Allis-Chalmers 400 Series - Page 18

Operating Controls
the shuttle drive control lever forward from the
neutral notch causes tractor to move forward.
Moving lever from forward position rearward to
the neutral notch slows and stops the tractor. In
similar manner pulling lever to rear causes tractor
to move in reverse and pushing it forward again
to neutral slows and stops tractor.
NOTE: All continuous operation should be done
with the control lever fully forward and locked in
the forward notch, or fully to the rear for reverse.
Other than when starting or stopping or changing
from forward to reverse or from reverse to forward
the shuttle control should be in the fully engaged
position. To operate it for more than a short time
midway between neutral and fully engaged position
will cause heating and excessive wear on clutches.
Lever should be moved smoothly and steadily
forward or rearward at a slow enough speed to
prevent sudden starts or stops.
