B27i
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; the engine should stop. In each
case, if the safety sys tem is not working, it
should be repaired or replaced before op-
erating 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 Transmis-
sion Control Step 6 - Forward Speed Control
Friction Adjustment on page 66.
Forward Speed Control
(FSC)
Correct Operator Hand Position on the Controls
3. Reverse direction of the mower by pulling both
levers backward.
NOTE: Smooth action on the steering levers
will produce smooth mower operation.
Remem ber to keep the engine and ground
speed slow until learning the control response.
CAUTION
Pull Steering
Levers With
Left Hand
Keep Feet On Footrest
When Moving
WARNING
When moving forward, DO NOT suddenly
put the tractor in reverse by rapidly pulling
on the steering levers, especially when go-
ing downhill, as this can lift the tractor tail
wheel off the ground and set up a bucking
motion due to operator overcontrol.
bucking does occur, immediately stop the
bucking action by pulling the Forward
Speed Control (FSC) lever into the NEU-
TRAL-PARK position.
4. The FSC may be adjusted forward for faster
ground speed and backward for slower ground
speed. When mowing, ground speed should
be adjusted to match the load on the cutter
blades, i.e., as the engine pulls down in heavy
cutting, pull back on the FSC lever to reduce
ground speed. Adjusting ground speed helps
maintain a balance between engine power and
blade speed for high-quality cutting action.
5. Stop ground travel by pulling both steering
le vers backward to the NEUTRAL position
(trac tor not moving) and then moving the FSC
lever to the NEUTRAL-PARK position.
NOTE: If the tractor creeps forward or back -
ward with the FSC lever in the NEUTRAL-
PARK position, the transmission control needs
to be adjusted. For details refer to Adjust-
ments for Transmission Control Step 3 - Neu-
tral Function Adjustment on page 65.
WARNING
If 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, immediately (1) Re-
lease the steering levers and simultane-
ously (2) Move the FSC to the NEUTRAL-
PARK position. When the machine is
stopped or moving slowly, engage the
parking brake.
NOTE: This is exactly the same procedure used
to normally stop and park the machine.
