Caution Alerts
Caution Alerts indicate potentially hazardous situations that if not avoided may result in minor to moderate injury. Caution
Alerts may also identify unsafe installation practices.
CAUTION
The roof module must be removed when transporting or
driving the vehicle at speeds above 30 mph (50 km/h). The
roof module can possibly detach due to wind loads at
higher speeds.
CAUTION
The GPS steering system does not detect obstacles in the
vehicle’s path. The operator must observe the path being
driven in order to avoid obstacles.
CAUTION
When engaged, the GPS steering system controls only the
steering of the vehicle. The operator must control the speed
of the vehicle.
CAUTION
The supplied roof module locking pin or a padlock must be in
place whenever the vehicle is in operation to prevent the
roof module from releasing from its bracket.

Hardware Installation Guide vii
Important Information
Vehicle Requirements
The vehicle steering system and hydraulic system must be in good working order before installing the AutoFarm system.
Check for loose or worn parts. Drive the vehicle before installing the Autofarm system and confirm that it steers straight and
the wheels can be turned from lock to lock. Check the steering system hydraulic hoses and connections to ensure there are no
oil leaks.
The vehicle electrical system and battery must be in good working order.
We recommend that the vehicle be fully cleaned with a high pressure washer before installing the AutoFarm system. A clean
vehicle will facilitate the overall installation and cable routing and will also reduce the chance for oil contamination when the
hoses are opened. It is important to clean the area around the power beyond, front axle, frame, under the cab and behind the
rear cab shields.
Important Information
Note: Tighten all screws, bolts, nuts, hose connections and cable connections after the final assembly of the AutoFarm
Steering System on the vehicle. Follow the checklist at the end of this manual before returning the vehicle to service.

Introduction
This manual provides information for completing an AutoSteer installation on wheeled farm vehicles that are not supported by
Autofarm vehicle specific installation kits. A working AutoSteer installation requires brackets and hoses that correctly fit the
vehicle. This manual provides guidelines, specifications and examples of typical AutoSteer installations with the purpose of
helping AutoFarm dealers accomplish a working installation that will perform satisfactorily and be safe.
This manual does not cover all possible types of vehicles or even nuances that exist between different brands and models of
farm machinery so it is the responsibility of the installer to determine if the installation will correctly fit the vehicle and
perform in a safe manner.
Do not attempt this installation if you have not received training for the AutoFarm A5 product installation and if you have not
completed at least ten standard AutoFarm kit installations. Do not attempt this installation if you do not have complete
information and familiarity with the vehicle's steering system and hydraulic system. The installer assumes all responsibility for
using good judgment and good fabrication practices when performing this installation.
Installation Guidelines
1. Understand the type of steering system that is used on the vehicle where you will be installing the AutoFarm valve.

2 AutoFarm GPS AutoSteer
Introduction
2. Refer to the hydraulic schematic of the vehicle steering system (often found in the shop manual) to determine what type of
steering is used on the machine.
3. Do not install the valve on steering systems that are not specifically covered in this manual.
4. Do not install the valve on highway vehicles. Only install the valve on slow speed off-road agricultural vehicles.
5. Install the valve in a position that is easy to access and service.
6. To complete the installation you will have to make at least six custom hoses. The hose lengths will be determined by where
you install the valve on the machine. If possible, install the valve close to the connection points on the machine.
7. All hoses that connect to the AutoFarm valve must use O-Ring Face Seal (ORFS) type hose fittings.
8. All hoses that connect to the machine must have hose fittings that match the type of fitting used on the machine (ORFS,
JIC, Metric etc.).
9. Use only high quality hydraulic hose rated for 3000psi or more.
10. Only use hoses and fittings from the same manufacturer. Do not mix hoses and fittings from different manufacturers.
11. All hoses must be crimped per the fitting manufacturer’s recommendations using the recommended crimping tool.
12. Clean hoses inside after assembly using a blast of compressed air to eliminate all contamination.
13. Cover the hose ends to avoid contamination during the installation on the vehicle.
14. Confirm that all hoses are connected to the correct points at both ends before starting the engine.
15. Confirm that all hose fittings are tight before starting the engine.
16. Route hoses clear from moving parts or hot parts on the vehicle. Secure all hoses in a safe and protected position.
17. Use an oil pan or bucket to collect oil when hose connections are opened. Clean all oil spills immediately.
18. Follow all safety recommendations outlined in this manual and good shop practice.
Vehicle Requirements
A vehicle must meet the following requirements before it is considered for an AutoSteer installation per this manual:
•The vehicle must be a slow speed off road farm vehicle that does not exceed 30mph at top speed.
•The vehicle must be a wheeled vehicle that runs on three or more rubber tires.
•The vehicle must have a hydrostatic steering system comprised of a steering Orbitrol, one or more steering cylinders, and
a hydraulic pump.
•The vehicle's steering system must be in good running order without excessive play or leaks.
•The steering system must be non-reactive (non-centering)
•The vehicle must have a 12Vdc power outlet in the cab or 12Vdc battery available.
•The vehicle must have only one steered axle
•The vehicle must offer a cab or structure for antenna mounting purposes
Do not install the AutoSteer kit covered in this manual on the following types of vehicles:
•Highway vehicles or high speed vehicles such as cars, pickups or trucks.
•Vehicles with reactive steering (self centering)
•Vehicles with a secondary steered axle such as rear wheel auxiliary steering.
•Vehicles that run on tracks.

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.

4 AutoFarm GPS AutoSteer
AutoFarm Installation Kit Overview
Orbitrol Closed Center with Power Beyond Connections
Correct Installation Types:
•Installations where the vehicle has a closed center non reacting Orbitrol with a Load Sense line and a power beyond system
available. The power beyond system must have pressure, tank and LS ports available. The closed center Orbitrol may get
its oil supply from a variable displacement flow and pressure compensated pump or a fixed displacement gear pump with
a Load Sense steering priority valve. This installation is preferred and can be simpler to install when the tractor has a power
beyond system available.
Incorrect Installation Types:
•Vehicles with reactive (self centering) steering system.
