Hardware Installation Guide 3
Installation Types
• Vehicles with sloppy steering systems or that are in poor mechanical condition.
• Vehicles with poor electrical systems
• Vehicles with unconventional steering systems
We recommend the following Steps before considering a new vehicle for an AutoSteer installation:
• Obtain a copy of the vehicles hydraulic diagram to understand how the steering system and steering pump works. The
hydraulic diagram is usually available in the vehicle's shop manual or may be purchased from the vehicle dealer.
• Determine if the steering system is Closed Center with Load Sense or Open Center.
• Inspect the vehicle and determine if the hydraulic setup matches the manufacturer's hydraulic diagram.
• Inspect the vehicle to confirm that it offers attachment points for the AutoFarm Monitor, GPS Roof Module, wheel angle
sensor, valve and hydraulic hoses.
• Drive the vehicle in a small circle at slow speed and let go of the steering wheel to determine if it is non-reactive steering.
Non reactive steering will maintain the steering wheel steady and the vehicle will continue in a circular path. Reactive
steering will allow the wheels to slowly return to center position while the steering wheel turns slowly without input from
the driver.
• The AutoSteer kit described in this manual must only be installed on vehicles with non-reactive steering systems.
• Drive the vehicle and check for sloppiness in the steering system and check if it pulls to one side. The vehicle must steer
straight and the steering must be firm and responsive.
• Check if a 12V power outlet is available and plan ahead for alternative electrical power connection. Measure the voltage
at the power outlet using a multimeter
Installation Types
This installation guide describes the installation of the AutoFarm AutoSteer systems using the AutoFarm compact steering
valve assembly for the following hydraulic installation types:
• Orbitrol Closed Center Installation
• Orbitrol Closed Center with Power Beyond Connections
Note: Do not attempt to install the valve on hydraulic systems that are not covered in this manual.
Orbitrol Closed Center Installation
Correct Installation Types
• Installation where the vehicle has a closed center non reacting Orbitrol with a Load Sense line. The closed center Orbitrol
may get its oil supply from a variable displacement pump or a fixed displacement gear pump with a LS steering priority
valve.
• Installations where the Orbitrol uses conventional Load Sense or Dynamic Load Sense.
Incorrect Installation Types
• Vehicles with reactive (self centering) steering system.
• Very large vehicles that require a higher oil flow and a larger AutoSteer valve.
• Vehicles with an Open Center steering system.
• Pressure compensated steering systems without an Orbitrol Load Sense hose.
