Safety
This machine meets or exceeds the B71.1-1990
specifications of the American National Standards
Institute, in effect at the time of production.
However, improper use or maintenance by the
operator or owner can result in injury. To reduce
the potential for injury, comply with these safety
instructions and always pay attention to the safety
alert & symbol, which means CAUTION,
WARNING, or DANGER—*personal safety
instruction.” Failure to comply with the
instruction may result in personal injury or death.
Safe Operating Practices
This product is capable of amputating hands and feet
and throwing objects. Always follow all safety
instructions to avoid serious injury or death.
POTENTIAL HAZARD
* Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison.
WHAT CAN HAPPEN
* Carbon monoxide can kill you and is also
known to the State of California to cause
birth defects.
HOW TO AVOID THE HAZARD
* Do not run engine indoors or in an enclosed
area.
General Operation
1. Read, understand, and follow all instructions in
the operator’s manual and on the machine before
starting.
2. Allow only responsible adults who are familiar
with the instructions to operate the machine.
3. Clear the area of objects such as rocks, toys,
wire, etc., which could be picked up and thrown
by the blade.
4. Be sure the area is clear of other people before
mowing. Stop the machine if anyone enters the
area.
5. Never carry passengers.
6. Do not mow in reverse unless absolutely
necessary. Always look down and behind before
and while backing.
7. Be aware of the mower discharge direction and
do not point it at anyone. Do not operate the
mower without either the entire grass catcher or
the guard in place.
8. Slow down before turning. Sharp turns on any
terrain may cause loss of control.
9. Never leave a running machine unattended.
Always turn off blades, set parking brake, stop
engine, and remove key before dismounting.
10. Tum off blades when not mowing.
11. Keep hands, feet, hair and loose clothing away
from attachment discharge area, underside of
mower and any moving parts while engine is
running.
12. Stop the engine before removing the grass
catcher or unclogging the chute.
13.
14.
15.
16.
17.
Mow only in daylight or good artificial light.
Do not operate the machine while under the
influence of alcohol or drugs.
Watch for traffic when operating near or crossing
roadways.
Use extra care when loading or unloading the
machine into a trailer or truck.
Do not touch equipment or attachment parts
which may be hot from operation. Allow to cool
before attempting to maintain, adjust or service.
Slope Operation
Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury or death. All slopes require extra caution. If
you cannot back up the slope or if you feel uneasy on
it, do not mow it.
DO
Mow up and down slopes greater than 5°, not
across.
Mow downhill only on slopes above 10°, never
mow uphill. 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. Choose a low gear so that you
will not have to stop or shift while on the slope.
Follow the manufacturer’s recommendations for
wheel weight or counterweights to improve
stability.
Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.
Safety
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.
DO NOT
Do not operate machine on hillsides or slopes
exceeding 15°.
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.
Do not use a grass catcher on steep slopes.
Heavy grass bags could cause loss of control or
overturn the machine.
Safety
Children
Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the machine and the mowing activity.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for
automotive use (85 pump octane minimum). Leaded
regular gasoline may be used if unleaded regular is
not available.
IMPORTANT: Never use methanol, gasoline
containing methanol, or gasohol containing
more than 10% ethanol because the fuel
system could be damaged. Do not mix oil with
gasoline,
| ÁN DANGER
POTENTIAL HAZARD
* In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
* A fire or explosion from gasoline can burn
you, others, and cause property damage,
HOW TO AVOID THE HAZARD
* Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is cold.
Wipe up any gasoline that spills.
* Do not fill the fuel tank completely full.
Add gasoline to the fuel tank until the level
is 1/4” to 1/2” (6 mm to 13 mm) below the
bottom of the filler neck. This empty space
in the tank allows gasoline to expand.
* Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by a spark.
* Store gasoline in an approved container
and keep it out of the reach of children.
Never buy more than a 30-day supply of
gasoline.
Stabilizer/Conditioner
Toro Stabilizer/Conditioner
Add the correct amount of Toro Gas
Stabilizer/Conditioner to the gas. Using Toro
Stabilizer/Conditioner or an isopropyl-based
conditioner/stabilizer in the machine:
* Keeps gasoline fresh during storage
* Cleans the engine while it runs
* Eliminates gum-like buildup in the fuel system,
which causes hard starting
IMPORTANT: Never use fuel additives
containing methanol or ethanol.
Filling the Fuel Tank
1. Shut the engine off and open the hood.
2. Clean around the fuel tank cap and remove the
cap. Use a funnel and add unleaded regular
gasoline to the fuel tank, until the level is 1/4 to
1/2 inch (6 mm to 13 mm) below the bottom of
the filler neck. This space in the tank allows
gasoline to expand. Do not fill the fuel tank
completely full.
3. Install the fuel tank cap securely. Wipe up any
gasoline that may have spilled.
4, Close the hood.
Check Engine Oil Level
Before you start the engine and use the machine,
check the oil level in the engine crankcase; refer to

