Or rough terrain. DO NOT Operate the machine on
hillsides or slopes exceeding 15° (27% grade). If
Safety is in doubt— STAY OFF THE SLOPE.
44. Reduce speed and exercise extreme caution on
siopes above 10° (18% grade) to prevent tipping or
loss of control. Never mow uphill on these
slopes —mow downhill only. if you must climb a steep
hill, back the machine up the hill, and drive the
machine forward down the hill, keeping the vehicle in
gear. If necessary to tum on hill, always turn downhill.
45. Mow up and down the face of slopes greater than
5° (9% grade), never across the face. Be especially
cautious when changing directions on all slopes.
46. Operate your machine Smoothly and at a ground
Speed slow enough to ensure complete control.
Avoid erratic Operation and excessive Speed.

RIDING MOWER CONTROLS
1. Throttle/Choke Control
The throttle/choke control is on the left side on the
control panel. Raise the lever to the detent near the
top of the slot to operate the rider. Raise the lever all
the way up past the detent to start the engine. Lower
the lever before shutting the engine off.
2. Ignition Switch (Electric Start)
The ignition switch is on the left side of the rider on the
control panel. The ignition switch has three positions:
(1) OFF, (2) RUN, (3) START.
To start the engine, tum the key all the way to START.
Release the key when the engine starts — it will
automatically return to the RUN position.
Tum the switch to the OFF position to stop the engine.
3. Brake Pedal
The brake pedal is at the front of the rider just to the
right of the steering console. Pushing the pedal down
declutches the drive belt, disconnects the engine from
the transmission, and applies the brake. Always
release the pedal slowly when engaging the clutch.
Also, always depress the pedal when shifting the
transmission into or out of gear and when starting the
engine.
4. Parking Brake Lever
The parking brake is on the frame in front of the seat.
To engage the parking brake lever, first press the foot
brake solidly; then move the parking brake lever to the
left and into the notch to lock the brake pedal.
To release the parking brake, push down on the foot
brake. The parking brake lever will return to the
disengaged position when you press the foot brake.
5. Gear Shift Lever
The gear shift lever is on the rider's right side. Select
any forward or reverse speeds by moving the lever to
the position shown on the shift decal. The shift lever
must be in NEUTRAL to start the engine.
6. PTO (Power Take-Off) Clutch Lever
The PTO clutch tever is on the rider's left side on the
control panel. It engages and disengages the
power-driven attachments. To engage the PTO, move
the lever forward. To disengage the PTO, move the
lever back. The PTO lever must be in the disengaged
position to start the engine. If you leave the seat while
the PTO is engaged, a seat switch will automatically
shut off the engine.
7. Fuel Tank And Vent Shutoff Valves
A fuel shut-off valve is at the bottom of the fuel tank.
A second shut-off valve is in the fuel cap. It closes
the vent hole in the cap. Both valves must be closed
before standing the rider on end. Refer to instructions
in the Maintaining Your Rider section of this guide for
more information.
8. Mower Height Control Lever
The mower height control lever is at the left rear of the
mower. Cutting height is adjustable in 1/2 in. (1.3 cm)
steps.
OPERATING YOUR RIDER
SAFETY INTERLOCK SYSTEM
Each rider has four interlock switches. The switches
are actuated by the PTO clutch lever, the gear shift
lever, and the seat. The PTO and gear shift switches
prevent the rider from starting if the mower is engaged
or the transmission is in gear. During use, seat
switches will shut off the engine if you rise off the seat
while the PTO is engaged.
Besides switches, the mower discharge chute (or
bagger discharge elbow) has a special stud for
attaching a mower interlock wire. This wire must be
connected to the stud or the rider will not start. This is
to prevent the rider from operating unless the
discharge chute or elbow is installed.
If the rider will not start, check that the transmission IS
in NEUTRAL, the mower is disengaged, and the
mower interlock wire is connected. The rider will not
start unless these controls are in their correct
positions.
The safety interlock system must be tested
periodically. To test the safety interlock system, check
the following responses. (If your system doesn't
respond as described, have an Authorized TORO
Wheel Horse Dealer immediately repair the system.)
1. The engine should NOT start if:
A. The transmission is NOT in NEUTRAL.
B. The PTO lever is engaged.
C. The mower interlock wire is disconnected
from the discharge chute or elbow.
