BEATER CLUTCH ADJUSTMENT
Check beater clutch periodically to insure beaters
are being completely engaged or disengaged. Beater
engage/disengage clutch is properly adjusted when
there is 1/8 inch of clearance between clutch jaw (A)
and engaging pin (B), when control lever is in the
disengage position. Basic adjustment can be made
by positioning adjusting nut (C) 2-7/8’’ from end of
control rod. Place control arm (D) tight against nut.
Adjust mounting bracket (E) in slotted holes on unit
until 1/8’’ clearance is reached. Fine adjustment is
made by adjusting nut (C) on control rod.

After extended use of forage box, it may become nec-
essary to adjust or replace variable speed drive belt.
