Ignition Switch
Motion-Control Levers
The ignition switch has 3 positions: START, RUN, and OFF..
The key will turn to the START position and move back to
the RUN position upon release. Turning the key to the OFF
position shuts off the engine; however, always remove the
key when leaving the machine to prevent the engine from
accidentally starting (Figure 5).
The motion-control levers are speed-sensitive controls of
independent-wheel motors. Moving a lever forward or
backward turns the wheel on the same side forward or
in reverse; wheel speed is proportional to the amount the
lever is moved. Move the control levers outward from the
center to the NEUTRAL-LOCK position and exit the machine
(Figure 4). Always position the motion-control levers into
the NEUTRAL-LOCK position when you stop the machine
or leave it unattended.
Throttle Control
The throttle control is variable between the FAST and SLOW
position. Moving throttle lever forward increases engine
speed and moving throttle lever to the rear decreases engine
speed. Moving the throttle forward into the detent is full
throttle (Figure 5).
Parking-Brake Lever
Choke
The parking-brake lever is located on left side of the console
(Figure 4). The brake lever engages a parking brake on the
drive wheels. Pull the lever up and rearward to engage the
brake. Push the lever forward and down to disengage the
brake.
Use the choke to start a cold engine. Pull the choke knob up
to engage it. Push down on the choke knob to disengage it.
Foot Pedal Deck-Lift System
The foot pedal deck-lift system allows the operator to lower
and raise the deck from the seated position. You can use the
foot pedal to lift the deck briefly to avoid obstacles or lock
the deck in the highest height of cut or transport position
(Figure 4).
Blade-Control Switch (Power Takeoff)
The blade-control switch engages and disengages power to
the mower blades (Figure 5).
Hour Meter
Height-of-Cut Lever
The hour meter records the number of hours the blades
operate. It operates when the blade-control switch (PTO) is
engaged. Use these times for scheduling regular maintenance
(Figure 5).
The height-of-cut lever works with the foot pedal to lock the
deck in a specific cutting height. Only adjust the height of cut
while machine is not moving (Figure 4).
Fuel Gauge
Attachments/Accessories
The fuel window located below the operator position can be
used to verify the level of gasoline in the tank (Figure 6).
A selection of Toro approved attachments and accessories is
available for use with the machine to enhance and expand
its capabilities. Contact your Authorized Service Dealer or
Distributor or go to www.Toro.com for a list of all approved
attachments and accessories.

Operation
WARNING
Gasoline is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.
Note: Determine the left and right sides of the machine
from the normal operating position.
Adding Fuel
• For best results, use only clean, fresh, unleaded gasoline
with an octane rating of 87 or higher ((R+M)/2 rating
method).
• Oxygenated fuel with up to 10% ethanol or 15% MTBE
DANGER
by volume is acceptable.
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or explosion
from gasoline can burn you and others and can
damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Never fill the fuel tank inside an enclosed trailer.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 6 to 13
mm (1/4 to 1/2 inch) 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.
• Do not operate without entire exhaust system in
place and in proper working condition.
• Do not use ethanol blends of gasoline (such as E15
or E85) with more than 10% ethanol by volume.
Performance problems and/or engine damage may result
which may not be covered under warranty.
• Do not use gasoline containing methanol.
• Do not store fuel either in the fuel tank or fuel containers
over the winter unless a fuel stabilizer is used.
• Do not add oil to gasoline.
DANGER
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the gasoline vapors. A fire or explosion
from gasoline can burn you and others and can
damage property.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior carpets
or plastic truck bed liners may insulate the
container and slow the loss of any static charge.
Using Stabilizer/Conditioner
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the equipment
with its wheels on the ground.
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If you must a gasoline-dispenser nozzle, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
Important: Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to the
gas.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of varnish
deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank
Think Safety First
Shut off the engine and move the motion controls to the
PARK position.
Please read all safety instructions and symbols in the safety
section. Knowing this information could help you or
bystanders avoid injury.
Important: Do not overfill fuel tank. Fill the fuel tank
to the bottom of the filler neck. The empty space in the
tank allows the fuel to expand. Overfilling may result in
fuel leakage or damage to the engine or emission system.
DANGER
Operating the machine on wet grass or steep slopes
can cause sliding and loss of control.
1. Clean around the fuel-tank cap and remove the cap.
2. Slowly add regular, unleaded gasoline until the fuel
reaches the base of the filler neck Figure 7.
A
• Do not operate on slopes greater than 15 degrees.
• Reduce speed and use extreme caution on
slopes.
B
• Do not operate the machine near water.
DANGER
Wheels dropping over edges can cause rollovers,
which may result in serious injury, death, or
drowning.
C
Do not operate the machine near drop-offs.
DANGER
D
Operating the machine while the roll bar is down
may lead to serious injury or death in the event of a
rollover.
Always keep the roll bar in the fully raised and
locked position and use the seat belt.

