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 Transmis-
sion Control Step 7 - Forward Speed Control

Steer by pulling the lever on the side of de-
sired direction of turn, e.g., pull the LH lever to
turn left. To minimize the possibility of over-
control, use only one hand on both steering
levers.

GETTING STARTED RECOMMENDATIONS:
♦
Learn operation of the mower in an
open area away from buildings, fenc-
es, and ob structions. Learn opera-
tion on flat ground BEFORE operat-
ing on slopes.
♦
Start maneuvering the mower with
SLOW engine speed and SLOW For-
ward Speed Control setting until fa-
miliar with all operat ing characteris-
tics.
♦
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 mo-
tion of the mower.
♦
Learn to operate the mower with your
left hand on the steering levers and
right hand on Forward Speed Con-
trol. The use of two hands on the
steering levers tends to cause over-
control.
♦
Learn to operate the steering levers
with smooth action.
ments are hard on the transmission
and lawn. For sharp turns, do not al-
low the inside wheel to stop and twist
on the grass. Pull the steering le ver
controlling the inside wheel into re-
verse for a smooth "rolling" turn (one
wheel roll ing forward while the other
rolls backward).
♦
Practice maneuvering the mower un-
til 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 po-
sition.
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.
