5. Rev. GGreensmaster 3250−D Page 1 − 3 Safety
While Operating
10. Do not run the engine in a confined area without ad-
equate ventilation. Exhaust fumes are hazardous and
could be deadly.
11. Sit on the seat when starting and operating the ma-
chine.
12. Check the operation of the interlock switches daily
for proper operation (see Verify Interlock System Opera-
tion in Chapter 5 − Electrical System). Replace any mal-
functioning switches before operating the machine.
13. To start the engine:
A. Sit on the seat, make sure cutting units are dis-
engaged.
B. Verify that functional control lever is in neutral.
C. Verify that parking brake is set.
D. Proceed to start engine.
14. Using the machine demands attention, and to pre-
vent loss of control:
A. Mow only in daylight or when there is good artifi-
cial light.
B. Watch for holes or other hidden hazards.
C. Do not drive close to sand traps, ditches, creeks
or other hazards.
D. Reduce speed when making sharp turns. Avoid
sudden stops and starts.
E. Before backing up, look to the rear to be sure no
one is behind the machine.
F. Watch out for traffic when near or crossing
roads. Always yield the right−of−way.
G. Apply the service brakes when going downhill to
keep forward speed slow and to maintain control of
the machine.
15. Keep hands, feet and clothing away from moving
parts and the reel discharge area. The grass baskets
must be in place during operation of the reels or thatch-
ers for maximum safety. Shut the engine off before emp-
tying the baskets.
16. The GREENSMASTER 3250−D may exceed noise
levels of 85 dB(A) at the operator position. Ear protec-
tors are recommended, for prolonged exposure, to re-
duce the potential of permanent hearing damage.
17. Raise the cutting units when driving from one work
area to another.
18. Do not touch engine, muffler or exhaust pipe while
engine is running or soon after it is stopped because
these areas could be hot enough to cause burns.
19. If a cutting unit strikes a solid object or vibrates ab-
normally, stop immediately, turn engine off, wait for all
motion to stop and inspect for damage. A damaged reel
or bedknife must be repaired or replaced before opera-
tion is continued.
20. Before getting off the seat:
A. Make sure cutting units are disengaged.
B. Verify that functional control system is in neutral.
C. Set the parking brake.
D. Stop the engine and remove key from ignition
switch.
21. Traverse slopes carefully. Do not start or stop sud-
denly when traveling uphill or downhill.
22. Operator must be skilled and trained in how to drive
on hillsides. Avoid wet slopes. Failure to use caution on
slopes or hills may cause loss of control and vehicle to
tip or roll possibly resulting in personal injury or death.
23. If engine stalls or loses headway and cannot make
it to the top of a slope, do not turn machine around. Al-
ways back slowly straight down the slope.
24. DON’T TAKE AN INJURY RISK! 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 area is cleared.
25. Whenever machine is left unattended, make sure
cutting units are fully raised and reels are not spinning,
key is removed from ignition switch and parking brake
is set.

Maintenance and Service
26. Before servicing or making adjustments to the ma-
chine, stop the engine, remove key from switch to pre-
vent accidental starting of the engine.
27. Be sure entire machine is in good operating condi-
tion. Keep all nuts, bolts, screws and hydraulic fittings
tight.
28. Make sure all hydraulic line connectors are tight,and
all hydraulic hoses and lines are in good condition be-
fore applying pressure to the system.
29. 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 suffi-
cient force to penetrate skin and do serious damage. If
fluid is ejected 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.
30. Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be re-
lieved by stopping engine and lowering cutting units and
attachments to the ground.
31. To reduce potential fire hazard, keep the engine
area free of excessive grease, grass, leaves and accu-
mulation of dirt. Never wash a warm engine or electrical
connections with water.
32. Check all fuel lines for tightness and wear on a regu-
lar basis, and tighten or repair as needed.
33. If the engine must be running to perform a mainte-
nance adjustment, keep hands, feet, clothing and any
other parts of the body away from the cutting units, at-
tachments and any moving parts. Keep everyone away.
34. Do not overspeed the engine by changing governor
settings. To assure safety and accuracy, have an Autho-
rized Toro Distributor check maximum engine speed
with a tachometer. Maximum governed engine speed
should be 2750 + 50 RPM.
35. Engine must be shut off before checking oil or ad-
ding oil to the crankcase.
36. If major repairs are ever needed or if assistance is
desired, contact an Authorized Toro Distributor.
37. At the time of manufacture, the GREENSMASTER
3250−D conformed to safety standards in effect for rid-
ing mowers. To make sure of optimum performance and
continued safety certification of the machine, use genu-
ine TORO replacement parts and accessories. Re-
placement parts and accessories made by other
manufacturers could be dangerous, and such use could
void the product warranty of The Toro Company.
38. When changing attachments, tires, or performing
other service, use correct blocks, hoists, and jacks.
Make sure machine is parked on a solid level floor such
as a concrete floor. Prior to raising the machine, remove
any attachments that may interfere with the safe and
proper raising of the machine. Always chock or block
wheels. Used jack stands or solid wood blocks to sup-
port the raised machine. If the machine is not properly
supported by blocks or jack stands, the machine may
move or fall, which may result in personal injury.
Safety and Instruction Decals
Numerous safety and instruction decals are affixed to
the traction unit. If any decal becomes illegible or dam-
aged, install a new decal. Part numbers are listed in your
Parts Catalog. Order replacement decals from your Au-
thorized Toro Distributor.