Using the Side Discharge
Transporting the Machine
The mower has a hinged grass deflector that disperses
clippings to the side and down toward the turf.
Use a heavy-duty trailer or truck to transport the machine.
Ensure that the trailer or truck has all necessary brakes,
lighting, and marking as required by law. Please carefully read
all the safety instructions. Knowing this information could
help you, your family, pets, or bystanders avoid injury.
DANGER
Without a grass deflector, discharge cover, or
complete grass catcher assembly mounted in
place, you and others are exposed to blade contact
and thrown debris. Contact with rotating mower
blade(s) and thrown debris will cause injury or
death.
WARNING
Driving on the street or roadway without
turn signals, lights, reflective markings, or a
slow-moving-vehicle emblem is dangerous and can
lead to accidents, causing personal injury.
• 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.
Do not drive the machine on a public street or
roadway.
1. If you are using a trailer, connect it to the towing
vehicle and connect the safety chains.
• Never put your hands or feet under the mower.
2. If applicable, connect the trailer brakes.
• Never try to clear the discharge area or mower
blades unless you move the blade-control switch
(PTO) to the OFF position, rotate the ignition
key to the OFF position, and remove the key.
4. Shut off the engine, remove the key, set the brake, and
close the fuel valve.
• Make sure that the grass deflector is in the down
position.
5. Tie down the machine near the front caster wheels and
the rear bumper (Figure 29).
3. Load the machine onto the trailer or truck.
Figure 29
Loading the Machine
Use extreme caution when loading or unloading machines
onto a trailer or a truck. Use a full-width ramp that is wider
than the machine for this procedure. Back the machine up the
ramp and drive it forward down the ramp (Figure 30).
g028043
Figure 30
1. Back the machine up the
ramp.
25
2. Drive the machine forward
down the ramp.
Important: Do not use narrow individual ramps for
each side of the machine.
1
Ensure the ramp is long enough so that the angle with the
ground does not exceed 15 degrees (Figure 31). On flat
ground, this requires a ramp to be at least 4 times as long as
the height of the trailer or truck bed to the ground. A steeper
angle may cause mower components to get caught as the unit
moves from the ramp to the trailer or truck. Steeper angles
may also cause the machine to tip or lose control. If loading
on or near a slope, position the trailer or truck so that it is
on the down side of the slope and the ramp extends up the
slope. This will minimize the ramp angle.
WARNING
2
Loading a machine onto a trailer or truck increases
the possibility of tip-over and could cause serious
injury or death.
• Use extreme caution when operating a machine
on a ramp.
6
• Use only a full-width ramp; do not use individual
ramps for each side of the machine.
• Do not exceed a 15-degree angle between the
ramp and the ground or between the ramp and
the trailer or truck.
g027996
5
• Ensure the length of ramp is at least 4 times as
long as the height of the trailer or truck bed to
the ground. This will ensure that ramp angle
does not exceed 15 degrees on flat ground.

Stopping
Operating Tips
If you must stop the forward motion of the machine while
mowing, a clump of grass clippings may drop onto your
lawn. To avoid this, move onto a previously cut area with the
blades engaged or you can disengage the mower deck while
moving forward.
Using the Fast Throttle Setting
For best mowing and maximum air circulation, operate the
engine at the FAST position. Air is required to thoroughly cut
grass clippings, so do not set the height-of-cut so low as to
totally surround the mower in uncut grass. Always try to have
1 side of the mower free from uncut grass, which allows air
to be drawn into the mower.
Keeping 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.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that 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
15 cm (6 inches) tall, you may want to cut the lawn twice to
ensure an acceptable quality of cut.
Maintaining the Blade(s)
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. Check the mower blades after each use for sharpness,
and for any wear or damage. File down any nicks and sharpen
the blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade.
Cutting a Third of the Grass Blade
It is best to cut only about a third 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.
Alternating the Mowing Direction
Alternate the mowing direction to keep the grass standing
straight. This also helps disperse clippings which enhances
decomposition and fertilization.
Mowing at Correct Intervals
Grass grows at different rates at different times of the year.
To maintain the same cutting height, 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.
Using a Slower Cutting Speed
To improve cut quality, use a slower ground speed in certain
conditions.
Avoiding Cutting Too Low
When mowing uneven turf, raise the cutting height to avoid
scalping the turf.
Cutting 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.

Mower Deck
Maintenance
Servicing the Cutting Blades
Maintain sharp blades throughout the cutting season, because
sharp blades cut 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.
Figure 54
Check the cutter blades daily for sharpness, and for any
wear or damage. File down any nicks and sharpen the
blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade. For
convenient sharpening and replacement, you may want to
keep extra blades on hand.

Owner Responsibilities
You must maintain your Toro Product by following the maintenance

Instructions for Obtaining Warranty Service
If you think that your Toro Product contains a defect in materials or
workmanship, follow this procedure:
All repairs covered by these warranties must be performed by an Authorized
Toro Service Dealer using Toro approved replacement parts.
Neither The Toro Company nor Toro Warranty Company is liable for
indirect, incidental or consequential damages in connection with the
use of the Toro Products covered by this warranty, including any
cost or expense of providing substitute equipment or service during
reasonable periods of malfunction or non-use pending completion of
repairs under this warranty.
All implied warranties of merchantability (that the product is fit for
ordinary use) and fitness for use (that the product is fit for a particular
purpose) are limited to the duration of the express warranty.
Some states do not allow exclusions of incidental or consequential
damages, or limitations on how long an implied warranty lasts, so the
above exclusions and limitations may not apply to you.
This warranty gives you specific legal rights, and you may also have other
rights which vary from state to state.
Countries Other than the United States or Canada
This warranty is not valid in Mexico. Customers who have purchased Toro products outside the United States or Canada should contact their Toro
Distributor (Dealer) to obtain guarantee policies for your country, province, or state. If for any reason you are dissatisfied with your Distributor's service or
have difficulty obtaining guarantee information, contact the Toro importer. If all other remedies fail, you may contact us at Toro Warranty Company.
Australian Consumer Law: Australian customers will find details relating to the Australian Consumer Law either inside the box or at your local Toro
Dealer.
