SAFETY FIRST
FARM AND INDUSTRIAL EQUIPMENT INSTITUTE SAFETY ALERT SYMBOL.
This symbol is used preceding all CAUTION (a general safety
reminder), WARNING (denotes a potential hazard), and DANGER
(denotes a potential injury) notices!
Most farm accidents, like industrial, home, and highway accidents are caused by the failure of some
individuals to observe simple and fundamental safety rules or precautions. For this reason, farm
accidents, just as other types of accidents, can be prevented by recognising the causes of accidents
and doing something about them before an accident occurs.
Regardless of the care used in the design and construction of farm equipment, there are many points
that cannot be completely safeguarded without interfering with accessibility and efficient operation.
A CAREFUL OPERATOR IS THE BEST INSURANCE AGAINST AN ACCIDENT
The complete observance of one simple rule would prevent many thousand serious injuries each year.
That rule is "NEVER ATTEMPT TO CLEAN, OIL, OR ADJUST A MACHINE WHILE IN
MOTION". NATIONAL SAFETY COUNCIL

USINGYOUR ROTO-PRESS
READ CAREFULLY
SETUP
1. When your receive your new ROTO-PRESS from the factory, it is not immediately
necessary to check the machine for bearing lubrication, or chain tightness as these items
have been factory serviced. It is recommended to walk around the machine and familiarize
yourself with the location of all moving parts, caution decals, the general operating
dimensions and the basic working features of the ROTO-PRESS.
CAUTION! BEFORE OPERATING THIS MACHINE, READ AND
UNDERSTAND THIS OWNER’S MANUAL AND ALL CAUTION,
WARNING AND DANGER SYMBOLS LOCATED ON THE
MACHINE AND IN THIS MANUAL.
2. All lubrication has been completed at the factory prior to delivery, and will not be
immediately necessary. The oil bath has been filled to the proper level. Take note that the
oil does not run any higher than approximately halfway up the very lowest part of the drive
chain. All bearings should be greased according to the enclosed lubrication schedule.
IMPORTANT! DO NOT OVER GREASE BEARINGS, SEAL FAILURE AND
SUBSEQUENT PREMATURE BEARING FAILURE COULD RESULT.
OPERATION
CAUTION! BEFORE ATTEMPTING TO RUN THE ROTO-PRESS
CHECK THE AUGER CHAMBER FOR FOREIGN MATERIAL. MAKE
SURE THAT ALL SHIELDS ARE IN PLACE, AND THAT ALL SAFETY
DECALS ARE UNOBSTRUCTED.
1. Pick a tractor large enough for your application; it is better to be too big than too small.
Some general horsepower requirements are: hay or cracking requires 130 hp, ground ear
corn or snaplage requires 115 hp, shell corn requires 80 hp. Fuel tank on tractor should be
full before starting. Hook up the tractor to the bagger.
2. Before you begin to set-up the ROTO-PRESS, pick a suitable location for the bag(s). The
location should be well drained, smooth, and fairly solid; long enough for the size bags you are
using and easily accessible for both filling and unloading. Check the length and remember that
the tractor and bagger take approximately 40-50 feet extra. Also, a slight incline (uphill) is
preferred, however there should not be a side hill. If there is a choice of bagging uphill or
downhill, always bag uphill. Remember that these are only recommendations, as it can be
done almost anywhere.

2
3. Position the ROTO-PRESS in a straight line with the tractor in the direction that you want to
bag, making sure that the wheels of the tractor are pointed straightforward. See Figure 1.
Keep checking the tractor front wheels while filling the bag, making sure that they are
straight at all times. Many people will grab the steering wheel when getting on/off. Try not
to do this. Remember to leave an additional 10 to 15 feet of room to put the bag on when
positioning the tractor and bagger.
Figure 1
4. In certain wet or soft conditions, the Roto-Press will try to push the tractor sideways. To
correct this, use a section of chain with binders, hook one end to the grab hooks located on
the ROTO-PRESS frame near the bottom of oil bath and attach the other end of the chain to
the tractor axle. Do this on both sides of the machine.
TRANSPORT LIGHTING
1. When you receive your ROTO-PRESS, the transport lighting should be in the open position,
meaning the lights are visible from the rear of the machine. Once the machine is positioned for
bagging, the lights must be moved into the closed position. The light assemblies are accessible
from the front of the machine, located behind the wheels. To close the light, pull the pin
holding the light assembly and pull the assembly forward until it bumps against the stop.
Replace the pin back into the additional hole in the light assembly bracket to hold the light
assembly in the closed position.
2. Before transporting the machine to a new location, reverse the process as described above.
It is very important to reposition the lights each time the machine is transported.
BAG INSTALLATION
1. Loosen the single chain loop on the bungee cord from the notched bar on the bag apron and
then disconnect the hooks on both ends. Disconnect the yellow rope with hooks from the
bagger’s front shroud. Unhook the apron chain from the apron support and lower apron to the
ground. Figure 2