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as determined
by Toro, either the recommended torque or a torque that
is unique to the application is clearly identified and spe-
cified in this Service Manual.
These Torque Specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in this Ser-
vice Manual. The following factors shall be considered
when applying torque: cleanliness of the fastener, use
of a thread sealant (Loctite), degree of lubrication on the
fastener, presence of a prevailing torque feature, hard-
ness of the surface underneath the fastener’s head, or
similar condition which affects the installation.
As noted in the following tables, torque values should be
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread en-
gagement, etc.
The standard method of verifying torque shall be per-
formed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.

Note: Reduce torque values listed in the table above
by 25% for lubricated fasteners. Lubricated fasteners
are defined as threads coated with a lubricant such as
oil, graphite, or thread sealant such as Loctite.
Note: Torque values may have to be reduced when
installing fasteners into threaded aluminum or brass.
The specific torque value should be determined based
on the fastener size, the aluminum or base material
strength, length of thread engagement, etc.
Note: The nominal torque values listed above are
based on 75% of the minimum proof load specified in
SAE J1199. The tolerance is approximately + 10% of the
nominal torque value.

General Information
DANGER
Because diesel fuel is flammable, use caution
when storing or handling it. Do not smoke while
filling the fuel tank. Do not fill fuel tank while en-
gine is running, hot, or when machine is in an en-
closed area. Always fill fuel tank outside and
wipe up any spilled diesel fuel before starting the
engine. Store fuel in a clean, safety−approved
container and keep cap in place. Use diesel fuel
for the engine only; not for any other purpose.
Fuel Shutoff Valve
This valve should be shut when removing the engine or
placing the unit in long term storage.

Checking Engine Oil
IMPORTANT: Check level of oil every 8 operating
hours or daily.
Crankcase capacity is approximately 3.5 qts. (3.3 L)
with filter.
1. Position machine on a level surface.
2. Remove dipstick and wipe it with a clean rag. Push
dipstick into the tube and make sure it is seated fully. Re-
move dipstick from tube and check level of oil. If oil level
is low, remove filler cap from valve cover and add
enough oil to raise level to FULL mark on dipstick. Add
the oil slowly and check the level often during this pro-
cess. DO NOT OVERFILL.
3. The engine uses any high-quality detergent oil hav-
ing the American Petroleum Institute -API- “service clas-
sification” CD, CE, CF or CF−4 or CG−4 or higher.
Recommended viscosity (weight) is SAE 10W30.

Drain Water from Fuel Filter/Water Separator
Any water accumulation should be drained from the fuel
filter/water separator before each use or when warning
light glows.
1. Position machine on a level surface and stop the en-
gine.
Note: Because the accumulated water will be mixed
with diesel fuel, drain the fuel filter into a suitable con-
tainer and dispose of properly.
2. Place a drain pan under the fuel filter.
3. Open the drain plug on the fuel filter/water separator
approximately one turn and drain any accumulated wa-
ter. If necessary, operate the priming pump to drain wa-
ter. Tighten the plug after draining.
