to the desired forward speed. DO NOT hold
for ward on steering levers. It is not necessary
to hold the FSC lever in position since a friction
lock maintains the selected lever position (and
forward travel speed).
In case the transmission drive belt breaks
during operation, and if the machine is on
a slope, the machine will freewheel down
the slope. To maintain control, immedi-
ately (1) Release the steering levers and
simultaneously (2) Move the FSC to the
NEUTRAL-PARK position.
ma chine is stopped or moving slowly,
en gage the parking brake.
NOTE: This is exactly the same procedure
used to normally stop and park the machine.
An operator presence switch (seat switch)
will cause the engine to stop if the parking
brake is in the DISENGAGED position and/
or the FSC is out of the NEUTRAL-PARK
position (tractor stationary or moving for-
ward) and the operator is not in the seat.
The function of this switch should be
checked by the op erator raising off the
seat, first with the parking brake DISEN-
GAGED, and then with the tractor moving
forward (allow 1/2 second "off the seat" for
the time delay function); the engine should
stop. In each case, if the safety sys tem is
not working, it should be repaired or re-
placed before operating the mower. DO
NOT disconnect the safety switches; they
are for the operator's protection.
NOTE: If the FSC lever will not stay in the
selected position, the friction lock needs to be
adjusted. Refer to ADJUSTMENTS for Step 7 -
Forward Speed Control Friction Adjustment in
the Maintenance Instructions.
