The remote hand held controller has six functions:
1. OFF BUTTON - used to stop movement and to de-energize the remotes
transmitter. Once the remote OFF button has been pressed the remote will not
be able to send a signal to the receiver and control box. If the OFF button on the
remote was used you can only move the hopper with the hard wired control box.
The remote will only function again after the ON button is pressed.
2. ON BUTTON - used to energize the remote transmitter and receiver. Once
pressed the remote transmitter can send the signal to the receiver to accept
commands. If pressed again, the work light will turn on. Press the ON button
again to turn off the work light.
3. MANUAL LEFT - moves hopper left while button is pressed and held.
Movement stops when the button is released. Press and hold button again and
movement starts again.
4. MANUAL RIGHT - moves hopper right while button is pressed and held.
Movement stops when the button is released. Press and hold the button again
and movement starts again.
5. AUTOMATIC LEFT - moves hopper left automatically. When the button is
pushed and released, the movement starts and continues automatically until the
hopper reaches a predetermined limit stop, the OFF button is pressed, or any
other button is pressed and released.
A. The remote system stays energized after the automatic movement
stops from reaching the predetermined limit stop.
B. The start button will have to be pressed to re-energize the remote
system if the stop button was used to stop the automatic movement.
C. The remote system stays energized when the manual left or manual
right buttons are used to stop the automatic movement.
D. Auto Left cannot be activated again until Auto Right is activated.
**The remote is now ready for the next command.
6. AUTOMATIC RIGHT - moves hopper right automatically. When the button is
pushed and released, the movement starts and continues automatically until the
hopper reaches a predetermined limit stop, the OFF button is pressed, or any
other button is pressed and released.
A. The remote system stays energized after the automatic movement
stops from reaching the predetermined limit stop.
B. The start button will have to be pressed to re-energize the remote
system if the stop button was used to stop the automatic movement.
C. The remote system stays energized when the manual left or manual
right buttons are used to stop the automatic movement.
D. Auto Right cannot be activated again until Auto Left is activated.
**The remote is now ready for the next command.

**IMPORTANT**
1. The predetermined limit stops only stop the movement when the automatic left
or automatic right buttons are used. The manual left and manual right buttons on the
remotes or the hard wired control box, when pressed and held, will override the
predetermined limit stops.
2. Make sure the adjustable limit stops are removed when moving the hopper to the
opposite side of the main auger. This ensures that nothing is broken during moving.
The stops will have to be reset after the hopper has been moved to the opposite side.
3. Limit stop sensors and magnets must always be adjusted to ensure proper shut off
when moving, using the automatic left and automatic right buttons.
** Use only the manual left and manual right buttons or the hard wired box buttons when
moving the hopper over to the opposite side of auger. Never use the automatic
controls.
HARD WIRED BOX
This is the box with the red emergency stop button and also a left and right control
button (joystick). This box will be located on the auger tube above the hopper.
The functions of this box:
- Red Emergency Stop Button - When button is pushed down, it stops
any and all movement of the hopper. To stop movement, press down on
top of the button.
To resume movement from right or left buttons on this box or the remote
this button needs to be in the up position.
To place this button in the up position, twist and the button will pop up.
- Joystick –Hopper will move in the directions the joystick is moved.
IMPORTANT –Moving the joystick will override limit stops.
NOTICE: Just an example of a working demo- You push “AUTO LEFT” to place
hopper under grain trailer. Hopper will stop at a predetermined point when the
limit stop sensor comes in contact with the magnetic field of the limit stop
magnet. If you need to continue to the left you would need to push and hold
manual left to override auto stop and hopper would move more to the left. Be
aware if you continue to the left at some point the stop sensor will go past the
magnetic field of the limit stop magnet. If this happens you will not have any
movement from auto left until hopper is brought back to the right using auto
right. This process resets the safety logic built into the controller.

WARNING:
DISCONNECT the motor cable from the motors to
avoid any damage to electrical components when
pushing the hopper to the other side of the auger.

MOUNTING THE MOTOR AND WHEEL
ASSEMBLIES
HM, H1 and H2 Models
The motor and wheel assemblies can be mounted on either side of the hopper.
Pictures and instructions, used in this manual, are for mounting the motor and wheel
assemblies on the front side of the hopper with the hopper on the right side of main
hopper (standing in front of auger and looking toward the back of the main auger). If
mounting on the left hand side, the procedure is the same. If there is a certain side of
the main auger which is normally used more, use that side for a starting point. If there
isn’t just use a side of your choice.
It is easier to mount the motor and wheel assemblies if the hopper is in transport
position.
Remove existing wheels and axles from the hopper.
On Mayrath/Hutchinson 4 wheel, twin auger hoppers, the middle hole
needs to be enlarged to fit our ¾” drive shaft. The hole should be
slightly oversized so the shaft can move freely.
Install 4 bronze bushing in bushing holder brackets.
Bushing installed in bushing holder bracket.

