DECK LEVELING ADJUSTMENT
If an uneven cut is obtained, the deck may be
leveled by following instructions in the Assembly
section.
CUTTING DECK ENGAGEMENT
ADJUSTMENT
The cutting deck engagement may be adjusted to
make certain deck is disengaged when lift lever is in
the BLADES STOP 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 18. 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 disengagement rod must
be shortened.
Check the adjustment by placing the lift lever in the
BLADES STOP position. The deck should move up
and forward, allowing the belt to become loose.
Start and test for disengagement. Repeat procedure
as necessary.

BRAKE ADJUSTMENT (See Figure 19)
The brake is located by the right rear wheel inside
the frame. The brake has been set at the factory to
the proper clearance. 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
running 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.
