Table of Contents

Foreword

The Groundsmaster 3500-D was tested and certified

by TORO for compliance with the B71.4-1999

specifications of the American National Standards

Institute. Although hazard control and accident

prevention partially are dependent upon the design

and configuration of the machine, these factors are

also dependent upon the awareness, concern, and

proper training of the personnel involved in the

operation, transport, maintenance, and storage of

the machine. Improper use or maintenance by the

operator or owner of the machine can result in

injury. To reduce the potential for any injury,

comply with the following safety instructions.

Supervisor’s Responsibilities

1. Make sure operators are thoroughly trained and

familiar with the operator’s manual and all the

labels on the machine.

2. Be sure to establish your own special

procedures and work rules for unusual

operating conditions (e.g., slopes too steep for

machine operation. Survey the complete

mowing site to determine the hills on which the

machine can be safely operated. When

performing this site survey, always use

common sense and take into consideration the

turf condition and the rollover risk.

To determine which hills or slopes on which the

machine may be safely operated, use the

inclinometer provided with each machine. To

perform a site survey, lay a 1.25 meter board on

the slope surface and measure the angle of the

slope. The board will average the slope but will

not take into consideration dips or holes. THE

MAXIMUM SIDE HILL ANGLE SHOULD

NOT BE GREATER THAN 25 DEGREES.

Before Operating

3. Operate the machine only after reading and

understanding the contents of this manual and

viewing the operator’s training video supplied

with the machine. A free replacement manual is

available by sending complete model and serial

number to:

The Toro Company

8111 Lyndale Ave. S.

Bloomington, MN 55420-1196.

4. Only trained operators, skilled in slope

operation and who have read this manual and

viewed the operator’s training video should

operate the machine. Never allow children to

operate the machine or adults to operate it

without proper instructions.

5. Become familiar with the controls and know

how to stop the machine and engine quickly.

6. Do not carry passengers on the machine. Keep

everyone, especially children and pets, away

from the areas of operation.

7. Keep all shields, safety devices and decals in

place. If a shield, safety device or decal is

damaged, malfunctioning or illegible, repair or

replace it before operating the machine.

8. Always wear substantial shoes. Do not operate

machine while wearing sandals, tennis shoes or

sneakers. Do not wear loose fitting clothing

because it could get caught in moving parts and

possibly cause personal injury.

9. Wearing safety glasses, safety shoes, long pants

and a helmet is advisable and required by some

local ordinances and insurance regulations.

10. Make sure the work area is clear of objects

which might be picked up and thrown by the

blades.

11. Fill fuel tank with diesel fuel before starting

engine. Avoid spilling any fuel. Since fuel is

highly flammable, handle it carefully.

A. Use an approved fuel container.

B. Do not remove cap from fuel tank when

engine is hot or running.

C. Do not smoke while handling diesel fuel.

D. Fill fuel tank outdoors and not over one

inch from the top of the tank, (bottom of

the filler neck). Do not overfill.

Safety

While Operating

12. Always wear your seat belt.

13. Do not run the engine in a confined area

without adequate ventilation. Exhaust fumes are

hazardous and could be deadly.

14. Sit on the seat when starting and operating the

machine.

15. Check interlock switches daily for proper

operation (Refer To Checking Interlock

Switches). Do not rely entirely on safety

switches -shut off engine before getting off

seat. If a switch fails, replace it before

operating the machine. The interlock system is

for your protection, so do not bypass it.

Replace all interlock switches every two years.

16. The operator must be skilled and trained in how

to drive on hillsides. Failure to use caution on

slopes or hills may cause vehicle to tip or roll,

possibly resulting in personal injury or death.

17. This triplex mower has a unique drive system

for superior traction on hills. The uphill wheel

will not spin out and limit traction like

conventional triplexes. If operated on a side hill

that is too steep, rollover may occur before

losing traction.

18. Before backing up, look to the rear and assure

no one is behind the machine. Watch out for

traffic when near or crossing roads. Always

yield the right of way.

19. Keep hands, feet and clothing away from

moving parts and the mower discharge area.

