PREPARING FOR OPERATION
Check over entire unit carefully before first operation. Tighten bolts, set screws, and chains which
may have come loose in handing. Lubricate as explained in the Lubrication Guide. Successful operation
will
be achieved by periodic adjustments and experience of the operator. Make sure to read and
understand all adjustments.

ttach the Forage Box PTO to the tractor PTO shaft locking it into position. Maintain correct distance
between
the
tractor drawbar hitch, tractor PTO and the universal joint at front of unit. This is necessary
to
prevent overextending the universal joint shaft.
IMPORANT! DO NOT operate unless 2” minimum extension is maintained.
After the correct distance is obtained, depress the locking collar
against the spring tension, and slide
the
yoke onto
the
tractor PTO shaft. Release the locking collar and move the yoke ahead or back until the
lock engages into the groove on the shaft.
NOTE:
Do NOT attempt to use a hammer to help in attaching the PTO drive connection.
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 sh
aft.
2.
Hitch point of drawbar at least 8 inches, but not more than 14 inches below PTO sh
aft.
3.
Hitch point of drawbar at least 13 inches, but not more than 22 inches above ground le
vel.
4.
When unloading, keep
the
hitch point of
the
drawbar
and
PTO shaft in a straight line to the Forage Box
.
If the
PTO
is
at an angle
, it
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.
The telescoping PTO drive is designed to rotate freely inside the drive shield tubes.
Run the unloading
mechanism for several minutes. This will serve as a break-in and as a check that all parts are
assembled and lubricated properly.
After you have run the Forage Box for several minutes, check the main apron chains again for proper
adjustment, as paint may initially come off the apron chains and chains may loosen. The main apron
chains must be taken up evenly before you use the forage box. Check again after the first few loads.
The
main aprons should be at proper tension at all times. See Adjustment Section for details.

nt
ain a straight alignment between the Forage Box
and the tractor.
2.
Maintain a distance of 6”- 12” between the top of the tractor drawbar and the center of the tract
or
PTO.
An 8” distance is standard.