10
Loosely attach one bushing holder and bushing to hopper as shown below, using a
bushing holder bracket as a support plate on the inside. Two 3/8” x 1-1/4” bolts with
3/8” flat washers and 3/8” flanged nuts attach the bracket to the hopper. The washer
must be under the bolt head.
Loosely install another bushing holder and bushing, with the anti-rotation bracket used
as a support plate, on the holes on the inside plate on the hopper. Two 3/8” x 1-1/4”
bolts with 3/8” flat washers and 3/8” flanged nuts attach the bracket to the hopper. See
picture below.
Install the drive shaft through the outside bushing and slide on two locking collars. The
shaft end with the keyway cut to the end is for the tire and needs to be on the
outside of the hopper when installed.
Bushing holder brackets and drive shaft partially installed.

11
Insert the shaft through both bushings. It may be necessary to loosen the nuts on the
inner bushing holder so the drive shaft will line up with the bushing.
Note the bushings face the same direction.
Adjust the drive shaft so it is centered in the hole on the hopper and tighten the bolts.

Make sure the anti-rotation bracket is centered on the shaft and parallel with the bottom
plate of the hopper.
Tighten remaining bolts.
The shaft should be able to spin by hand fairly easily when adjusted correctly.
Install the tire using 3/16” keystock and set screws for the tire hub. The shaft should be
flush with the end of the hub. Slide shaft in until tire has ½” – 1” of clearance with the
hopper.

Install the inner motor using the 3/16” keystock and 23 RPM motor. Check the name
plate on the motor to make sure the correct motor is installed in the correct location.
Make sure the 3/16” keystock is installed before sliding the motor on the shaft. Use
anti-seize to ensure motor can be removed in the future.
The anti-rotation bracket may need to be adjusted so the top mounting hole on the
motor lines up with one of the holes in the anti-rotation bracket. The inside motor uses
the top hole on the anti-rotation bracket. The outside motor uses the lower hole.
Attach inner motor to anti-rotation bracket using the knob with ¾” of thread.
The outer motor attaches to the plate using a knob with 1-1/2” of thread and a spacer
between the motor and the anti-rotation bracket.
NOTE: Brandt Hoppers will use two knobs with 1-1/2” of thread and two spacers;
one on the inner motor and one on the outer motor.
Slide the locking collars out as far as possible and tighten.

MOUNTING THE TUBE MOUNT
CONTROLLER BRACKET
HM, H1 and H2 Models
Mount the tube mount controller bracket using 2 large hose clamps. The bracket should
be located 24” – 36” from the flange at the end of the swing tube or up to 6’ from the
hopper. Position the tube mount bracket so it is centered on the tube when the hopper
is in working position.
Once the tube mount controller bracket is mounted, loosen one hose clamp enough to
slide a zip tie underneath and retighten the hose clamp. This zip tie will hold the excess
length of the hose clamp. Repeat process for the other hose clamp.
24”-36”

18
MOUNTING THE REMOTE CONTROL
BOX AND BEEPER
HM, H1 and H2 Models
Mount the control box on the controller plate using two ¼” x 1-1/2” bolts and ¼” flanged
nuts. Make sure the connectors on the controller are facing towards the hopper.
The beeper will also get mounted on the bottom of the controller plate to one of the ¼”
bolts used to mount the controller. On HM Models, there will not be a beeper.

19
MOUNTING THE HARD WIRED CONTROL BOX
HM, H1 and H2 Models
Place joystick box into cradle and secure with bungee cord. The large cable will lead up
the swing tube. Connect the gray receiver connector to the gray receiver outlet on
control box. On HM Models, this gray connector will not be connected.
Secure the hard wired control box with bungee cord as shown.
Connect the motor cable attached to the motors to the 8’ lead coming from the joystick
box. When pushing the hopper to the other side of the auger,
unplug this connection to avoid any damage to electrical
components.

20
MOUNTING LIMIT STOP BRACKETS
AND LIMIT STOP SENSORS
H2 Models
This section shows how to mount the limit stop hardware to a Westfield MKX and MK
auger. Other brands of augers will follow the same procedure. Contact Rust Sales,
Inc. if your auger is different than what is shown below.
Install limit stop magnet in long slot on limit stop bracket. The non-threaded end of the
magnet faces down.
Remove bolt or bolts from spout head retainer. Install limit stop brackets so one is on
the front side of the boot above the PTO shaft and the other is on the opposite side of
the boot than the hopper. Depending on auger size and configuration, only one
mounting bolt may be needed to mount limit stop bracket. This will allow the
bracket to be adjusted in or out as needed. Use existing bolts and a supplied washer
on the short slot to install stop bracket. Bracket may need to be adjusted to work
properly.
