Operating Instructions
28
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.
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
levers backward to the
NEUTRAL-PARK
posi-
tion (tractor 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. Contact your Walker Dealer.
ENGAGING THE MOWER
1.
Set the engine throttle at about 1/3 speed.
Do
not attempt to engage the blade clutch at
high engine speeds.
This will drastically
shorten drive belt life. Use only moderate
engine speed when engaging the blade clutch.
2.
Engage the mechanical clutch by pulling the
blade clutch lever forward
quickly.
DO NOT
engage slowly. For disengagement, push the
blade clutch lever backward
quickly.
IMPORTANT: DO NOT
engage the blade clutch
when transporting the mower across drives, side-
walks, loose materials, etc.
DO NOT engage the
blade clutch with the PTO shaft disconnected
(the mower deck removed from tractor).

CAUTION
A safety interlock switch (PTO switch) will
cause the engine to stop if the PTO is in
the engaged position and the operator is
not in the seat. The function of this switch
should be checked by the operator
raising off the seat with the PTO engaged
(allow 1 to 1-1/2 seconds off the seat for
the time delay function); the engine
should stop. If the safety system is not
working, it should be repaired or replaced
before operating the mower. DO NOT
disconnect the safety switches; they are
for the operator's protection.
