centering bolt as required.
7. Move the directional pedal into the “reverse”
position and release it. The rear wheel
should stop rotating as soon as the pedal is
released. Stop the engine and adjust the
centering bolt as required.

9. Raise the rear of the machine, remove the
jack stands, and lower the machine.
10. Adjust the position of the directional pedal
ball joints so the pedal hits the floor when
the directional pedal is pressed backward.
The backward travel should be restricted so
the machine will not travel faster than 3 mph
(5 km/h) in reverse.
11. Tighten the directional pedal ball joints and
jam nuts.
LIFT ARM SPEED LIMITER
The lift arm speed limiter limits the forward speed
the machine can travel when the hopper is raised.
The speed limiter should be adjusted whenever
the pump control linkage is adjusted. The
machine should travel 2 mph (3 km/h) with the
hopper raised.
The speed limiter consists of a cam under the
directional pedal with a link to the lift arms. When
the hopper is raised, the link lifts the cam under
the pedal. This limits how far the directional pedal
can be pressed, limiting the machine speed.
To adjust the limited speed, raise the hopper and
engage the hopper support bar. Loosen the two
bracket bolts and slide the bracket and cam
forward to increase speed or slide the bracket
backward to decrease speed. Tighten the bolts.
