BEATER ENGAGE, APRON SPEED

This single lever (A) controls both beater engage/
disengage and the speed of the main feeder aprons.
CAUTION:
DO NOT ENGAGE BEATERS OR MAIN
APRONS WHEN CROSS CONVEYOR IS FULL
OF MATERIAL OR DAMAGE TO FORAGE BOX
WILL RESULT. Prior to engaging beaters and main
aprons, intermittently rotate emergency stop lever
(B) to the engage position to clear cross conveyor of
all material. When beater control lever is engaged,
the beaters will start. Rotating lever downward starts
and gradually increases main apron speed. AFTER

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

drive belt, follow the steps listed below to remove
worn belt:
1. Place control lever in beater disengage position.
2. Open upper sheaves (A) so belt rests on drive
pins.
