Two Clutch System (Fig. 3)
Power is transferred from the engine to the transaxle
and spray pump by a variable clutch system that con-
sists of two clutches connected by a drive belt. The drive
clutch responds to engine speed, and is mounted to the
engine driveshaft. The driven clutch responds to
changes in load from the transaxle and spray pump, and
is mounted to the gearbox 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.