3
WARNING! ALL WORK TO INSTALL THE BAG SHOULD BE
DONE FROM THE GROUND & BY STEPS ON AXLE. DO NOT
CLIMB ON THE ROTO-PRESS. CLIMBING ON UNIT MAY
RESULT IN INJURY OR DEATH.
2. a. Winch the trolley\bag lift (if so equipped), pulling it along on both sides while standing
on the ground and lower to approximately 3’ off the ground. Note: 3 or more people
should be present at this point.
b. If the ROTO-PRESS is not equipped with a bag boom, follow the instructions as
outlined, except the bag will have to be manually lifted over the tunnel.
3. Position the box containing the proper size bag for your bagger behind the bag lift. Making
sure the arrow is toward the machine. Cut the straps around the box and remove the top
portion, and discard. Unfold the bottom portion of the remaining box. Remove the (2) blue
straps that are holding the bag together. Making sure the black or inner side is toward the
machine, have one person on each side of the bag; take a flap, lift and lay the top halves out
and stretch the entire bag flat. Two (2) people should put their arms between the top flaps and
put the bag around the bag lift. Remember to position the bag so the bars and lettering used to
measure the stretch of bag are easily reached (approximately 3’ to 4’ from ground).
4. Put the bag around and under bottom of the shroud making sure that the bottom bag folds
come off first. Then winch the bag lift up and move trolley\bag lift back over the shroud. 10ft.
Units only: Remove the locking pin from the bag lift support and raise it to the UP position,
then replace the locking pins. Repositioning trolley\bag lift over the bag support, and lower
onto supports. Caution: Do not over tighten bag lift cable as to bow bag lift ends. Be
careful not to pinch the bag.
5. Using the two (2) blue straps cut earlier and the bottom of the box (to protect the bag from
sliding on the ground), lift and place around bottom position of bag, slide the cardboard so
that the flaps will just go up on to the apron. Then slide the bottom of the bag on the box
and onto the bag apron. Make sure the bag is to the inside of the apron support. Raise the
bag lift and roll it forward all the way to the front, sliding the bottom of the bag along on to
the bag apron. Slide the cardboard just off the pan and discard.
6. Cut the remaining straps and remove them, being careful not to cut the bag. Carefully pull the
inside of layer of the bag off with a gentle tugging action. Do not pull the rest of the bag off of
the bag lift. Pull the bag off to 6 feet behind the machine. With one person on each side, pull
the main part of the bag out and forward on the apron. This will get the wrinkles out and avoid
getting the bag caught between the bag apron and the machine.

7. The following must be done on both sides: raise the bag apron up and lock the chains in the
slots. Put the bungee cord over the bag just behind the main bag yet ahead of the pipe. Place
ropes with the bottom side of the bag apron and the hook onto the chain links (keeping the
hook to the outside so not to catch on the bag) holding the apron up about half way up to
begin. (Figure 2) The cord must be tight and go on the front side of the apron (Very
Important). Tie the ropes on the bungee cord forward to their appropriate hooks.
8. To close the bag, pull enough off of the shroud so that you can close off the one end. Pull a
little more off of the bottom to start out. It is important not to allow wrinkles and to keep the
bag fold lines straight. Take the opening of the bag and fold in both sides to form a pleat. Also
requires the use of (2) 10’ 2 x 4’s. (Figure 3) Place the blank board on top and roll the bag
around it four (4) times. Place the pre-nailed board on top to sandwich the plastic and nail them
together.
Figure 3
9. Let the boards hang down or prop them up by placing a bale or truck, tractor or skid loader to
act as a back stop to hold it securely for the first three loads. This is to compensate for the bag
coming off the top, later. Check that the apron is just loose enough to let off one fold at a time.
Also check for tearing at the bottom. If this occurs, loosen the bungee cord and tape the tear.
10. Read directions and information sheet in the bag box completely. Measure for proper
stretching of the bag. ROTO-PRESS does have the ability to over stretch and burst the bag.
WARNING! DO NOT STAND UNDERNEATH THE CONVEYOR WHILE
IT IS BEING LET DOWN.
11. The conveyor is raised and lowered with a hand-operated winch mounted on the side of the
oil bath. The conveyor slide mechanism is equipped with a safety lock that prevents the
conveyor from coming down accidentally. When lowering the conveyor, release the safety
lock by first raising the conveyor slightly, and then pull down on the safety lock handle.
Remember to make sure that the safety lock is engaged, each time the conveyor is returned
to the transport position. Lower down to just off the ground, or to the desired height,
making sure the conveyor never comes in contact with the ground. Flip the hopper end
chute over into its operating position. Hook up the tractor hydraulics and check the belt
rotation to make sure the belt is moving in the right direction. If available, adjust the tractor

