2. Install Roof Module
2.1 Safety Notes
The AutoFarm system must be powered OFF when installing or removing the roof module.
The supplied locking pin or a padlock must be in place whenever the vehicle is in operation.
The roof module must be removed when transporting the vehicle at speeds above 30 mph.
Make sure that you are in a stable position on the tractor platform when removing the roof module, so that
you do not fall or drop the roof module.
2.2 Install the Mounting Rail
Mount the roof module brackets on the four screws on the cab roof as shown below. Replace the four screws
shown below by the four longer screws provided in your kit.

Attach the radio modem antenna. Note: The antenna should be attached “hand tight.” Do not use any tools
to tighten the antenna. Apply a small amount of silicone grease to the o-ring seal on the antenna before
mounting on the roof module.

3.5 Adjust the Sensor and Linkage Arms
Adjust linkage arm length and/or linkage bracket position to obtain between 3200 and 3800 counts. Turn the
wheels all the way in both directions to make sure the linkage arms can move without interference. Note:
This step is done during the calibration and tuning steps. Adjust the wheel angle sensor by rotating the
sensor after loosening the two socket head screws with an Allen Key wrench.
Route the wheel angle sensor cable along the left side of the combine frame and secure with cable
ties.(Keep all cables away from moving parts.).

4. Install the User Terminal
4.1 Assemble and Mount the User Terminal Bracket
The user terminal will be installed under the door frame on the right side of the cab. You will use the special
screws provided in your kit to secure the bracket under the door frame. Mount the slider plate on steel
bracket in the position shown above.

Choose a position for installing the bracket under the door frame. Move the user terminal forward and
backward to find the best position. The driver should be able to reach the touch screen and emergency stop
button while seated. The user terminal should not obstruct the driver’s view of the platform.

Drill five 13/64” holes for the screws using the bracket as a template. We recommend drilling one hole to
secure the bracket with one screw before drilling the remaining holes. The holes should be drilled so that the
bracket mounts in the position shown below when looking at the right side door from inside the cab.
CAUTION: Use safety glasses to prevent eye injury while drilling.
