trailer or truck
•Use care when approaching blind corners, shrubs, trees,
or other objects that may obscure vision.
Maintenance and storage
•Disengage drives, lower implement, set parking brake,
stop engine and remove key. Wait for all movement to
stop before adjusting, cleaning or repairing.
•Clean grass and debris from cutting units, drives,
mufflers, and engine to help prevent fires. Clean up oil
or fuel spillage.
•Let engine cool before storing and do not store near
flame.
•Do not store fuel near flames or drain indoors.
•Park machine on level ground. Never allow untrained
personnel to service machine.
•Use jack stands to support components when required.
•Carefully release pressure from components with stored
energy.
•Disconnect battery before making any repairs.

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.

5
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
This product is designed for cutting and recycling grass.
Any use for purposes other than these could prove
dangerous to user and bystanders.
General Operation
•Allow only responsible adults who are familiar with the
instructions to operate the machine.
•Be sure the area is clear of other people before mowing.
Stop the machine if anyone enters the area.
•Do not mow in reverse unless absolutely necessary.
Always look down and behind before and while
backing.
•Slow down before turning. Sharp turns on any terrain
may cause loss of control.
•Turn off blades when not mowing.
•Keep hands, feet, hair and loose clothing away from
attachment discharge area, underside of mower and any
moving parts while engine is running.
•Mow only in daylight or good artificial light.
•Watch for traffic when operating near or crossing
roadways.
•Do not touch equipment or attachment parts which may
be hot from operation. Allow to cool before attempting
to maintain, adjust or service.
•Before operating a machine with ROPS (roll over
protection) be certain the seat belts are attached and seat
is latched to prevent the seat from pivoting forward.
•Use only Toro-approved attachments. Warranty may be
voided if used with unapproved attachments.
Slope Operation
Slopes and ramps are a major factor related to
loss-of-control and tip-over accidents, which can result in
severe injury or death. All slopes and ramps require extra
caution. If you cannot back up the slope or if you feel
uneasy on it, do not mow it.
DO
•If a steep slope must be ascended, back up the hill, and
drive forward down the hill, keeping the machine in
gear.
•Remove obstacles such as rocks, tree limbs, etc. from
the mowing area. Watch for holes, ruts or bumps, as
uneven terrain could overturn the machine. Tall grass
can hide obstacles.
•Use slow speed so that you will not have to stop while
on the slope.
•Follow the manufacturer’s recommendations for wheel
weights or counterweights to improve stability.
•Use extra care with other attachments. These can
change the stability of the machine.
•Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction.
•Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope. Avoid raising side decks on a
slope.
•When operating machine on slopes, banks or near drop
offs, always have ROPS (roll over protection) installed.
•When operating a machine with ROPS (roll over
protection) always use seat belt.
•Be certain that the seat belt can be released quickly if
the machine is driven or rolls into ponds or water.
•Check carefully for overhead clearances (i.e. branches,
doorways, electrical wires) before driving under any
objects and do not contact them.
DO NOT
•Do not mow slopes exceeding 15 degrees.
•Avoid turning on slopes. If you must turn, turn slowly
and gradually downhill, if possible.
•Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel goes
over the edge of a cliff or ditch, or if an edge caves in.
•Do not mow on wet grass. Reduced traction could cause
sliding.
•Do not try to stabilize the machine by putting your
foot on the ground.
Service
•Never store the machine or fuel container inside where
there is an open flame, such as near a water heater or
furnace.
•Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good condition.
•Never tamper with safety devices. Check safety systems
for proper operation before each use.
•Use only genuine replacement parts to ensure that
original standards are maintained.
•Check brake operation frequently. Adjust and service as
required.

6
•Battery acid is poisonous and can cause burns. Avoid
contact with skin, eyes and clothing. Protect your face,
eyes and clothing when working with a battery.
•Battery gases can explode. Keep cigarettes, sparks and
flames away from battery.
•Hydraulic fluid escaping under pressure can penetrate
the skin and cause injury. Use cardboard or paper to
find hydraulic leaks. Never use your hands.

