• 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 con-
trol 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.
STARTING THE ENGINE
WARNING: This unit is equipped with a
safety interlock system designed for the
protection of the operator. Do not oper-
ate the tractor if any part of the interlock
system is malfunctioning. Periodically
check the functions of the interlock sys-
tem for proper operation.
WARNING: For personal safety, the
operator must be sitting in the tractor
seat when starting the engine.
• Move the RH and LH drive control levers fully
outward in the neutral position. Refer to Figure
10.
• Operator must be sitting in the tractor seat.
• Engage the parking brake. Refer to Figure 10.
• Make certain the PTO switch is in the disen-
gaged (down) position. See Figure 10.

• Pull the choke control knob upward to the full
choke position. NOTE: If the engine is warmed
up, it may not be necessary to choke the engine.
• Move the throttle control to midway between its
SLOW and FAST positions.
• Turn the ignition key clockwise to the “START”
position and release it as soon as the engine
starts; however, do not crank the engine continu-
ously for more than 10 seconds at a time. If the
engine does not start within this time, turn the key
to “OFF” and wait a minute to allow the engine’s
starter motor to cool. Try again after waiting. If
after a few attempts the engine fails to start, do
not keep trying to start it with the choke closed as
this will cause flooding and make starting more
difficult.
• As the engine warms up, gradually push the
choke knob downward to open the choke. Do not
use the choke to enrich the fuel mixture, except
as necessary to start the engine.
• Allow the engine to run for a few minutes at mid
throttle before putting the engine under load.
• 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 your authorized Troy-Bilt Service
Dealer 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:
• Be sure the battery is in good condition. A warm
battery has much more starting capacity than a
cold battery.
• Use fresh winter grade fuel. Winter grade
gasoline has higher volatility to improve starting.
Do not use gasoline left over from summer.
• Follow the previous instruction for STARTING
THE ENGINE.
USING JUMPER CABLES TO START ENGINE
WARNING: Batteries contain sulfuric acid
and produce explosive gasses. 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:
LH Control Lever
Out in Neutral
Parking Brake
RH Control Lever
Out in Neutral
Engaged
Throttle Control
Pull Choke
PTO Switch in Down
(Disengaged) Position
to "MID" position
