Operating Instructions
Beginning Recommendations are:
♦ Learn operation of the mower in an open
area away from buildings, fences, and ob-
structions. Learn operation on flat ground
BEFORE operating on slopes.
♦ Start maneuvering the mower with SLOW
engine speed and SLOW Forward Speed
Control setting until familiar with all operat-
ing characteristics.
♦ Remember it is not necessary to hold the
steering levers forward (a unique Walker
feature); always PULL on the levers for
steering or for reverse motion of the mower.
♦ Learn to operate the mower with your left
hand on the steering levers and right hand on
Forward Speed Control.
hands on the steering levers tends to cause
overcontrol.
♦ Learn to operate the steering levers with
smooth action. Jerky movements are hard
on the transmission and lawn. For sharp
turns, do not allow the inside wheel to stop
and twist on the grass. Pull the steering le-
ver controlling the inside wheel into reverse
for a smooth "rolling" turn (one wheel roll-
ing forward while the other rolls backward).
♦ Practice maneuvering the mower until
you can make it go exactly where you are
aiming.
♦ Remember, for an emergency stop, or in
case of loss of control, machine movement
can always be stopped quickly by pulling
the Forward Speed Control into the NEU-
TRAL-PARK position.
1. Move the FSC out of NEUTRAL-PARK position
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).
The use of two
WARNING
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. When the 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.
NOTE: If the FSC lever will not stay in the
selected position, the friction lock needs to be
adjusted. Contact your Walker Dealer.
CAUTION
A safety interlock switch (seat switch) will
cause the engine to stop if the FSC is out
of the NEUTRAL-PARK position and the
operator is not in the seat. The function of
this switch should be checked by the op-
erator raising off the seat with the tractor
moving forward (allow 1 to 1-1/2 seconds
off the seat for the time delay function);
the engine should stop. If the safety sys-
tem 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.
2. Steer by pulling the lever on the side of desired
direction of turn, e.g., pull the LH lever to turn
left. To minimize the possibility of overcontrol,
use only one hand on both steering levers.
