4. If the distance is less than 1", adjust belt tension.
5. Move blade lever to the "OFF" position.
6. Loosen hardware that secures the clamp that
anchors the front frame assembly to the rear main
case. See Figure 4.6.
7. Pull front frame forward until belt spacing, with
blade lever "ON", measures 1-1/4".
8. Retighten hardware that secures clamp. Make sure
hardware is tightened securely.
IMPORTANT: The SNAPPER Rear Engine Rider Models
with 33" decks do not require belt tension adjustment. But, if
front frame assembly clamp is loosened for any reason,
recheck belt spacing between idler pulley and belt. With
blade lever in the "ON" position, the distance should
measure 1-3/4".
9. When belt adjustment is complete it will be
necessary to check Clutch/Brake Cable slack.
10. Disengage parking brake and allow pedal to remain
in the engaged wheel drive (Up) position. See Figure
4.7.
11. Clutch/Brake Cable should have approximately
3/16" of slack. If the cable does not have slack
adjustment of cable must be performed.

12. Peel back the rubber clutch/brake pedal pad and
push one ferrule through hole in pedal to attain slack
in cable. See Figure 4.7. Recheck cable for the
approximate 3/16" of slack. Replace pedal pad when

clutching and braking could be affected. Too little slack
may cause improper clutch function. Recheck service
