DECKLEVELINGADJUSTMENT

If an uneven cut is obtained, the deck may be leveled

by following instructions in Assembly section.

CUTTING DECK ENGAGEMENTADJUSTMENT

The cutting deck engagement may be adjusted to make certain deck is disengaged when lift lever is in the BLADES OFF position. Correct adjustment as follows.

With the engine off, place the lift lever in the highest cutting position (first position). Remove the cotter pin and flat washer which secure the disengagement rod to the stabilizer shaft assembly. See figure 12. Shorten the rod by threading it in until the ferrule is against the back of the slot in the lift shaft assembly, and the rod lines up with the hole in the stabilizer shaft. For more belt tension the disengagement rod must be length- ened. To decrease belt tension the disengagement rod must be shortened.

Check the adjustment by placing the lift lever in the BLADES OFF position. The deck should move up and forward, allowing the belt to become loose. Start and

test for disengagement. Repeat procedure as necessary.
