INTRODUCTION
Congratulations on your purchase of a new Meyer Rear
Unload Forage Box. Undoubtedly you have given much
consideration to your purchase and we’re proud that you
have selected Meyer. Pride in craftsmanship, engineer
ing and customer service have made Meyer products the
finest in the farm equipment industry today.
The Model 8100 is available as a truck mounted unit or
mounted to a wagon runninggear pulled and powered by
a farm tractor. When the PTO is referred to, it means
power takeoff from the truck or from the tractor, which
ever applies. If you have a wagon model, the PTO drive
is by a rotating drive shaft connecting the tractor PTO to
the forage box drive line. This is referred to as the PTO
drive shaft. The PTO drive shaft is connected to the trac
tor for unloading, and disconnected and placed in a stor
age bracket when traveling and filling the forage box.
The Model 8100 may be referred to as rear unload box,
forage box, box or rearunload forage box in this manual.

PRE-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 any
one else from accidentally applying power to the box un
expectedly. On tractor pulled units, the connection
between the tractor PTO and box is by a removable PTO
drive shaft. For tractors, disengage the PTO drive, turn
off the engine, set the brakes and disconnect the PTO
drive shaft from the tractor.

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

References in this manual are made to a PTO drive shaft
and are applicable to tractor pulled MODELS.
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. Minimize the unloading angle on
the PTO drive shaft
to prevent wearing of universal
joints when connected to the unloading tractor
PTO. Shift the unloading tractor to “Neutral” or
“Park”. Set the brakes and turn power off. Remove
the PTO drive shaft
from the forage box PTO stor
age bracket and connect it to the tractor PTO. Be
sure the PTO yoke is securely locked to the tractor
PTO.
WITH EXTREME FORCE. KEEP ALL PERSONS
WELL CLEAR OF THE FORAGE BOX AND UN
LOADING AREA. FAILURE TO HEED MAY RESULT
IN SERIOUS PERSONAL INJURY OR DEATH.
From the operator’s seat, restart, and SLOWLY
the PTO to start the apron chains and to open the rear
door. Once the door opens, regulate the discharge flow
with the engine speed. Do not operate above rated en
gine PTO speed.
-
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 conve
nient observation.
WARNING: DO NOT STEP OVER THE PTO
DRIVE SHAFT. STAY WELL CLEAR OF THE PTO AT
ALL TIMES. FAILURE TO HEED MAY RESULT IN

HEED MAY RESULT IN SERIOUS PERSONAL INJURY
OR DEATH.
DANGER: NEVER ENTER THE FORAGE BOX
FOR ANY REASON WITHOUT FIRST SHUTTING OFF
AND LOCKING OUT POWER. FAILURE TO HEED
MAY RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
The unloading process described is to be performed by
the operator alone. This will eliminate unexpected
“start-ups” and minimize other hazards that could result
by more than one person in control. If the forage box
should become clogged, shut off all power to the forage
box and wait for all motion to stop. Shut off and lockout
power. Then clean out the machine.
When finished unloading reduce engine speed to idle
and disengage the PTO drive. Pull the rear unload box
straight ahead to pull the door away from the unloaded
pile of forage. When free, gravity will allow the door to
swing shut and the door latches will engage the apron
chain links to secure it shut. Observe that this happens
properly.
Tractor Pulled:
Set the brakes and turn the tractor “OFF”. When all
movement has stopped, disconnect the PTO drive shaft
from the tractor and return it to its storage bracket. Secure it with the rubber tie down strap.
WARNING: DISCONNECT PTO DRIVE SHAFT
BEFORE CLEANING, ADJUSTING, LUBRICATING
OR SERVICING THIS MACHINE. FAILURE TO HEED
MAY RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
Never enter the forage box for any reason if there is any
possibility of power being applied to the unit.
Allow box to completely clean out the last load of forage.
It is recommended to lube the rear unload box before
storage to exclude moisture from bearings. Apply oil to
roller chain drives with gravity oil luber and to the apron
chains with a brush. This is also a good time to inspect all
adjustments and check for parts that need repair or re
placement. Performing these tasks now will guarantee
that the box is ready for use at the beginning of the next
season.
Never use “live” power to aid in the clean-out of a
clogged machine. If any mechanism fails, move the for
age box to a safe work area and then repair the mecha
nism before proceeding with unloading of the forage. If
repairs require removal of forage from inside the forage
box, remove the rear discharge door (bolted hinges on
top of each side) and empty the forage manually by hand
through the rear opening.

Correct tension on the apron chains is when the
apron chain slat is 1/8” to 1/4” off the return slides (three
feet from the front of the box). To tighten chains, tighten
the adjuster bolts at each end of the front sprocket
shafts. Each apron chain has its own sprocket shaft.
Tighten the adjuster bolts at each end of the shaft
equally.
The roller chain drives are tensioned by automatic spring
loaded tension blocks. Periodically eye bolts will need to
be adjusted to maintain proper spring tension. Springs
should be stretched to obtain approximately 1/16” gap
between windings.

GATE DELAY PACKAGE (#8100 - GATE) (PRIOR TO SN 0781253)
GATE DELAY INSTRUCTIONS & ADJUSTMENTS
The purpose of the gate delay system is to hold the rear swinging gate in the open position until the apron has cleaned
all of the forageout of the box. By adjusting the flow controlthe speed in which the gatecloses can be regulated. When
the flow control is properly adjusted the gate will slowly close as the remainder of the forage is being unloaded. Once
the box is completely unloaded the gate delay will reach a trip position with the trip arm moving the lower cylinder shaft
out of the horizontal slot and allow the gate to trip closed and latch. For proper operation adjust as follows. When the
gate is completely closed (tight to rear upright) the cable and eyebolt assembly should be adjusted so the cable has no
slack. Cable should be tight but not over tightened. If cable and eyebolt is over tightened the lower cylinder will trip out
of the L-shaped slot on the lower bracket prematurely and the gate will try to close before the cylinder is fully extended.
If the cable and eyebolt is too loose the lower cylinder will not trip out of the L-shaped slot and the cylinder will reach its
maximum stroke and the trip arm will still not be in the tripped position allowing the gate to close. The gate will be held
open by the top cylinder bracket and the bracket may become damaged over time. The eyebolt and cable will need to
be adjusted periodically to maintain proper operation.
