5. Hold the flanged nyloc nut (on the inside
of the engine mounting plate) stationary
while turning the belt tensioning bolt
clockwise to increase belt tension.
NOTE:
As the end of the bolt extends against
the mower frame, the engine mount plate is
forced back, increasing belt tension.
•
Adjust belt to 30-35 lbs tension. This
equates to belt deflection of
approximately 0.5 inches measured at
the center of the longest belt span (RH
side of machine as viewed from
operator position). See Figure 19.
6. Turn bolt counterclockwise to decrease
belt tension.
NOTE:
Check belt deflection with
approximately 3 lbs of force (average finger
force).
7. Tighten engine mounting hardware to
14
lbf-ft (19 N•m).
8. Release PTO clutch control lever.
9. Install lower belt drive guard. See
10. Test PTO clutch. The blade must stop
within 3 seconds after releasing control
lever. If blade continues to run, adjust or
repair control components immediately.

BELT REPLACEMENT
Wheel Drive Lower Belt Replacement
1. Remove upper and lower drive belt
guards. See
NOTE:
The adjustment bracket bolt holes are
threaded.
2. Loosen the lock nut and bolt attaching
each adjustment plate to the adjustment
bracket. Do not remove hardware.
3. Loosen the flanged nut on each
adjustment hex bolt away from the
adjustment bracket.
4. Turn both adjustment bolts out evenly
until belt becomes loose enough to slide
off blade shaft pulley.
CAUTION:
If wheel drive lower belt is
installed incorrectly, the variable speed (VS)
pulley will rotate in reverse. The drive rollers
shaft will then also be driven in reverse. If
driven in reverse, the drive rollers will slip and
produce a clicking noise.
5. Twist belt 90º so left side goes to lower
side of VS pulley. Also see Figure 19.
