CLuTCH
This clutch system provides a high pulley ratio (a low gear-
so to speak) to start out and a low pulley ratio ( a high
gear- so to speak) for a high speed operation, with infinite
variation between the two.
This means that it will not be necessary to give full throttle
in order to "break the blades/pans loose". The machine can
slowly be brought up to speed.
The torque sensitive pulley (Figure 26) utilizes a spring and
cam bracket. Peak performance results from proper
interaction between the driven pulley spring and the ramp
angle of the cam bracket.

NOTICE
If replacement of the clutch is required, use clutch replacement kit, P/N 22581, to upgrade to Multi-Clutch system. New
style drive assembly must be installed per instruction sheet, P/N 23444, included with clutch replacement kit.
Old style Comet clutch is no longer available. Multi-Clutch components are not interchangeable with the prior Hoffco
Comet drive system. The Hoffco Comet CVT system must be replaced for combatibility with the new equipment.
