BASIC INFORMATION.
Application: All 300 Series models.

double reduction transmission for multiplying and
transmitting engine torque to the auger. The principle
involves engine horsepower and torque being
transmitted through a centrifugal clutch and two sets of
gear reductions into a final driveshaft. Oil is provided
for lubrication and heat dissipation for the bearings,
gears and clutch assembly.
The principal variance which exists between specific
models occurs with the driveshaft configuration
