Operating Instructions
30
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).
WARNING
In case either of the transmission drive
belts break during operation, and if the
machine is on a slope, the machine will
freewheel down the slope. To maintain
control, immediately (1) Release the
steering levers and simultaneously (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.
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 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. Contact your Walker dealer.
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.
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. The use of two
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.
