Toro Mower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know that is not included in the ANSI standards.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
Use of this product for purposes other than its intended
use could prove dangerous to user and bystanders.
Operation
•Know how to stop the engine quickly.
•Always wear substantial shoes. Do not operate the
machine while wearing sandals, tennis shoes, or
sneakers.
•Wearing safety shoes and long pants is advisable and
required by some local ordinances and insurance
regulations.
•Handle fuel carefully. Wipe up any spills.
•Check the safety interlock switches daily for proper
operation. If a switch should fail, replace the switch
before operating the machine. After every two years,
replace all three interlock switches in the safety
system, regardless if they are working properly or not.
•Using the machine demands attention. To prevent loss
of control:
– Do not drive close to sand traps, ditches, creeks, or
other hazards.
– Reduce speed when making sharp turns. Avoid
sudden stops and starts.
– Watch out for traffic when near or crossing roads.
Always yield the right-of-way.
– Apply the service brakes when going downhill to
keep forward speed slow and to maintain control of
the machine.
•Raise the cutting unit when driving from one work
area to another.
•Do not touch the engine, muffler, or exhaust pipe
while the engine is running or soon after it has stopped
because these areas could be hot enough to cause
burns.
•If a cutting unit strikes a solid object or vibrates
abnormally, stop immediately, turn the engine off, wait
for all motion to stop, and inspect the machine for
damage. A damaged blade must be replaced before
operation is continued.
•Traverse slopes carefully. Do not start or stop suddenly
when traveling uphill or downhill.
•The operator must be skilled and trained in how to
drive on hillsides. Failure to use caution on slopes or
hills may cause loss of control and cause the vehicle to
tip or roll, possibly resulting in personal injury or
death.
•If the engine stalls or loses headway and cannot make
it to the top of a slope, do not turn the machine around.
Always back slowly, straight down the slope.

SAFETY INSTRUCTIONS
•When a person or pet appears unexpectedly in or near
the mowing area, stop mowing. Careless operation,
combined with terrain angles, ricochets, or improperly
positioned guards can lead to thrown object injuries.
Do not resume mowing until the area is cleared.
•Whenever the machine is left unattended, make sure
the cutting unit is disengaged, the key is removed from
the ignition switch, and the parking brake is set.
Maintenance and Storage
•Make sure all hydraulic line connectors are tight and
all hydraulic hoses and lines are in good condition
before applying pressure to the system.
•Keep your body and hands away from pin hole leaks
or nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, not your hands, to
search for leaks. Hydraulic fluid escaping under
pressure can have sufficient force to penetrate the skin
and cause serious injury.
•Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the
cutting units and attachments to the ground.
•Check all fuel lines for tightness and wear on a regular
basis. Tighten or repair them as needed.
•Periodically inspect the roll bar and roll bar mounting.
Repair, as necessary. Do not weld, cut, drill, or modify
roll bar in any manner.
•If the engine must be running to perform a
maintenance adjustment, keep hands, feet, clothing,
and any parts of the body away from the cutting units,
attachments, and any moving parts, especially the
screen at the side of the engine. Keep everyone away.
•Do not overspeed the engine by changing governor
settings. To ensure safety and accuracy, have an
Authorized Toro Distributor check the maximum
engine speed with a tachometer.
•The engine must be shut off before checking the oil or
adding oil to the crankcase.
•If major repairs are ever needed or if assistance is
desired, contact an Authorized Toro Distributor.
•To make sure of optimum performance and continued
safety certification of the machine, use only 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.

OPERATING INSTRUCTIONS
CAUTION
Before servicing or making adjustments to the
machine, stop engine and remove key from
the switch.
STARTING/STOPPING ENGINE
IMPORTANT: The fuel system must be bled if any of
the following situations have occurred:
A. Initial start up of a new machine.
B. Engine has ceased running due to lack of fuel.
C. Maintenance has been performed upon fuel
system components.
D. Refer to Priming Fuel System.
1. Ensure parking brake is set. Remove foot from
traction pedal and insure it is in neutral.
2. Move throttle control to low idle position.
3. Turn ignition key to RUN position, glow indicator
will light.
Note: Do not run starter motor more than 15
seconds at a time or premature starter failure may
result. If engine fails to start after 15 seconds, turn
key to OFF position, recheck controls and
procedures, wait 15 additional seconds and repeat
starter procedure.
4. When glow indicator dims, turn ignition key to
START position. Release key immediately when
engine starts and allow it to return to RUN position.
Move throttle control to desired position.
5. When engine is started for the first time, or after
overhaul of the engine, transmission or axle, operate
the machine in forward and reverse for one or two
minutes. Also operate the lift lever and PTO lever to
assure proper operation of all parts. Turn steering
wheel to the left and right to check steering response.
Then shut engine off and check for oil leaks, loose
parts, and any other noticeable difficulties.
CAUTION
Shut engine off and wait for all moving parts to
stop before checking for oil leaks, loose parts,
or other difficulties.
6. To stop engine, move throttle control backward to
SLOW position, move PTO lever to OFF position, and
rotate ignition key to OFF. Remove key from switch to
prevent accidental starting.
PRIMING FUEL SYSTEM (Fig. 12)
IMPORTANT: The fuel system may need to be
primed when a new engine is started for the first
time, if it runs out of fuel or if maintenance is
performed on the fuel system.
1. Unlatch and raise hood.
2. Insert a 3/16" hose over bleed screw and run other
end into a container to catch fuel.
3. Loosen fuel filter / water separator bleed screw
(Fig. 12) a few turns. Pump priming plunger until a
steady stream of fuel comes out of hole in bleed screw.
When fuel stops foaming, tighten the bleed screw
during the downstroke of the priming plunger. Wipe up
any spilled fuel.

