Two Clutch System (Fig. 4)
Power is transferred from the engine to the transaxle by
a variable clutch system that consists of two clutches
connected by a drive belt. The drive clutch responds to
engine speed, and is mounted to the engine drive shaft.
The driven clutch responds to changes in load to the rear
axle, and is mounted to the transaxle input shaft.

Both clutches work together as a matched unit. The
units automatically up–shift and back–shift with
changes in load and speed. This shifting changes the
turning ratio between the drive and driven clutches and
allows the engine to operate at optimum efficiency.
