General Safety
RECEIVE INSTRUCTION — Entirely read this operator’s •
manual. Learn to operate this machine SAFELY. Do not risk
INJURY or DEATH. Allow only those who have become
competent in its usage to operate this tractor.
Before starting the engine or beginning operation, be
•
familiar with the controls. The operator should be in the
operator’s seat. The PTO switch must be in the disengaged
position, the parking brake engaged, and the RH and LH
drive control levers moved fully outward in the neutral
position.
Keep all shields in place. Keep away from moving parts.
•
NO RIDERS! Keep all people and pets a safe distance away. •
Look behind and down to both sides of the tractor before
and while backing up.
DO NOT direct the mower discharge at people.
•
Avoid slopes where possible. Never operate on slopes •
greater than 15°. Slopes with a greater incline present
dangerous operating conditions. Tractors can be rolled
over.
Before leaving the operator’s seat: Shut off the PTO, move
•
the RH and LH drive control levers fully outward in the
neutral position, engage the parking brake, shut off the
engine and remove the ignition key. Wait for all movement
to stop before servicing or cleaning.
Operate the drive control levers smoothly and avoid
•
any sudden movements of the levers when starting and
stopping. Keep a firm grip on the control levers.
Be careful when operating near roadways. Stop the tractor
•
motion and wait for vehicles to pass before operating
along the road.
Do not operate the tractor with the mower deck removed.
•
Removal of the deck will change the balance of the tractor,
and could contribute to a tractor rollover.
Avoid operation on traction surfaces that are unstable; use
•
extreme caution if the surface is slippery.
Slow down before turning and come to a complete stop
•
before any zero turn maneuver.
Do not stop the tractor or park the tractor over
•
combustible materials such as dry grass, leaves, debris, etc.
Do not fill the fuel tank when the engine is running or
•
while the engine is hot. Allow the engine several minutes
to cool before refueling. Tighten the fuel cap securely.
Before Operating Your Tractor
Before you operate the tractor, study this manual carefully •
to familiarize yourself with the operation of all the
instruments and controls. It has been prepared to help you
operate and maintain your tractor efficiently.
This engine is certified to operate only on clean, fresh,
•
unleaded regular gasoline. For best results, fill the fuel
tank with only clean, fresh, unleaded gasoline with a pump
sticker octane rating of 87 or higher.
Unleaded gasoline is recommended because it leaves less
•
combustion chamber deposits and reduces harmful exhaust
emissions. Leaded gasoline is not recommended and must
not be used where exhaust emissions are regulated.
NOTE: Purchase gasoline in small quantities. 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.
Check the engine oil level.
•
Clean the air cleaner element if necessary. •
Check the tire inflation pressures. •
Adjust the seat for operator’s maximum comfort, visibility •
and for maintaining complete control of the tractor.
Safety Interlock System
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 your authorized
Troy-Bilt Dealer.
The safety interlock system prevents the engine from •
cranking or starting unless the RH and LH drive control
levers are moved fully outward in the neutral position, the
parking brake is engaged, and the PTO is disengaged.
To avoid sudden movement when disengaging the parking
•
brake, the safety interlock system will shut off the engine
if the RH and/or LH drive control levers are moved to a
position other than the fully out in the neutral position
when the parking brake is engaged.
The safety interlock system will shut off the engine if the
•
operator leaves the seat before engaging the parking brake.
The safety interlock system will shut off the engine if the
•
operator leaves the seat with the PTO engaged, regardless
of whether the parking brake is engaged.
NOTE: The PTO switch must be moved to the “OFF”
position to restart the engine.
The safety interlock system will shut off the PTO and the
•
mower blades will stop if both drive control levers are
moved into the reverse position. The PTO will re-engage
when one or both of the levers are moved back to the
neutral or forward position.