2. With the engine running, test the operator seat
switch by engaging the PTO and rising off the seat.
The engine should shut off.
" CHECK THE FUEL
Fill the tank with a good grade (85 octane minimum) of
regular gasoline. You may use leaded or unleaded
regular gasoline. However, DO NOT MIX regular and
unleaded gasolines. Also, do not mix oil with
gasoline. We do not recommend using gaschol fuel.
We recommend leaded regular gasoline for first 25
hours of operation while the piston rings are seating,
and unleaded fuel after that. Unleaded fuel will
reduce the build-up of combustion deposits in the
engine and contribute to long valve life.
A DANGER
e Gasoline is highly flammable, use caution
when storing or handling it.
® Do not fill the fuel tank while the engine Is
running, hot, or when machine is in an
enclosed area. Vapors may build up and
be ignited by a spark or flame source
many meters (feet) away.
* DO NOT SMOKE while filling the tank.
® Always fill the fuel tank outside and wipe
up any spilled fuel before starting the
engine.
® To prevent spilling fuel, use a funnel or
Spout and fill the tank to about 25 mm
(1 in.) below the filler hole. DO NOT
OVERFILL.
® Use gasoline for the engine only, not for
any other purpose.
e Store gasoline in a clean, safety approved
container and keep the container capped.
® Keep gasoline in a cool, well-ventilated
place. Never store gasoline in an
enclosed area such as a hot storage
shed.
e Never buy more than 30 days’ supply to
assure volatility.
® Because many children like the smell of
gasoline, keep it out of their reach
because the fumes are explosive and
dangerous to inhale.
OPERATING YOUR RIDER
y” CHECK THE OIL
To protect your rider's engine, check its oil level
before each use. You will find complete information
on recommended oils and how to check the oil level
in the “Maintaining Your Rider” section.
ENGINE OPERATION
A CAUTION
Before starting the engine, become familiar
with all controls. Read this Operator's Guide
thoroughiy. Also, always check the engine's
oil level before starting the engine.
A WARNING
Avoid inhaling exhaust gases because they
contain carbon monoxide gas, which is
colorless and odorless. Carbon monoxide is
a dangerous gas that can cause
unconsciousness and is potentially lethal. Do
not run the engine in confined areas such as a
closed garage.
STARTING THE ENGINE
Because of a built-in safety interlock system, your
rider will not start unless the transmission is in
NEUTRAL and the PTO is disengaged. To start the
engine, put the transmission in NEUTRAL and
disengage the mower.
A CAUTION
Always lock the parking brake lever before
starting the engine.
Turn the key clockwise until the starter engages.
When the engine starts, release the key. The switch is
spring loaded and will return to the RUN position
automatically.
If the engine fails to start after 30 seconds of
continuous cranking, turn the key to OFF and allow the
starter motor to cool. Check for the cause of hard
starting; consult the troubleshooting check list.
Once the engine starts, lower the throttle to the
detented, full-throttle (OPERATE) position.
STOPPING THE ENGINE
To stop the engine, move the throttle lever to the idle
position and turn the ignition key to OFF. If the engine
has been working hard or is hot, allow it to idle a short
time before tuming off the key. This will help cool the
engine before stopping.
Note: In an emergency, the engine may be stopped
by tuming the ignition key to the OFF position.
A CAUTION
Always remove the key and set the parking
brake when leaving the rider unattended, even
if just for a few minutes. Prevent accidents;
don’t give children or unauthorized persons
an opportunity to operate this machine.
THROTTLE CONTROL
The throttle control regulates the engine speed as
measured in RPM (Revolutions Per Minute). This
control should not be used to regulate the rider's
ground speed.
Always operate the rider with the throttle control set at
full speed. Your rider's engine was designed with a
special governor that limits its RPM. Unlike an
automobile, this governor allows the engine to operate
most efficiently at a set speed and protects it from
damage caused by excessive RPM.
Use the choke when starting a cold engine. The
choke control activates a “butterfly” valve in the
carburetor. When the choke is partially or completely
closed, less air is admitted to the engine. This
creates a higher fuel-to-air (richer) mixture that is
easier for a cold engine to ignite. Warm engines may
not need choking.