4. Pump priming plunger until resistance is felt. Try to
start engine. If engine does not start repeat step 3.
CHECKING INTERLOCK SWITCHES
The machine has interlock switches in the electrical
system. These switches are designed to stop the
engine when operator gets off the seat when traction
pedal is depressed. However, operator may get off the
seat while engine is running. Although engine will
continue to run if PTO lever is disengaged and traction
pedal is released, it is strongly recommended that the
engine be stopped before dismounting from the seat.
Do not disconnect the interlock switches.
Check operation of switches daily to assure in
terlock system is operating correctly. If a
switch is malfunctioning, replace it before op
erating the machine. To ensure maximum safe
ty, replace all switches after every two years or
1000 hours, whichever comes first.
CAUTION

17
OPERATING INSTRUCTIONS
To check operation of interlock switches:
1. Drive the machine slowly to a large, relatively open
area. Lower cutting unit, stop the engine and apply
parking brake.
2. Sit on seat. Depress the traction pedal. Try to start
the engine. The engine should not crank. If the engine
cranks, there is a malfunction in the interlock system
that should be corrected before beginning operation.
WARNING
Do not operate machine without implement
unless the PTO driveshaft is also removed.
3. Sit on seat and start the engine. Raise off the seat
and move the PTO lever to ON. The PTO should not
engage. If the PTO engages, there is a malfunction in
the interlock system that should be corrected before
beginning operation.
4. With the parking brake engaged, sit on seat and start
the engine. Depress the traction pedal. The engine
should kill when traction pedal is depressed. If the
engine continues to run, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
PUSHING OR TOWING TRACTION UNIT
(Fig. 13)
In an emergency, the traction unit can be pushed or
towed. However, Toro does not recommend this as
standard procedure.
IMPORTANT: Do no push or tow the traction unit
faster than 10 mph. If traction unit must be moved a
considerable distance, transport it on a truck or
trailer.
1. Locate towing lever on right side of axle assembly.
Figure 13

1. Towing Lever
2. Remove cotter pin and clevis pin securing lever to
plate on side of axle.
3. Pivot lever rearward until hole is aligned with rear
hole in plate. Secure lever to rear hole with cotter pin
and clevis pin previously removed.
4. After completion of towing operation, pivot lever
back to original position and re-secure.
OPERATING CHARACTERISTICS
Practice driving the GROUNDSMASTER 3000D
because it has a hydrostatic transmission and its
characteristics are different than many turf
maintenance machines. Some points to consider
when operating the traction unit, cutting unit, or other
implement are the transmission, engine speed, load
on the cutting blades or other implement components,
and the importance of the brakes.
To maintain enough power for the traction unit and
implement while operating, regulate traction pedal to
keep engine rpm high and somewhat constant. A good
rule to follow is: decrease ground speed as the load on
the implement increases, and increase ground speed
as the load decreases.
Therefore, allow traction pedal to move backward as
engine rpm decrease, and depress pedal slowly as
rpm increase. By comparison, when driving from one
work area to anotherwith no load and cutting unit
raisedhave throttle in FAST position and depress
traction pedal slowly but fully to attain maximum
ground speed.
Another characteristic to consider is the operation of
the pedals that are connected to the brakes. The
brakes can be used to assist in turning the machine.
However, use them carefully, especially on soft or wet
grass because the turf may be torn accidentally.
Another benefit of the brakes is to maintain traction. For
example: in some slope conditions, the uphill wheel
slips and loses traction. If this situation occurs, depress
uphill turn pedal gradually and intermittently until the
uphill wheel stops slipping, thus, increasing traction on
the downhill wheel.
Use extra care when operating machine on slopes.
Make sure seat latch is properly secured. Drive slowly
and avoid sharp turns on slopes to prevent roll overs.
The cutting deck must be lowered when going
downhill for steering control.

OPERATING INSTRUCTIONS
WARNING
This product is designed to drive objects into
the ground where they lose energy quickly in
grassy areas. However, when a person or pet
appears suddenly in or near mowing area,
STOP MOWING.
Careless operation, combined with terrain
angle, ricochets, or improperly positioned
safety guards can lead to thrown object inju
ries. Do not resume mowing until area is
cleared.
Before stopping the engine, disengage all controls and
move throttle to SLOW. Moving throttle to SLOW
reduces high engine rpm, noise, and vibration. Turn
key to OFF to stop engine.
Before transporting machine, raise cutting deck and
secure with transport latch.
