To decrease the gap between the friction disc
and the aluminum drive plate:
1. Loosen the upper cable nut on the wheel
drive control cable, and then tighten the
lower cable nut against the adjuster
bracket. See Figure 18.
2. Check the adjustment and readjust as
needed.
NOTE: If the gap between the friction disc
and aluminum drive plate cannot be adjusted
to this tolerance, take the unit to an
authorized service dealer for repairs.
SPEED CONTROL BELL CRANK
(self-propelled models)
The speed control bell crank holds the speed
control rod in position after a speed has been
set. The spring washers may become loose
with normal wear. If the speed control rod
does not stay firmly in position, adjust the
speed control bell crank. See Figure 19.
To adjust:
1. Remove cover, fully compress the
helical spring lock washers with lock
nut and then back lock nut off, one
quarter turn.
2. If the speed control rod is still too
loose, tighten lock nut by small
increments until it holds its position.
Tightening the lock nut too much will
not allow the speed control rod to
move at all.
3. Align notch in left hand side of cover
with bolt and secure with knob.
