Motion Control Linkage Adjustment
This adjustment must be made with the rear
wheels rotating. Raise the rear of the machine
and block it up so the wheels are free to rotate.
CAUTION: Keep hands, feet and clothing
away from rotating tires.
Tilt seat forward and remove the seat rod so the
seat may rotate forward onto the frame.
Place a 2x4 board between the foot plate and
the center of the seat to engage the seat safety
switch.
Loosen the nuts directly behind each ball joint
on both rods that connect the pump arm to the
motion control assemblies. FIG - 7

gaged and the motion control levers in the
neutral slots to start the engine. Run the engine
approximately half throttle
Release park brake to allow the wheels to
rotate.
SETUP AND ADJUSTMENTS
1. Stop engine and remove key. Release park
brake and measure the length of the spring. The
distance between the washer on each end of
the spring should be 2-7/8". FIG - 5
2. If adjustment is needed, loosen the nut below
the spring. Then rotate nut to desired position so
the proper distance between the washers is
obtained. Check other side for proper adjust-
ment.
3. Engage the brake lever and measure the
distance between the trunnion pin and the collar
welded to the brake rod. Distance should be 3/
16" to 1/4". FIG - 5
4. If adjustment is needed, loosen the lock nut
directly below the yoke. Using a wrench, rotate
the rod by turning the double nuts using the nuts
below the yoke and the nut you just loosened, to
obtain the 3/16" to 1/4" distance. Tighten nut
against yoke and check other side for proper
adjustment.
