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.