The Safety System
Understanding the Safety System
The safety system is designed to prevent the engine
from starting unless:
* You are sitting on the seat
* The clutch/brake pedal is depressed
* The blade control (PTO) is “DISENGAGED”
The safety system is designed to stop the engine if
you rise from the seat when the clutch/brake pedal is
released or the blade is “ENGAGED.”
Testing the Safety System
Test the safety system before you use the machine
each time. If the safety system does not operate as
described below, have an Authorized Service Dealer
repair the safety system immediately.
1. Move the ground speed selector into neutral “N ”
Set the parking brake. Move the blade control
(PTO) to “ENGAGED.” Now turn the ignition
key to “START”; the engine should not crank.
2. With the ground speed selector in neutral “N,”
move the blade control (PTO) to
“DISENGAGED” and release the parking brake.
Now turn the ignition key to “START”; the
engine should not crank.
3. With the ground speed selector in neutral “N,”
set the parking brake and move the blade control
(PTO) to “DISENGAGED.” Now start the
engine. While the engine is running, release the
parking brake and rise slightly from the seat; the
engine should stop.
Operation
13
Operation
Driving Forward or Backward
The throttle control regulates the engine speed as
measured in rpm (revolutions per minute).
To go forward or backward, depress the clutch/brake
pedal. Move the ground speed selector to the desired
forward speed or reverse. As you slowly release the
pedal, the machine will begin to move. Steer the
machine with the steering wheel.
POTENTIAL HAZARD
* If you release the clutch/brake pedal too
quickly when the ground speed selector is
in gear, you could suddenly put the
machine in motion.
WHAT CAN HAPPEN
* Sudden engagement of the machine's drive
system could cause you to lose control.
HOW TO AVOID THE HAZARD
* Always release the clutch/brake pedal
slowly when starting the machine in motion
(forward or reverse).
Selecting Ground Speeds
IMPORTANT: To avoid transmission
damage, always depress the clutch/brake
pedal before shifting into or out of reverse.
Always start the machine in motion by depressing the
clutch/brake pedal and shifting into the desired speed.
Once the machine is in motion, you can shift into any
forward speed without depressing the clutch/brake
pedal. In most conditions, the machine is powerful
enough to move out in any speed. If it will not move
out in a selected speed (i.e., 45) due to a heavy load,
use a lower speed (i.e., 42).
14
Stopping the Machine
To stop the machine, depress the clutch/brake pedal,
shift into neutral, disengage the blade control (PTO),
and tum the ignition key to “OFF” to stop the engine.
Also set the parking brake if you leave the machine
unattended; refer to Setting the Parking Brake,
page 9. Remember to remove the key from the
ignition switch.
ÁN CAUTION
POTENTIAL HAZARD
* Someone could move or attempt to operate
the tractor while it is unattended.
WHAT CAN HAPPEN
* Children or bystanders may be injured if
they use the tractor.
HOW TO AVOID THE HAZARD
* Always remove the ignition key and set the
parking brake when leaving the machine
unattended, even if just for a few minutes.
Side Discharge
or Mulch Grass
ÁN DANGER
POTENTIAL HAZARD
* Without the grass deflector, discharge
cover, or complete grass catcher assembly
mounted in place, you and others are
exposed to blade contact and thrown
debris.
WHAT CAN HAPPEN
* Contact with rotating mower blade(s) and
thrown debris will cause injury or death.
HOW TO AVOID THE HAZARD
* NEVER remove the grass deflector from
the mower because the grass deflector |
routes material down toward the turf, If the
grass deflector is ever damaged, replace it
immediately.
* Never put your hands or feet under the
mower.
* Never try to clear discharge area or mower
blades unless you move the blade control
(PTO) to “DISENGAGED” and rotate the
ignition key to “OFF.” Also remove the key
and pull the wire off the spark plug.
Operation
1. The mower has a hinged grass deflector that
disperses clippings to the side and down toward
the turf.
2. To mulch grass clippings you must install the
discharge cover (optional on some models) into
the opening in the side of the mower; refer to
Installing the Discharge Cover, page 15.
Installing the
Discharge Cover
To convert from side discharge to a mulching mower,
install the discharge cover into the opening at the side
of the mower.
1. Lift the grass deflector and place the discharge
cover over the opening onto the lower lip of the
mower and slide into the front hinge (Fig. 11).
N
Slide the hinge pin through the hinge (Fig. 11).
3. Secure the discharge cover to the mower with the
wing nut (Fig. 11).

