antes de descender

del tractor.

— Inspeccione la zona y retire o marque cualquier residuo

u obstáculo.

— Corte la hierba a la altura deseada y, de ser posible, a

90 grados con respecto a la primera pasada de corte.

Preste atención a los espacios libres de los

equipos

Las cortadoras con enganche de tres puntos y montaje

lateral tienen un arco de giro mayor que las tipo de tiro.

Deje el espacio libre su ciente para la oscilación de la

cortadora cuando gira.

No permita que haya personas ajenas cerca del tractor

y la cortadora de césped cuando mueve o transporta el

tractor y la cortadora.

Operación con seguridad

Prácticas de seguridad para cortadoras de

césped con laterales y montaje lateral

Las posiciones elevadas de los laterales reducen la

protección de los escudos y aumentan los riesgos de

objetos arrojados y contacto con las hojas.

Evite la posibilidad de lesiones graves o muerte por

objetos arrojados o contacto con las hojas causados

por la elevación y el descenso de los laterales durante

las operaciones de corte:

— No realice cortes con personas ajenas presentes a

menos de 300 pies (92 m) de la cortadora de césped.

— Asegúrese de que no haya personas cerca de la

cortadora mientras se elevan o descienden los

laterales.

— Apague la TDF y espere hasta que todos los elementos

giratorios se hayan detenido antes de elevar la

plataforma o la sección lateral de la cortadora.

— Únicamente eleve el lateral para quitar objetos de la

trayectoria de corte o para acompañar una pendiente

del terreno.

— Descienda hasta el suelo el lateral elevado una vez que

se eliminó el objeto o se superó la pendiente.

— Detenga el trabajo de corte si alguna persona se acerca

a menos de 300 pies (92 m) de la zona de corte.

Prácticas de seguridad para trabajos de corte en

orillas de zanjas

Use extremo cuidado al realizar cortes en orillas

de zanjas. Preste atención a escurrimientos, zonas

erosionadas y obstrucciones para el corte a lo largo de

las orillas de zanjas. Si se golpean obstrucciones con

cortadoras de montaje lateral o con aguilón, el extremo

delantero del tractor puede desviarse hacia la zanja.

Operación con seguridad

Los trabajos en orillas de zanjas con aguilón y lateral

elevado pueden reducir la e cacia de la protección del

operador de la cortadora que proporcionan los escudos

para objetos arrojados.

— Cuando realice estas operaciones, use cabinas cerradas

con ROPS, cerramientos protectores especiales y otros

escudos para el operador que ofrece el fabricante.

— Inspeccione la zona de corte y retire o marque todos

los objetos extraños y los residuos que deberá esquivar

la cortadora.

Prácticas de seguridad para trabajos de corte en

terrenos desparejos

Las pendientes y los terrenos desparejos reducen la

estabilidad del tractor y de la cortadora.

Como en todas las condiciones de corte, use tractores

equipados con ROPS y cinturón de seguridad. Asegúrese

de que el ROPS está elevado y trabado en su lugar y

use siempre el cinturón de seguridad.

Prevenga los vuelcos del tractor y de la cortadora de césped

y mantenga controlada la estabilidad de los equipos:

— Repase los manuales del operador del tractor y de la

cortadora para ver las prácticas de seguridad para

operaciones en pendientes y terrenos desparejos.

Explique las prácticas a los operadores que no puedan

leerlas.

— Evite trabajar en pendientes extremadamente

empinadas.

Mantenimiento de neumáticos y ruedas

(continuación)

¡ADVERTENCIA! Los tipos de ruedas y neumáticos

que generalmente se encuentran en estos equipos

requieren cuidados especiales al realizar servicios

para evitar lesiones graves o la muerte.

No in e los neumáticos por encima de la presión

recomendada. Asegúrese de volver a colocar el lastre

de los neumáticos si está instalado. Consulte las

especi caciones del fabricante para ver los requisitos

de lastre.

Mantenga las tuercas de las ruedas apretadas según las

recomendaciones del fabricante.

Es normal que la presión de los neumáticos aumente

durante el funcionamiento; NO se debe reducir.

Nunca vuelva a in ar un neumático que se ha desin ado

mucho o por completo sin retirar el neumático de la

rueda. Haga inspeccionar atentamente el neumático y la

rueda para detectar daños antes de volverlos a armar.

Al agregar aire a un neumático, hágalo desde cierta

distancia. Use una manguera larga con mandril de

auto jación. Siempre párese detrás de la trocha cuando

ajusta la presión de un neumático.

No in e neumáticos con gases in amables o con sistemas

que usan un inyector de alcohol.

Nunca corte o suelde una rueda con un neumático in ado

Realización de mantenimiento con seguridad

Servicio y reparaciones completas antes de

liberar la máquina

Apriete todos los pernos, accesorios y conexiones con las

torsiones especi cadas por el fabricante.

Instale todas las guardas, cubiertas y escudos después

de realizar los servicios. Reemplace o repare los que

estén dañados. Llene y recargue los sistemas a presión

sólo con los  uidos aprobados o recomendados por el

fabricante.

Arranque el motor y revise para detectar fugas. (Consulte

la página 23, Riesgos del sistema hidráulico.) Haga

funcionar todos los controles para asegurarse de que el

tractor y la cortadora de césped funcionan correctamente.

Pruebe la máquina si es necesario. Después de las

pruebas, apague y veri que el trabajo realizado. ¿Falta

algún pasador, arandela, tuerca de seguridad, etc.?