OPERATING YOUR RIDER
TO GO FORWARD OR REVERSE
The rider has a reverse “lock out” that helps prevent
shifting into reverse accidentally. To shift the rider into
reverse, push the lever to the right, then move it back
into the reverse position.
With the engine running, depress the brake pedal.
Move the gear shift lever to the desired speed forward
or to reverse. The shift plate decal identifies various
Speeds. Slowly release the brake pedal. As you
release the brake pedal, the rider will begin to move.
A CAUTION
Always release the brake pedal slowly.
Sudden starts can damage equipment and
cause loss of operator control.
TO CHANGE SPEED OR DIRECTION
When changing ground speed or direction, always
bring the rider to a complete stop by depressing the
brake pedal.
IMPORTANT: Never try to shift gears with the unit in
motion. Severe transmission damage may result.
Change gears as desired. The specification section in
the front of this guide shows the ground speed for
each gear. It is not necessary or recommended to
shift “up” or “down” through gears with the rider in
motion. The rider has sufficient power to move out in
any gear. However, If the rider will not move out in a
selected gear with a heavy load attached, a lower
gear should be used.
TO STOP
To stop the rider, press the brake pedal. Always
engage the parking brake before leaving the rider.
10
OPERATING WITH A MOWER
A CAUTION
Read the guides provided with attachments
before operating. These guides give a more
detailed description of operation. Famillarize
yourself thoroughly with equipment before
using it.
AVOID CONTACT WITH THE
ROTATING BLADE:
e Stop the blade before putting your foot on
the ground or leaving the seat.
e Be sure the blade has stopped before you
try to unclog the discharge or place your
hands or feet near the bottom of the blade
housing.
e Never start the blade unless you are
correctly seated on the machine.
® Stop the blade and the engine, set the
parking brake and remove the key when
leaving the machine.
Keep all shields and the mower discharge
chute in place. Never try to clear the
discharge areas or the mower blade without
disengaging the mower and removing the
ignition key.
IMPORTANT: Each time you install the mower,
check the PTO clutch and brake operation.
For best operation on normal lawns, operate the
engine at full throttle: control the ground speed with
the transmission.
Excessive ground Speed often causes uneven cutting.
Correct it by shifting into a lower gear to reduce the
ground speed.
Typical lawns are usually cut at a height between 2
and 3 in. (5-7.7 cm). Cut tall grass and weeds with
the mower in its highest position, then make a second
pass cutting to the height desired. Always keep the
mower blade sharp.
OPERATING YOUR RIDER
Mowing Speed
The mower is designed to operate most efficiently at
its maximum blade speed. The gear to use for
mowing is the one that will allow the mower blade to
maintain maximum speed while mowing across turf.
For best cutting results on most lawns, operate the
rider in second, third or fourth gear. For cutting tall
grass, grass that is heavy with moisture, or when
moving uphill, use first or second gear. If the ground
speed is too fast, or the blade speed is too slow,
mowing will be uneven because the mower blade
won't be able to lift the grass blades into cutting
position as the mower passes over them. Use first
gear for trimming operations.
Mowing Height
You probably know the best cutting height for your
lawn from previous experience. The first time you use
your new rider, set the mower to cut a little higher than
you have cut in the past. This will help you to decide
the best approach to uneven areas and to make sure
a wider cut does not scalp high spots.
Very tall or wet grass can be cut without difficulty by
using a little care. Set the mower in its highest cutting
position and enter the area in first gear. If necessary,
take a cut one-half the width of the mower,
overlapping previously cut area on each pass. Then,
with the mower set to the desired height, do a finish
cut over entire area. Remember, a sharp blade
produces cleaner cuts and uses less power.
To help keep a green lawn, never mow more than one
third off the height of the grass, or a maximum of one
inch (2.5 cm), in ane mowing.
For best appearance, cut the grass in the afternoon or
early evening (in daylight) when it is free of external
moisture.
Mowing Pattern
The size and type of area determine the best mowing
pattern to use. Also consider obstructions such as
trees, fences and buildings. Where possible, make
one or two passes in a clockwise direction around the
outside of the area to keep cut grass off fences and
walks. The rest of the mowing should be done in a
counter-clockwise direction to disperse the clippings
on the cut area.
