Walker R21 User Manual

R21 Operating Instructions
21
The Forward Speed Control (FSC) lever sets the
maximum forward speed, and also sets the for-
ward position of the steering levers.
The steering levers operate only with a back-
ward pulling movement of the lever, which
causes the drive wheel for that lever to rst slow
down, stop, and then reverse with a full backward
lever stroke. The levers are released to the FOR-
WARD position for “straight-ahead” ground travel.
NOTE: Pushing forward on the steering levers will
not cause any change in tractor motion - there will
be no steering lever reaction and there will be no
machine damage.
