Plug and Orifice Functions
• 13A = An orifice installed here will bleed LS pressure from the LS OUT port to tank to de-stroke the pump.
• 13B = A plug installed here will isolate the LS ORBITROL port from the LS OUT port. This plug must never be installed
for Closed Center LS Orbitrol applications because it will block the flow of LS oil across the valve.
• 13C = This plug isolates the internal LS circuit from tank and must always be installed for all applications.
Steering Valve Bracket Installation
The AutoFarm kit includes two universal valve brackets and metric hardware to fit most vehicles using existing attachment
points. The brackets offer holes and slot features to accommodate a variety of bolt spacings on the machine. See
Figure 3-7.

Valve Installation Guidelines
1. Install the valve on the vehicle in a position that is protected from tall crops and debris.
2. Install the valve in a position that will allow good hose routing and short hoses to the hookup points on the vehicle.
3. Install the valve in a position that does not interfere with the normal operation of moving parts on the vehicle such as cov-
ers, removable shields, wheels, lift arms and implements.
