BEFORE OPERATION
Check entire unit carefully before first operation. Tighten bolts, set screws, and chains which might have
come loose in handling. Lubricate as explained in the lubrication guide. Run entire feeding mechanism
and unloading mechanism for several minutes. This will serve as a break-in and as a check that all parts
are assembled and lubricated properly. Successful operation will be achieved by periodic adjustments and
experience of the operator. Make sure to read and understand the main feeder apron adjustments.
Hitch To PTO Length – Tractor Drive Only
Maintain correct distance between tractor drawbar hitch and tractor PTO and tractor drawbar hitch and the
universal joint at front of unit. This is necessary to prevent overextending the universal joint shaft.
-12-
IMPORTANT! DO NOT operate unless 2’’ minimum extension is maintained.
The tractor drawbar should be adjusted in relation to the tractor PTO shaft as follows:
1. Hitch point of drawbar 14 inches behind tractor PTO shaft.
2. Hitch point of drawbar at least 8 inches, but not more than 14 inches below PTO shaft.
3. Hitch point of drawbar at least 13 inches, but not more than 22 inches above ground level.
4. When unloading, keep hitch point of drawbar - PTO shaft - in a straight line to forage box - having
PTO at an angle will result in a pounding noise and damage to U joints and the safety clutch.
The Power Take Off Shaft from tractor to box should not be connected
for road travel or field operation. Damage may result to the PTO Shaft.
A convenient hanger is provided to hold PTO Shaft during the time it is
not being used to unload. (See item A)
