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

Remove the cab roof bolts.

3

Align the mounting rail to mounting holes and fasten the mounting rail to the roof using the longer bolts and spare washers provided in the installation kit. The lettered holes and the dummy cable connector must be on the left side of the tractor.

7. Install the Hydraulic Hoses

7.1 Assemble the Hydraulic Hoses

Assemble hoses as shown (Hose length is not shown to scale below.)

7.2 Route the Hydraulic Hoses

Summary: Steer IN and OUT hoses are routed from the hydraulic valve, under the cab, to the vehicle’s steering valve assembly.

Note: Secure the hoses with cable ties and be sure they are clear of moving parts and heat sources.

7.4 Connect the Hydraulic Hoses

Connect the hoses as shown in the figures below.

Install the AutoFarm shuttle valve as shown here. The center port connects to the Load Sense hose on the tractor. One side port connects to the Steel Load sense line coming from the manual steering unit. The other side port connects to the thin hose coming from LS on the AutoFarm valve.

Install a tee on a the original pressure line going to manual steering and connect the AutoFarm pressure hose to this tee.

The AutoFarm valve shares the pressure, return, and load sense lines used for manual steering. Install a large tee to the original return line coming from the manual steering unit and connect the AutoFarm return hose to this tee.
