INTRODUCTION
Congratulations on your purchase of a new Meyer Rear
Meyer Manufacturing Corporation reserves the right to
make improvements in design, or changes in specifica-
tions at any time, without incurring any obligation to own-
ers of units previously sold.
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.
This supersedes all previous published instructions.
The Model 8100 is available as a truck mounted unit or
mounted to a wagon running gear 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.
IMPORTANT:
At the front of this manual is a Product Registration and
Inspection Certificate. Be sure your dealer has com-
pleted this certificate and promptly forwarded a copy to
Meyer Manufacturing to validate the manufacturer’s
warranty. The product model and serial number are re-
corded on this certificate and below for proper identifica-
tion of your Meyer Forage Box by your dealer and the
manufacturer when ordering repair parts. The serial
number is stamped in the front upright of the left-hand
side.
The Model 8100 may be referred to as rear unload box,
forage box, box or rear unload forage box in this manual.
This SAFETY ALERT SYMBOL means ATTEN-
TION! BE CAREFUL! YOUR SAFETY IS INVOLVED! It
stresses an attitude of HEADS UP FOR SAFETY. When
you see this symbol, be alert to the possibility of PER-
SONAL INJURY and carefully read the message that fol-
lows.

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.
DANGER: DO NOT OPERATE WITHOUT PTO
GUARD ON MACHINE AND ON TRACTOR OR TRUCK.
FAILURE TO HEED MAY RESULT IN SERIOUS PER-
SONAL INJURY OR DEATH.
DANGER: MAINTAIN PTO DRIVE SHAFT
GUARDS IN OPERATING CONDITION. REPLACE
THEM IF DAMAGED AND NOT TURNING FREELY.
FAILURE TO HEED MAY RESULT IN SERIOUS PER-
SONAL INJURY OR DEATH.
WARNING: INSPECT REGULARLY THAT ALL
CONNECTIONS AND BOLTS ARE TIGHT AND SE-
CURE BEFORE OPERATING. FAILURE TO HEED MAY
RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
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.
References in this manual are made to the PTO drive
shaft and are applicable to tractor pulled MODELS.
Inspect the forage box for proper adjustments as this will
ensure maximum machine performance. See “Adjust-
ments” section. Grease and oil the forage box as re-
quired. See “Lubrication” section.
Be sure your forage box is properly mounted to the truck
frame or to the wagon running gear. Consult your dealer
if you have any questions about proper installation. A tie
down kit from the manufacturer and illustrated in the
parts listing of this manual is available for wagon applica-
tions.
WARNING: DO NOT OPERATE UNTIL ALL
SHIELDS AND GUARDS ARE IN PLACE AND SE-
CURELY FASTENED. FAILURE TO HEED MAY RE-
SULT IN SERIOUS PERSONAL INJURY OR DEATH.
Input speed to the forage box line shaft must be 540 rpm
maximum. On trucks the PTO drive must be reduced to
obtain this speed. For tractors, select the 540 rpm option
according to manufacturers instructions.
For tractor pull model, set your tractor drawbar to con-
form to the standard dimensions shown on the following
illustration. This will ensure that the PTO drive shaft will
not be over extended.
Before filling the box, slowly engage the PTO and oper-
ate box at idle speed to ensure it is operating properly.

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.
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.
The front of the box has a plexiglass window for conve-
nient observation.

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.
HINGE BOLTS
Make sure all persons are well 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.

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.
WARNING: DO NOT STEP UP ON ANY PART
OF THE FORAGE BOX AT ANY TIME. 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.
Never enter the forage box for any reason if there is any
possibility of power being applied to the unit.
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. Se-
cure 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.
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 forage out of the box. By adjusting the flow control the speed in which the gate closes 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.
