OPERATION, cont'd
Before Operating Tractor
• Before operation, refer to Maintenance Schedule chart located in this manual for
regularly scheduled service items.
• This engine is certified to operate only on clean, fresh, unleaded gasoline. Fill only
with clean, fresh, unleaded gasoline with a pump sticker octane rating of 87 or higher.
• Do not use gasoline left over from the previous season, to minimize gum deposits in
the fuel system.
• Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is an approved
fuel. Other gasoline/alcohol blends are not approved.
• Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum
of 15% MTBE by volume) are approved fuels. Other gasoline/ether blends are
not approved.
Safety Interlock System
WARNING: Do NOT operate the tractor if the safety interlock system is
malfunctioning. This system was designed for your safety and protection.
This tractor is equipped with a safety interlock system for the protection of the operator.
If the interlock system should ever malfunction, do not operate the tractor. Contact an
authorized service dealer.
• The safety interlock system prevents the engine from cranking or starting unless the
parking brake is engaged, and the PTO switch is in the DISENGAGED (OFF) position.
• The engine will automatically shut OFF if the operator leaves the seat before
engaging the parking brake.
• The engine will automatically shut OFF if the operator leaves the tractor's seat with
the PTO switch in the ENGAGED (ON) position, regardless of whether the parking
brake is engaged.
Checking the safety interlock Circuits
Periodically check the safety interlock circuits to ensure they are working properly. If a
safety circuit is not working as designed, contact a service dealer to have the tractor
inspected. Do NOT operate the tractor if any safety circuit is not functioning properly. To
check the safety circuits, proceed as follows:
1. Pull the PTO upward to the ENGAGED (ON) position. Momentarily turn the ignition
switch to the START position; the engine should not crank.
2. With the tractor running move both lapbar drive control levers fully inward in the
neutral position; then lift upward from the operator's seat. The engine should stop.
3. With both lapbar drive control levers fully outward in the parking brake engaged
position, engage the PTO. Lift upward from the operator's seat; the engine
should stop.
Starting the Engine
CAUTION: The operator should be sitting in the tractor seat when starting
the engine.
1. Operator should be sitting
in the tractor seat with the
Outward & in the Park Brake Position
lapbar drive control levers
fully out and in the park
position. See Figure 25.
Refer to Practice Operation
for further instructions.
2. Make certain the PTO
is in the "OFF" position.
Move the choke control or
throttle/choke control into
the full choke position.
Move the throttle control
to midway between its
slow and fast positions on
models with a separate
choke control.
nOTE: If the engine is warmed up, it may not be necessary to choke the engine.
3. Turn the key clockwise to the START position. After the engine starts, release the key.
It will return to the RUN position.
CAUTION: Do not hold the key in the START position for longer than ten
seconds at a time. Doing so may cause damage to engine's electric starter.
4. As the engine warms up, gradually pull the throttle/choke control lever rearward past
the choke detent position or slowly disengage the choke on models with a separate
choke. Do not use the choke position to enrich the fuel mixture, except as necessary
to start the engine.
5. Allow the engine to run for a few minutes at mid-throttle before putting the engine
under load.

6. Observe the hour meter/indicator panel. If the battery indicator light or oil pressure
light come on, immediately stop the engine. Have the tractor inspected by an
authorized service dealer.
Cold Weather Starting
When starting the engine at temperatures near or below freezing, ensure the correct
viscosity motor oil is used in the engine and the battery is fully charged. Start the engine
as follows:
1. Be sure the battery is in good condition. A warm battery has much more starting
capacity than a cold battery.
2. Use fresh winter grade fuel. Winter grade gasoline has higher volatility to improve
starting. Do not use gasoline left over from summer.
3. Follow the previous instruction for Starting the Engine.
Using Jumper Cables to Start Engine
WARNING: Batteries contain sulfuric acid and produce explosive gases.
Make certain the area is well ventilated, wear gloves and eye protection,
and avoid sparks or flames near the battery.
If the battery charge is not sufficient to crank the engine, recharge the battery. If a battery
charger is unavailable and the tractor must be started, the aid of a booster battery will be
necessary. Connect the booster battery as follows:
1. Connect the end of one cable to the disabled tractor battery's positive terminal; then
connect the other end of that cable to the booster battery's positive terminal.
2. Connect one end of the other cable to the booster battery's negative terminal; then
connect the other end of that cable to the frame of the disabled tractor, as far from
the battery as possible.
3. Start the disabled tractor following the normal starting instructions previously
provided; then disconnect the jumper cables in the exact reverse order of
their connection.
4. Have the tractor's electrical system checked and repaired as soon as possible to
eliminate the need for jump starting.
Stopping the Engine
1. Disengage the PTO.
2. Move the RH and LH lapbar drive control levers fully outward into the Park Brake
engaged position.
3. Move the throttle control to the FAST position.
4. Turn the key to the STOP position and remove the key from the ignition module.
nOTE: Always remove the key from the ignition module to prevent accidental starting or
battery discharge if the equipment is left unattended.
Practice Operation (Initial use)
Operating a zero-turn tractor is not like operating a conventional type riding tractor.
Although and because a zero-turn tractor is more maneuverable, getting used to
operating the lapbar drive control levers takes some practice.
It is strongly recommended that you locate a reasonably large, level and open "practice
area" where there are no obstructions, pedestrians or animals. You should practice
operating the tractor for a minimum of 30 minutes.
Carefully move (or have moved) the tractor to the practice area. When performing the
practice session, the PTO should not be engaged. While practicing, operate the tractor at
approximately 1⁄2-3⁄4 throttle and at less than full speed in both forward and reverse.
Carefully practice maneuvering the tractor using the instructions in the following section
Driving the Tractor. Practice until you are confident that you can safely operate the tractor.
Driving the Tractor
WARNING: Keep all movement
of the lapbar drive control
levers slow and smooth. Abrupt
movement of the control levers
can affect the stability of the
tractor and could cause the
tractor to flip over, which may
result in serious injury or death to
the operator.
1. Adjust the operator's seat to the most
comfortable position that allows
you to operate the controls. See seat
adjustment in the Assembly section.
2. Move the RH and LH lapbar drive
control levers inward in the neutral
position which also disengages the
parking brake. Refer to Figure 26.
