SPEED CONTROL ADJUSTMENT
(See Figure 15)
NOTE: When operating the unit initially or after
replacing the belts, there will be little difference
between the highest two speeds until after the belts
have gone through a break-in period and have
seated themselves into the pulleys.
First, adjust the speed control lever as follows:
1. Place the shift lever in Neutral position.
2. Start the engine.

then slowly depress the pedal all the way (to
disengaged position). Hold the pedal in this
position.
5. Turn the engine off.
6. After engine stops completely, release the
clutch-brake pedal.
7. Disconnect the speed control link from the
variable speed bracket by removing the hairpin
clip and flat washer from the stud located on the

8. Depress the clutch-brake pedal forward until the
stop on the clutch-brake pedal assembly hits
solidly against the underside of the frame.
9. Remove the hairpin clip and flat washer from
the rod attached to the back of the speed
control lever.
10. Place the speed control lever in parking brake
position.
11. Thread the ferrule on the rod until the ferrule
slips into the bottom end of the slot in the speed
control lever, then thread the ferrule down on
the rod one full turn (to shorten).

second position.
b. 5-speed units: Place speed control lever in