Vuelva a revisar todos los niveles de  uidos antes de

liberar la máquina para el funcionamiento.

Todas las piezas deben ser inspeccionadas durante la

reparación y deben reemplazarse si están gastadas,

rajadas o dañadas. Las piezas excesivamente gastadas o

dañadas pueden fallar y causar lesiones o la muerte.

Reemplace cualquier letrero dañado o ilegible.

Mantenimiento de las hojas de la cortadora

No corra riesgos usando hojas dañadas o dobladas. Los

fabricantes de cortadoras de césped de la Asociación

de Fabricantes de Equipos (Association of Equipment

Manufacturers, AEM) y la Asociación de Fabricantes de

Equipos para Agricultura (Farm Equipment Manufacturers

Association, FEMA) piden que las hojas de cortadoras

NO se reutilicen, enderecen, refuercen en su super cie o

suelden. Si una hoja rota es arrojada por una cortadora,

podrían producirse lesiones graves o la muerte.

Veriﬁ que el trabajo

de servicio cuando

está completo

Realización de mantenimiento con seguridad

Mantenimiento de las hojas de la cortadora

(continuación)

— ¿Cómo están hechas las hojas de la cortadora

de césped? Están hechas acero para resortes de

aleación de alta resistencia. Se forjan en caliente y se

les da forma para cumplir con las especi caciones

individuales del fabricante; luego, se tratan y templan

a un estado dúctil, de alta resistencia para reducir la

posibilidad de rupturas durante el corte. Las hojas se

prueban para garantizar que cumplan con las normas

de resistencia, dureza y ductilidad. Si una hoja no

cumple con alguna de estas especi caciones, no se

utilizará en la cortadora de césped.

— ¿Qué sucede cuando se dobla una hoja de la

cortadora? Se necesita una gran fuerza de impacto

para doblar la hoja. Esta fuerza de impacto a menudo

resulta en que las hojas se agujerean o marcan. Una

vez que una hoja está dañada por un agujero o una

marca, es mucho más probable que ocurra una falla

de la hoja. Cuando una hoja está gravemente doblada,

puede crearse una rajadura microscópica en ella.

Enderezar la hoja no quita o repara esta rajadura, sino

que puede causar rajaduras adicionales.Tensiones

adicionales durante los trabajos de corte pueden

resultar en una falla imprevista de la hoja.

— Evite doblar las hojas. Contribuya a prevenir que las

hojas de la cortadora se doblen o rajen evitando el

contacto con objetos sólidos. Las hojas de la cortadora

de césped están destinadas a cortar hierba, arbustos,

vegetación leñosa y árboles y ramas pequeños. No

están diseñadas para entrar en contacto con objetos

sólidos como roca, cemento o postes de acero.

Inspeccione la zona antes de usar la cortadora. Retire

o marque claramente los objetos sólidos y corte

alrededor de ellos.

— Sustituya las hojas dañadas! Inspeccione las hojas

de la cortadora diariamente o después de golpear

algún objeto sólido. Si una hoja de la cortadora de

césped se daña (está doblada, agujereada, rajada) o

desgasta más del 25 por ciento del tamaño original,

debe retirarse y sustituirse con una nueva. Siempre use

las hojas originales del fabricante. Las hojas de marcas

no originales pueden no cumplir con los requisitos de

resistencia, dureza y ductilidad del fabricante de la

cortadora.

— No corra riesgos usando hojas dañadas o dobladas.

El uso de una hoja de cortadora dañada o enderezada

puede resultar en la ruptura de la hoja y que la hoja

sea arrojada hacia el operador o una persona ajena

causando una lesión grave o la muerte. El precio

de una nueva hoja es bajo en comparación con la

posibilidad de una lesión grave que podría resultar de

una hoja doblada o rota arrojada por la cortadora

DHM7 05/19 Introduction Section 2-3

INTRODUCTION

The DHM mowers have been performance tested and proven to reduce plugging and wrapping in both light

and heavy hay crops. Each cutter bar has been designed with added stiffness to provide exceptional strength

in all working conditions. Oval discs allow for superior flow of material over the cutter bar and a better

distribution of you hay crop. Robust, double-sided steel knives are perfectly timed to overlap at just the right

distance to provide a smooth, clean, clog-free cut.

The gear-driven cutter bar houses oiled and sealed bearings to reduce contamination and provide ease of

maintenance. A hydraulic mower bar cylinder effortlessly lifts the unit for end of field turns and transport.

Ground pressure of the cutter bar can be easily adjusted for a variety of ground conditions. Crop dividers come

standard to provide clear distinction between cut and standing hay.

Mowers feature a mechanical breakaway to protect units from damage when striking an unexpected obstacle.

For Non-Agricultural use, OSHA, ASABE, SAE, and ANSI standards require the use of

Chain Guards, Deflectors, or Solid Skirts at all times. The Mower manufacturer strongly

recommends the use of Chain Guards or Rubber Deflectors for Agricultural purposes as

well, to reduce the risk of property damage, serious bodily injury, or even death from objects

thrown out by or from contact with the Cutting Blades.

At least 20% or the tractor’s weight must be on the front tires with the Mower lifted to

provide adequate traction for safe steering under good conditions. Slow down on hills,

rough terrain, and curves.

The front, rear, left, and right are determined by the normal direction of travel, the same as driving an

automobile.