20. The slope angle at which the machine will tip is

dependent on many factors. Among these are

mowing conditions such as wet or undulating

turf, speed (especially in turns), position of the

cutting units (with sidewinder), tire pressure

and operator experience. At side hill slope

angles of 20 degrees or less the risk of a

rollover is low. As the slope angle increases to a

Toro recommended maximum limit of 25

degrees the risk of a rollover increases to a

moderate level. DO NOT EXCEED A 25

DEGREE SIDE HILL ANGLE BECAUSE

THE RISK OF A ROLLOVER AND SERIOUS

INJURY OR DEATH IS VERY HIGH. The

Groundsmaster 3500-D is equipped with an

angle indicator, mounted on the steering tube,

which indicates the side hill angle the machine

is operating on and identifies the recommended

maximum limit of 25 degrees.

Stay alert for holes in terrain and other hidden

hazards which can cause a sudden change in

side hill angle. Use extreme caution when

operating close to sand traps, ditches, creeks,

steep hillsides or other hazards. Reduce speed

when making sharp turns. Do not turn on hills.

Avoid sudden stops and starts. Use reverse

pedal for braking. Cutting units must be

lowered when going down slopes for steering

control.

21. When starting the engine:

A. Engage parking brake.

B. Be sure traction pedal is in neutral and

blade drive is in disengage position.

C. After engine starts, release parking brake

and keep foot off traction pedal. Machine

must not move. If movement is evident, the

neutral control linkage is incorrectly

adjusted: therefore, shut engine off and

adjust until machine does not move when

traction pedal is released. Refer to

Adjusting Transmission for Neutral.

22. This product may exceed noise levels of 85

dB(A) at the operator position. Ear protectors

are recommended for prolonged exposure to

reduce the potential of permanent hearing

damage.

23. Raise the cutting units when driving from one

work area to another.

24. Do not touch engine, muffler, exhaust pipe or

hydraulic tank while engine is running or soon

after it has stopped because these areas could

be hot enough to cause burns.

25. If a cutting unit strikes a solid object or vibrates

Safety

abnormally, stop immediately. Turn engine off,

wait for all motion to stop and inspect for

damage.

26. Before getting off the seat:

A. Move traction pedal to neutral.

B. Set the parking brake.

C. Disengage the cutting units and wait for the

blades to stop spinning.

D. Stop the engine and remove key from the

ignition switch.

27. Whenever machine is left unattended, make

sure, key is removed from ignition switch and

parking brake is set.

Maintenance

28. Before servicing or making adjustments to the

machine, stop the engine and remove key from

switch to prevent accidental starting of the

engine.

29. Check performance of all interlock switches

daily. Do not defeat interlock system. It is for

your protection. 30. To ensure entire machine is

in good operating condition, frequently check

and keep all nuts, bolts, screws and hydraulic

fittings tight.

31. Make sure all hydraulic line connectors are

tight, and all hydraulic hoses and lines are in

good condition before applying pressure to the

system.

32. Keep body and hands away from pin hole leaks

or nozzles that eject hydraulic fluid under high

pressure. Use paper or cardboard, not hands, to

search for leaks. Hydraulic fluid escaping under

pressure can have sufficient force to penetrate

skin and do serious damage. If fluid is injected

into the skin it must be surgically removed

within a few hours by a doctor familiar with

this form of injury or gangrene may result. 33.

Before disconnecting or performing any work

on the hydraulic system, all pressure in system

must be relieved by stopping engine and

lowering cutting units to the ground.

34. If major repairs are ever needed or if assistance

is desired, contact an Authorized Toro

Distributor.

35. To reduce potential fire hazard, keep the engine

area free of excessive grease, grass, leaves and

accumulation of dirt.

36. If the engine must be running to perform a

maintenance adjustment, keep hands, feet,

clothing, and any other parts of the body away

from the cutting units and any moving parts.

Keep everyone away.

37. Do not overspeed the engine by changing

governor settings. To assure safety and

accuracy, have an Authorized Toro Distributor

check maximum engine speed with a

tachometer.

38. Engine must be shut off before checking oil or

adding oil to the crankcase.

39. To insure optimum performance and safety, use

genuine TORO replacement parts and

accessories. Replacement parts and accessories

made by other manufacturers could be

dangerous, and such use could void the product

warranty of The Toro Company.