Operation
Tips for Mowing Grass
Fast Throttle Setting
For best mowing and maximum air circulation,
operate the engine at “FAST.” Air is required to
thoroughly cut grass clippings, so do not set the
height-of-cut too low or totally surround the mower
by uncut grass. Always try to have one side of the
mower free from uncut grass, which allows air to be
drawn into the mower.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure the
cutting height of the mower does not scalp any
uneven ground. However, the cutting height used in
the past is generally the best one to use. When cutting
grass longer than six inches tall, you may want to cut
the lawn twice to assure an acceptable quality-of-cut.
Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade.
Cutting more than that is not recommended, unless
grass is sparse or it is late fall when grass grows more
slowly.
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which
enhances decomposition and fertilization.
Mow at Correct intervals
Normally, mow every 4 days. But remember, grass
grows at different rates at different times. So to
maintain the same cutting height, which is a good
practice, mow more often in early spring. As the
grass growth rate slows in mid summer, mow less
frequently. If you cannot mow for an extended period,
first mow at a high cutting height; then mow again 2
days later at a lower height setting.
16
Avoid Cutting Too Low
If the cutting width of the mower is wider than the
mower you previously used, raise the cutting height
one notch to ensure uneven turf is not cut too short.
Long Grass
If the grass is ever allowed to grow slightly longer
than normal, or if it contains a high degree of
moisture, raise the cutting height higher than usual
and cut the grass at this setting. Then cut the grass
again using the lower, normal setting.
When Stopping
If the machine’s forward motion must be stopped
while mowing, a clump of grass clippings may drop
onto your lawn. To avoid this:
1. With the blade(s) “ENGAGED,” move onto a
previously cut area.
2. To disperse the clippings evenly, raise the mower
one or two height-of-cut settings while driving
forward with the blade(s) “ENGAGED.”
Keep the Underside of the Mower Clean
Clean clippings and dirt from the underside of the
mower after each use. If grass and dirt build up inside
the mower, cutting quality will eventually become
unsatisfactory.
Blade Maintenance
Maintain a sharp blade throughout the cutting season
because a sharp blade cuts cleanly without tearing or
shredding the grass blades. Tearing and shredding
turns grass brown at the edges, which slows growth
and increases the chance of disease. Every 30 days,
check the cutter blade(s) for sharpness and file down
any nicks.

