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.
TRACTION CONNECTIONS
PTO Drive
-14-
Attach 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 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 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.
1. Maintain 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 tractor PTO.
An 8” distance is standard.
(Shields are
removed
for viewing)

OPERATION
Check entire Forage Box carefully before first operation. Tighten bolts and set screws that might have
come loose in transporting. Lubricate if needed as explained in the Lubrication Chapter in this manual.
EMERGENCY SHUTDOWN
In case of an emergency, pushing the emergency stop
panel, emergency stop bar, or pulling the safety cable will
stop cross conveyor, beaters, and main aprons. PTO will
continue to rotate. If the Forage Box is plugged with material
or a foreign object becomes lodged in the discharge area,
disengage the PTO. Stop the tractor engine, remove ignition
key, and allow all mechanisms to stop before cleaning or
working on the machine. Trip emergency stop occasionally
to insure proper function.
GENERAL INFORMATION

CONTROLS & SAFETY EQUIPMENT
Forage Boxes are provided with several features for operator safety and convenience.
Guards & Shields
Whenever possible and without affecting the operation of the Forage Box guards, shields and/or hinged
shields have been used on this equipment to protect potentially hazardous areas. In many places,
decals are also provided to warn of potential dangers as well as to display special operational procedures.
A spring loaded plastic guard which
protects the operator from accidentally being
exposed to the beater and apron at the
discharge opening during operation of the
Forage Box. Keep this guard in proper
position at all times when operating the
forage box.
PTO Shields
Care must be taken to keep male and female driving elements well lubricated and free sliding. The shield
surface must be kept dry, as dirt accumulation on them will quickly cause these units to bind and not
rotate. If, at any time the shields do not turn freely, they should be checked to determine the cause, and
repaired or cleared. DO NOT STEP OVER PTO SHAFT. STAY CLEAR OF ROTATING PTO AT ALL
TIMES. DO NOT OVEREXTEND PTO.

OPERATION
OPERATION OF FRONT UNLOAD FORAGE BOX
1. Park the Forage Box on level ground whenever possible during unloading. Lock tractor parking brake
2. Connect the PTO to a tractor with a 540 PTO ONLY, locking securely in place as stated in the
PREPARING FOR OPERATION SECTION.
3. Engage PTO
4. To engage cross conveyor
INTERMITTENTLY, rotate clutch
lever (A) clockwise and hold with hand
pressure. If hand pressure is
removed, the cross conveyor will
stop.
5. To engage the cross conveyor
CONTINUOUSLY, rotate clutch lever
clockwise until it locks in the engage
position. Cross conveyor speed is
controlled by the tractor RPM only.
6. Quickly engaging/disengage beater lever will allow beaters to clear material a little at a time to avoid
exceeding blower capacity. This single lever 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.
7. When beaters are clear of material, move control lever to apron speed position. Variable speed
drive offers you a number of unloading speeds to choose from. Rotating the lever downward
starts and gradually increases main apron speed. With experience and depending on the type of forage,
you will be able to select a speed which will match your blower capacity. Unloading speed may also
be varied by increasing or decreasing engine speed of tractor.
8. If it is necessary to trip the stop mechanism and disengage the Forage Box drive before the box
empty, restart unloading by engaging clutch lever.
9. Clean out position is for cleaning out the forage box at the end of the load.
10. When the Forage Box is empty, move the control lever to disengage position. AFTER
UNLOADING, ALWAYS RETURN THE CONTROL LEVER TO THE NEUTRAL POSITION WITH PTO
RUNNING.
11. Disconnect the PTO and place it in the convenient holder for field and road use.
NOTE: Do NOT exceed the rated 540
RPM operating speed of the Forage
Box
