Headlights (Not Shown)
On some tractors the lights are ON whenever the ignition key is rotated out of the STOP
position. The lights turn OFF when the ignition key is moved to the STOP position.
On some tractors the lights are ON only while the engine is running. Turning the tractor
OFF will turn the lights OFF.
Operation
Before Operating Your 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 safety 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 or the operator is in the seat and the brake pedal
is fully depressed, with the PTO (Blade Engage) lever 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 (Blade Engage) lever in the ENGAGED (ON) position, regardless of
whether the parking brake is engaged.
• With the ignition key in the NORMAL DRIVING MODE position, the engine will
automatically shut OFF if the PTO (Blade Engage) lever is moved into the engaged
(ON) position with the speed control in REVERSE (R) position.
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 your authorized 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. With the engine off and sitting in the seat, place the PTO lever in the ENGAGED
(ON) position. Momentarily turn the ignition switch to the START position; the
engine should not crank.
2. With the tractor running, and the parking brake not engaged; lift upward from
the operator’s seat. The engine should stop.
3. With the parking brake engaged, 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. Insert the ignition key into the ignition switch.
2. Place the PTO (Blade Engage) lever in the OFF position.
3. Engage the tractor’s parking brake.
4. Push the throttle control upward. If equipped with a throttle/choke control lever,
push the throttle/choke control lever past the detent, to engage the choke.
Note: If the engine is warmed up, it may not be necessary to choke the engine.
5. Turn the ignition key clockwise to the START position. After the engine starts,
release the key. It will return to the NORMAL MOWING 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 your engine’s electric starter.
6. For models equipped with a throttle/choke control lever: as the engine warms
up, gradually pull the throttle/choke control lever rearward past the choke
detent position. Do not use the choke position to enrich the fuel mixture, except
as necessary to start the engine.
7. Allow the engine to run for a few minutes at mid-throttle before putting the
engine under load.
Note: When operating the tractor be certain that the throttle lever is always in
the FAST position.