WHAT CAN HAPPEN
* Accidental starting of the engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
* Remove the key from the ignition switch and pull the wire off the spark plug before
you do any maintenance. Also push the wire aside so it does not accidentally contact
the spark plug.
Maintenance

Side-to-Side Mower Leveling
The mower blades must be level from side to side.
Check the side-to-side level any time you install the
mower or when you see an uneven cut on your lawn.
Before you level the mower, set the air pressure in the
front and rear tires to 12 psi (.85 kPa).
1. Park the machine on a level surface, disengage
the blade control (PTO), shift into neutral, set
the parking brake, and turn the ignition key to
“OFF” to stop the engine.
2. Remove the key from the ignition switch and

7. Check the front-to-rear slope again. If the front
of the mower is more than 5/8” (15.875 mm)
lower than the rear of the mower, proceed to
step 8 for adjusting instructions. Otherwise,
recheck the side-to-side level to assure it did not
change.
8. Adjust the front-to-rear slope by rotating the
special slope adjusting nuts on both sides of the
mower pivot mount (Fig. 50).
9. Using a 1” wrench or socket slowly rotate the
left side slope adjusting nut down to raise the
front of the mower and up to lower it (Fig. 50).
Rotate the slope adjusting nut until the front of
the mower is 1/4” to 5/8” (6.350 mm to
15.875 mm) lower than the rear of the mower.
10. Now slowly rotate the right side slope adjusting
nut until both adjusting nuts are in the same
position.
IMPORTANT: If the slope adjustment does
not stay in position after you adjust it,
tighten the center bolt and lock nut and
repeat step 9.

Clean dirt and chaff from the outside of the
engine’s cylinder head fins and blower housing.
Also remove grass clippings, dirt, and grime
from the external parts of the entire machine,
especially the engine, shrouding, and the top of
the mower.
IMPORTANT: You can wash the machine
with mild detergent and water. Do not
pressure wash the machine. Avoid excessive
use of water, especially near the control panel,
lights, engine, and the battery.
Scrape heavy buildup of grass and dirt from the
underside of the mower. Then wash the mower
with a garden hose.
Check the condition of the blade(s); refer to
Cutting Blade, page 32.
Check the condition of the blade drive belt.
Check the brake; refer to Brake, page 19.
Service the air cleaner; refer to Air Cleaner,
page 28.
Grease the chassis; refer to Greasing and
Lubrication, page 18.
Change the crankcase oil; refer to Engine Oil,
page 30.
Remove the spark plug and check its condition,
refer to Spark Plug, page 24. With the spark plug
removed from the engine, pour two tablespoons
of engine oil into the spark plug hole. Now use
the electric starter to crank the engine and
distribute the oil inside the cylinder. Install the
spark plug and tighten it to 15 ft-1b (20.4 Nm).
Do not install the wire on the spark plug.
Remove the battery from the chassis, check the
electrolyte level, and charge it fully; refer to
Battery, page 22. Do not connect the battery
cables to the battery posts during storage.

IMPORTANT: The battery must be fully
charged to prevent it from freezing and being
damaged at temperatures below 32°F (0°C). À
fully charged battery maintains its charge for
about 50 days at temperatures lower than
40°F (4°C). If the temperatures will be above
40°F (4°C), check the water level in the
battery and charge it every 30 days.
Check the tire pressure; refer to Tire Pressure,
page 19.
During long-term storage, either drain gasoline
from the fuel tank (step A) or add a fuel additive
to a full tank of gasoline (step B).
A. Drain gasoline from the fuel tank; refer to
Fuel Tank, page 25. After fuel is drained,
start the engine and let it idle until all
gasoline is consumed and the engine stops.
This eliminates gum-like buildup in the fuel
system, which causes hard starting. Try to
start the engine two more times to assure
that no gasoline is in the fuel system.
B. Add the correct amount of Toro
Stabilizer/Conditioner or an
isopropyl-based stabilizer/conditioner to a
full tank of gasoline.
Note: Stabilizer/conditioners normally
preserve gasoline for six to eight
months.
Check and tighten all bolts, nuts, and screws.
Repair or replace any part that is damaged or
defective.
Paint all scratched or bare metal surfaces. Paint
is available from you Authorized Service Dealer.
Store the machine in a clean, dry garage or
