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 Cub Cadet 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 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 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 9.
Operator must be sitting in the tractor seat.
Engage the parking brake. Refer to Figure 9.
Make certain the PTO switch is in the disen-
gaged (down) position. Refer to Figure 9.
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.
Figure 9
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 5 seconds at a time. If the
engine does not start within this time, turn the key
to “OFF” and wait at least 15 seconds 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 start-
ing 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.