5
hydraulic flow to as slow as possible, and then adjust the ROTO-PRESS flow control to the
desired speed. This will decrease the amount of heat created, by reducing the amount of
excess oil pushed over the bypass of the flow control.
12. The ROTO-PRESS conveyor is equipped with a safety stop bar located across the width of
the conveyor and is easily accessible from either side. Pulling the safety bar down will
instantly shut the conveyor off. Pushing it up will resume operation. Always check the
operation of the safety stop bar before beginning to fill the bag.
13. ROTO-PRESS that are equipped with auger units need to be mounted at this time using a
loader and a chain to raise the auger up. Lower the peg in the hole on the right side of the
machine. Hook up the hydraulic hoses. Place as far forward as possible.
14. To set the brakes on the ROTO-PRESS, remove the keeper pin on top of the brake assembly.
Take the brake handle\wrench and insert into the tube and then pull down. Tension is
adjusted by using brake\wrench handle on center portion of turnbuckle and turning or, older
units turning the nut located on the threaded portion of the connecting rod.
ATTENTION! DO NOT SET THE BRAKES ON THE ROTO-PRESS SO TIGHT
THAT IT CAUSES THE BAG TO SLIDE ON THE GROUND, THIS WILL TEAR
THE BAG! SET THE BRAKES ON THE BAGGER LIGHTLY FOR THE FIRST
THREE LOADS!
Adjust the ROTO-PRESS brakes as necessary after the first three loads.
15. Place the transmission in neutral, but not park! This is very important! Start the tractor
and run at PTO speed. Lock in the hydraulic lever to run the conveyor.
BAG FILLING
1. The bag fills in direct relationship to the machine filling it. Watch the bag and the folds as
they come off of the cone, as they must come off evenly. If either the top or bottom gets
ahead, then pull off whatever is necessary to straighten them out or it will only continue to
get worse. The unfolding bag must be regularly checked, because at certain conditions such
as temperature, bag apron position or improper bungee cord tension, the bag may come off
two or more folds at a time. If the bag is regularly checked, this will be no problem as the
extra fold can be retucked into place. If not regularly watched, the whole bag could come
off the end of the bagger.

2. Start filling; pull the bag toward the rear to avoid wrinkles on the ground. It may be
necessary to adjust the position of the bag pan and bungee cord after some of the bag has
come off.
3. An overflow door placed just behind the conveyor tells you if you need to slow the conveyor
down. On the front side of the conveyor is a flow control to regulate the speed of the
conveyor.
On roller mill units, adjust the slide control on the top so that the corn is getting to the entire
roller. It should be mounded up just a little to make this happen.
On auger units, do not overfill the hopper. If it is full at the tube opening, that is good
enough.
4. Continue filling the 2nd load. Check that the wheels are not sliding. Also, check the stretch
marks on the bag. Do these about five (5) feet behind the machine. Apply or release the brakes
according to the bag manufacturers allowable stretch.
On roller mill units, check the desired crack. Check this at the inspection hole on the right side
of the machine. Adjustments can be made at the rear, left hand side of the units.
5. On every load, check the stretch of the bag. Check whether it is coming off straight, check the
tractor alignment and inspect the bag for tears.
6. To finish the bag, leave four (4) folds left on the bagger. Stop filling, stop PTO and
hydraulics.
On auger units remove the auger.
Drive ahead slowly until the machine is just out of the bag. The end can be closed off the
same way it was started, or the plastic can be folded over and put dirt over top to keep the
wind from blowing the bag open. (Figure 4)
Figure 4
7. Take two (2) pieces of patching tape and place them in a cross configuration at one end of
the bag. Cut about a dime size hole in the center of the cross. Let the bag vent for one (1)
day and then seal the hole with another piece of patching tape.
Your bag is now complete.
Important! When opening the bag, always cut around the bag, never lengthways.

MAINTENANCE
1. When the bag is full and has been properly closed it will require a minimum amount of
maintenance. It is advised that a periodic check be made around the bag to check for any
holes that need to be patched. Good rodent control is a must, so keep spilled feed to a
minimum when filling to prevent rodent attraction to the location.
OPTIONS
1. When filling bags with a highly floatable product such as shell corn, corn gluten, small
grains or pellet fertilizer etc., ROTO-PRESS has a kit available that makes this type of
bagging much easier. The shell corn kit is a complete bolt on kit available from the factory.
For further details, see the enclosed diagram at the end of this manual or consult the factory.
2. ROTO-PRESS has a dual kit available for working in wet fields or spongy ground, adding
greater floatation. For further details, see the enclosed diagram at the end of this manual or
consult the factory.
3. If you add silage preservative in your bagging program, ROTO-PRESS has the set-up for
you. If using a liquid inoculate, your ROTO-PRESS is already equipped with a pipe
coupling welded into the side of the u-through. If using a pellet inoculate, there is a bolt on
Gandy applicator kit available, complete with wire harness. For further details, see the
enclosed diagram at the end of this manual or consult the factory.
4. A conveyor flow control is also available to level out the product in the conveyor. This is
used in conjunction with the silage preservative.
5. For greater compactness, a brake assist & chain installation kit is available.
