Chapter 2 — Belts, Controls and Linkages
INTRODUCTION
All models use two belts. One to drive the auger and a
second to drive the traction system. The auger drive
uses a combination idler and brake to engage the belt
for driving and to disengage the belt and apply the
brake for stopping.
The traction drive uses a constantly tensioned belt. The
clutching and shifting are done through the drive plate
and friction disc.

Pull the wire off of the spark plug and ensure the
wire does not contact the spark plug.
5.
Slip the auger belt off the pulleys. Note: On some
models (typically the 824 and the 824XL) the
auger belt brake will not back off far enough to
remove the belt. Remove the front screws and
loosen the rear screw that fastens the brake arm
assembly to the chassis (Figure 37).
3.
Remove the two screws that hold the belt cover in
place and set the cover aside (Figure 35).
