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.

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.

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.
