4.If the distance is less than 1”, adjust belt tension:
Move the blade lever to the “OFF” position.
Loosen the hardware (A, Figure 37) that secures the clamp that anchors the front frame assembly
(B)to the rear main case.
Pull the front frame forward until the belt spacing, with the blade lever “ON”, measures 
Retighten the hardware that secures the clamp. Make sure the hardware is tightened securely.
IMPORTANT: The SNAPPER Rear Engine Rider Models with 33” decks do not require belt tension adjustment.

5.When belt adjustment is complete, it will be necessary to check Clutch/Brake Cable slack. Disengage the park- ing brake and allow the pedal (A, Figure 38) to remain in the engaged wheel drive (Up) position. The clutch/brake cable should have approximately 3/16” of slack. If the cable does not have slack adjustment of cable must be performed:
Peel back the rubber clutch/brake pedal pad and push one ferrule (B) through the hole (C) in the pedal to attain slack in the cable.
Recheck the cable for the approximate 3/16” of slack. Replace the pedal pad when adjustment is complete.
IMPORTANT: Too much slack may cause improper clutching, and braking could be affected. Too little slack may cause improper clutch function. Recheck the service brake/park brake and readjust if necessary. Refer to the section entitled
“SERVICE BRAKE/PARK BRAKE ADJUSTMENT”.
