DECKLEVELINGADJUSTMENT
If an uneven cut is obtained, the deck may be leveled
by following instructions in Assembly section.
CUTTING DECKENGAGEMENTADJUSTMENT
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.
