Operating Instructions

3. After the engine starts, make sure the oil pres-
sure light goes off. If not, stop the engine imme-
diately and find the cause of the problem. Make
sure the oil pressure light is off prior to engaging
the mower blades and beginning operation.
4. For Model MT and MTL, gradually move the
choke to the OFF position, keeping enough
choke on to allow the engine to run smoothly
as it warms up. As soon as possible, move the
choke to the OFF position.
IMPORTANT: For Model MT and MTL, make
sure the choke is in the OFF position during nor-
mal engine operation; running with the choke in
the ON position CAN damage the engine.
ADJUSTING GROUND SPEED AND STEERING
IMPORTANT: If the DSD52 or DSD62 Mower deck
is installed on the tractor, make sure the dolly wheel
is retracted BEFORE moving.
1. Move the FSC out of NEUTRAL-PARK
position to the desired forward speed. DO
NOT hold forward 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).
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.
CAUTION
Learn to START, STOP, and MANEUVER
the mower in a large, open area.
If the operator has not operated a ma-
chine with LEVER STEERING OR DUAL
HYDROSTATIC TRANSMISSIONS, steer-
ing and ground operation should be
learned and practiced until the operator is
completely comfortable handling the ma-
chine BEFORE ATTEMPTING TO MOW.
DANGER
Keep feet on footrests at all times when
the machine is moving. Never operate the
tractor without a deck or implement in-
stalled.
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.
