Power is transferred from the engine to the transaxle by
a variable clutch system that consists of two (2) clutches
connected by a drive belt. The primary clutch responds
to engine speed, and is mounted to the engine crank-
shaft. The secondary clutch responds to changes in
load to the rear axle, and is mounted to the transaxle in-
put shaft.
The two clutches work together to automatically up−shift
and back−shift as changes in load and speed occur. This
shifting changes the turning ratio between the primary
and secondary clutches and allows the engine to oper-
ate at optimum efficiency.
