Centrifugal clutch
The centrifugal clutch has the task of transferring
the power from the engine to the cutting equip-
ment’s drive axle. As the name implies, it works
according to a centrifugal principle.
This means the clutch’s friction shoes are thrown
outwards towards the clutch drum at a certain
engine speed. When the friction against the drum
is sufficiently great it drives the drive shaft at the
same speed as the engine.
Some slipping occurs between the clutch and
the clutch drum when accelerating as well as
in the reversed situation when the cutting
equipment jams. Thereby preventing abnormal
load changes on the crankshaft.
The engagement speed has been carefully
tested so that the engine can idle without the
cutting equipment’s drive shaft rotating.

tained.