When possible, keep the mower's left side toward
trees, posts, or other obstacles on the first pass
around obstacles to minimize hand trimming.
On moderate-sized, frequently mowed lawns where
grass is light and dry, it is sometimes practical to mow
in a clock-wise direction to throw the clippings toward
the lawn's center for easy pickup and removal.

ATTACHMENTS
Many attachments simply use the rider as a towing
vehicie. They are attached or removed from the rider
by installing or removing a single drawbar hitch pin.
Some attachments are powered by a separate
gasoline engine, some are “ground driven” and some
are simply towed, such as a lawn sweeper or dump
cart. In any case, approach all attachments with the
same caution you should give any mechanical device.
Always read each “Operating Instruction Guide”
carefully before using the attachment. Keep children
and pets away from the operating vehicle. Never
allow unauthorized personnel to operate the
equipment.
DUMP CART LOAD LIMITS
Load limits have been set for safe braking on siopes.
We recommend you observe the following load limits
when using the rider with a dump cart.
100-Series - 150 Ibs (69 kg)
OPERATING WITH THE REAR BAGGER
The optional rear-mount grass bag can affect the
riders operation. Because of the bagger's added
weight and the extra power required, operate the rider
in a lower transmission gear.
A CAUTION
Be careful when maneuvering with the grass
catcher because it may adversely affect front-
to-rear stability. Under normal use, the grass
catcher bag material will deteriorate and wear.
Check it often for possible replacement.

MAINTAINING YOUR RIDER
THE ELECTRICAL SYSTEM
An alternator charges the rider's battery. The
alternator charging system usually needs no service,
other than periodically checking that all exposed
wiring and electrical connections on the rider are
Clean, tight and in good conditions.
IMPORTANT: Correct polarity is critical with an
alternator charging system. Always disconnect the
battery ground cable (negative) before working on
any part of electrical system. Make sure to
connect all components correctly before
reconnecting the ground cable (negative) or you
may damage the alternator system components.

Battery
A WARNING
e When servicing the battery or any other
part of the electrical system, or if the
battery must be removed for any reason,
always disconnect the NEGATIVE ground
cable FIRST and reconnect it LAST to
avoid electrical shorts:
e Wear safety goggles and rubber gloves
when working with electrolyte.
e Charge the battery in a well-ventilated
location so that the gasses produced by
the charging can escape.
® Because gasses are explosive, keep open
flames and electrical sparks away from
the battery.
® Do not smoke.
e Nausea may result if the gasses are
inhaled. Before connecting or
disconnecting charger leads from the
battery, unplug the charger from the
electrical outlet.
® In an accident, flush the affected area
Immediately with a solution of one part
baking soda to four parts water. Notify
physician immediately. If baking soda is
not immediately available, flush the
affected area with water. Notify physician
immediately.
Maintain the electrolyte level above the plates in each
cell by adding distilled water. The best time to add
water is just before operating the rider so the water
will mix with solution. Do not overfill the battery.
Electrolyte solution is corrosive and overfilling can
damage surrounding metal parts. Maintain the battery
at a 1.265 specific gravity charge.
If the battery has been removed from the rider for
servicing, take care to connect cables to the battery
exactly as they were before removal.
For longest service life, the battery should be kept
Clean by wiping it with a paper towel. Any corrosion
around the battery terminals should be removed by
applying a solution of one part baking soda to four
parts water. Apply a light coating of grease or
petroleum jelly to all exposed terminal surfaces to
prevent corrosion.
IMPORTANT: At temperatures below 32° F (0° С),
a full charge state must be maintained to prevent
cell electrolyte from freezing and causing
permanent battery damage.

TRANSMISSION
The mechanical transmission is packed with grease
and is a sealed unit. No periodic lubricant checks are
required; changing the lubricant is not necessary
except for major service.
CHASSIS LUBRICATION
The front wheels and front axle spindles have zerk
fittings. Before using a grease gun, clean the zerk
fittings carefully to avoid forcing dirt into the fitting.
After greasing, wipe off any excess grease. Use a
general purpose grease (lithium base) to lubricate the
rider.
Lubricate the wheel bearings after each 25 hours of
operation. Grease the mower-blade spindle and
lubricate all other pivoting arms and levers at same
time with light machine oil applied directly to wear
surfaces.