Before Operating
Check Engine Oil
The engine is shipped with 4 qt (3.8 l) of oil in the
crankcase; however, level of oil must be checked before
and after the engine is first started.
1. Park machine on a level surface, stop engine and
remove key from ignition switch. Open hood.
2. Remove dipstick (Fig. 13), wipe clean and reinstall
dipstick. Remove dipstick and check oil level. Oil level
should be up to FULL mark on dipstick

Figure 13
1. Dipstick 2. Oil fill
3. If oil is below FULL mark, remove fill cap and add
SAE 10W–30 CD, CE, CF, CF–4 or CG–4
classification oil until level reaches FULL mark on
dipstick. DO NOT OVERFILL.
4. Install oil fill cap and close hood.
Check Cooling System
Clean debris off screen and radiator/oil cooler daily, more
often if conditions are extremely dusty and dirty; refer to
section on Engine Cooling System.
The cooling system is filled with a 50 / 50 solution of water
and permanent ethylene glycol anti–freeze. Check level of
coolant in expansion tank at beginning of each day before
starting the engine. Capacity of cooling system is 7quarts
(6.6 l).
•If engine has been running, pressurized hot
coolant can escape when radiator cap is
removed and cause burns.
Caution
1. Check level of coolant in expansion tank. Coolant level
should be between the marks on side of tank.

Figure 14
1. Expansion tank
Figure 15
1. Expansion Tank
2. If coolant level is low, remove expansion tank cap and
replenish the system. DO NOT OVERFILL.
3. Install expansion tank cap.
Check Hydraulic System Fluid
The hydraulic system was designed to operate on any high
quality detergent oil having the American Petroleum
Institute—API—“service classification” SF, CC or CD. Oil
viscosity — weight — must be selected according to
anticipated ambient temperature. Temperature/viscosity
recommendations are:
Expected Ambient
Temperature Recommended Viscosity
and Type
(Extreme) over 90F SAE 30, Type SF, CC or
CD engine oil.
(Normal) 40–100F SAE 10W-30 or 10W-40.
Type SF, CC or CD engine
oil.
(Cool–Spring/Fall)
30–50F SAE 5W-30, Type SF, CC or 30–50F CD engine oil.
(Winter) Below 30F Type “F” or “FA” ATF
Automatic Transmission
Fluid.
Note: Do not mix engine oil and automatic transmission
fluid or hydraulic component damage may result. When
changing fluids, also change transmission filter. DO NOT
USE DEXRON II ATF.

20
The axle housing acts as the reservoir for the system. The
transmission and axle housing are shipped from the factory
with approximately 5 quarts (4.7 l) of SAE 10W-30 engine
oil. However, check level of transmission oil before engine
is first started and daily thereafter.
1. Position machine on a level surface. Place all control in
neutral position and start the engine. Run engine at
lowest possible RPM to purge the system of air. DO
NOT ENGAGE PTO. Cycle steering wheel several
times fully to the left and right. Raise the cutting unit to
extend lift cylinders, aiming steering wheels straight
forward and stop the engine.
2. Remove dipstick cap (Fig. 16) from filler neck and wipe
it with a clean rag. Screw dipstick cap finger-tight onto
filler neck; then remove it and check level of fluid. If
level is not within 1/2 inch (13 mm) from the groove in
the dipstick (Fig. 16), add SAE 10W-30 engine oil, or,
if used, automatic transmission fluid to raise level to
groove mark. Do not overfill.

Figure 16
1. Hydraulic system reservoir fluid/add dipstick cap
Important When adding transmission fluid to the
hydraulic system, use a funnel with a fine wire screen —
200 mesh or finer — and make sure funnel and
transmission fluid are immaculately clean. This procedure
prevents accidental contamination of the hydraulic system.
3. Thread dipstick fill cap finger-tight onto filler neck. It is
not necessary to tighten cap with a wrench.
4. Check all hoses and fittings for leaks.
Fill Fuel Tank
Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
•Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
•Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
•Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
•Store fuel in a clean, safety-approved container
and keep the cap in place.
1. Using a clean rag, clean area around fuel tank cap.
2. Remove cap from the fuel tank (Fig. 17).
3. Fill the 8.5 gallon (32 l) tank to within 1 inch (25 mm)
from the bottom of the filler neck with diesel fuel.
4. Install fuel tank cap tightly after filling tank.
