REAR UNLOAD OPERATION
Whenever adjusting, cleaning, lubricating or otherwise
servicing this forage box, you must shutoff and lockout
power to the box. Because this box can be truck
mounted or powered by a tractor, methods vary. On
truck mounted units, the connection between the PTO
and box is permanently installed and not intended to
be disconnected. On trucks, disengage the PTO drive,
turn off the engine, set the parking brake, remove the
ignition keys and keep them in your possession to
prevent anyone else from accidentally applying power
to the box unexpectedly. For tractors, disengage the
hydraulics, turn off the engine and set the brakes.
Throughout this manual, when directed to shutoff and
lockout power, be familiar with the previously
described procedures for the type of machine you are
operating.
WARNING: MAKE CERTAIN EVERYONE IS
WELL CLEAR OF EQUIPMENT BEFORE
APPLYING POWER. FAILURE TO HEED MAY
RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
Tractor Pulled:
Always park the forage box and unloading tractor in a
straight line. Shift the unloading tractor to “Neutral” or
“Park”. Set the brakes and turn power off.
Make sure all persons are clear of the forage box and
the unloading area.
The rear discharge door opens automatically by
releasing its latches as the main aprons begin to
move. The rear discharge door can spring open with
extreme force when its latches release. See figure 1.
Pressure of forage against the rear door causes it to
spring open very quickly.
WARNING: THE REAR DISCHARGE DOOR
CAN SPRING OPEN QUICKLY AND WITH
EXTREME FORCE. KEEP ALL PERSONS WELL
CLEAR OF THE FORAGE BOX AND UNLOADING
AREA. FAILURE TO HEED MAY RESULT IN
SERIOUS PERSONAL INJURY OR DEATH.
From the operator’s seat, restart, and SLOWLY
engage the apron chains to open the rear door. Once
the door opens, regulate the discharge flow with the
engine speed. Do not operate above rated engine
speed.
Double Door Option:
During unloading, load pressure and chain movement
will force the doors to open. Oil will be forced out of
the cylinder and into the hydraulic return line. After the
box is unloaded, reverse the control lever in the
tractor and the return line will become pressurized and
force oil back into the cylinder to close the doors. A
check valve in the system will keep the box from
running backwards. This check valve should be set at
1/4 turn open. NOTE: Never force the doors open
when the line is pressurized. To open the doors with
the box empty, Shut the Tractor OFF
and move the
control lever into the unloading position and pull the
doors open slowly. Another option would be to remove
the return hose from the tractor, release pressure in
the system, remove the hydraulic tip from the hose
and let the oil drain into a container while opening the
doors. Approximately 1-cup will come out from the
cylinder travel.
Unloading is best observed from the operator’s seat.
Keep moving the forage box forward to prevent silage
from being carried underneath into the main apron
chain return area.
The front of the box has a plexiglass window for
convenient observation.
