The cutting unit's belt, on the top of attach-
ment cover, is a V-belt. The blades are not
timed, they are mutual "collision proof". Con-
sequently they do not have shear pins. A
heavy-duty spring with a tension wheel gives
the belt the correct belt tension.
The angle gear input shaft is connected to
the propeller shaft using a quick coupling.
The quick coupling is released when you pull
the spring-loaded ring backwards and at the
same time the propeller shaft's sliding joint is
pressed together.
WARNING!
Never leave the rear part of the pro-
peller shaft engaged when the front
one has been released. Somebody
could start the engine.
The angle gear is a separately lubricated
gear drive with two mitre gears. The oil level
is checked with a sight glass.
The belt is driven from a pulley on the under-
side of the angle gear, which in turn is driven
by the propeller shaft.
The three blades on fitted on individual verti-
cal axles, which are bearing mounted using
large bearings in bearing housings that are
bolted to the cover.
