• 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: For personal safety, the
operator must be sitting in the tractor
seat when 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.
• 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.
• Model RZT42 ONLY
1. Move the throttle control lever fully forward
into the "CHOKE" position. NOTE: If the
engine is warmed up, it may not be necessary
to place the throttle control in the choke
position.
2. Turn the ignition key clockwise to the "START"
position and release it as soon as the engine
starts; however, do not crank the engine
continuously for more than 5 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.
3. As the engine warms up, gradually pull the
throttle control lever rearward past the choke
detent position. Do not use the choke to enrich
the fuel mixture, except as necessary to start
the engine.
