BRAKE ADJUSTMENT (See figure 15)
The brake is located by the right rear wheel inside the
frame, During normal operation of this machine, the
brakes are subject to wear and will require periodic
examination and adjustment.
WARNING: Do not have the engine run-
ning when you adjust the brake.
To adjust the brake, adjust the nut so the brake starts
to engage when the brake lever is 1/4" to 5/16" away
from the axle housing.
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 disengaged position, or to obtain more drive in the
cutting positions. 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 14.
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 lengthened. To decrease belt tension the dis-
engagement rod must be shortened.
Check the adjustment by placing the lift lever in the
disengaged position. The deck should move up and
forward, allowing the belt to become loose. Start and
test for disengagement. Repeat procedure as neces-
sary.
