Adjusting the Compression Spring

1. Raise the mower lift lever to the transport position.
2. Check the distance between the two large washers,
which should be 11-1/2" (29.2cm) (Fig. 836).
3. Adjust this distance, by loosening the spring jam nut
and turning the nut in front of each spring (Fig. 836).
Turning the nut clockwise will shorten the spring;
counter-clockwise will lengthen the spring.
4. Lock the nut into position by tightening the spring
jam nut (Fig. 836).
