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 Drive

Belt Guards on page 18.

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.

See PTO CLUTCH CABLE

ADJUSTMENT on page 17.

BELT REPLACEMENT

Wheel Drive Lower Belt Replacement

See Figure 21.

1. Remove upper and lower drive belt

guards. See Drive Belt Guards on

page 18.

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.
