Page 10: Selecting The Correct Installation For Your Hydraulic Steering System
Page 4 | GPSteer User Guide Selecting the Correct Installation for Your Hydraulic Steering System Your hydraulic steering system may be one of two types: closed center or open center. A closed-center hydraulic steering system allows the tractor to handle pressure build-up in the steering system. This means that there can be blockages in the line or changes in pressure and the pump will compensate.
Page 11 Getting Started | Page 5 However, if you do need to tie into an open-center hydraulic system, it is extremely important to also add a flow-regulating mechanism to avoid damage to your vehicle. GPSteer may be integrated into both closed-center and open- center systems.
Page 12: Additional Installation Considerations
Page 6 | GPSteer User Guide Additional Installation Considerations There are many makes and models of agricultural vehicles. The additional installation considerations described below may or may not apply to your particular vehicle.

Page 21: Connecting The Hydraulic Components
Connecting the Hydraulics | Page 15 Connecting the Hydraulic Components Connecting the GPSteer hydraulics to your vehicle involves the following six steps: Install the GPSteer Valve Block. Install the Shuttle Valve. Install the Left and Right Steering Hoses. Install the Tank Return Line. Install the Pump Pressure Hoses.

Install the To install the GPSteer Valve Block: GPSteer Valve Block Find a desirable location in either the engine compartment or the back of the vehicle to mount the valve block. Warning! When determining a mounting location, it is important to leave enough room for the cable and hose connections.

Install the To install the Shuttle Valve: Shuttle Valve Locate the Load Sense line to find the optimal mounting loca- tion for the Shuttle valve. Locate the Load Sense (LS) Hose: Shuttle-to-GPS Valve (#6 ends).
Page 25 Connecting the Hydraulics | Page 19 Connect the other end of the hose to the port on the GPSteer Valve Block, labeled “LS”. Secure the Shuttle Valve using tie wraps if necessary. Locate the tractor’s Load Sense hose (see below - the pen in the photo is pointing to the Load Sense hose).
Page 26 Page 20 | GPSteer User Guide Disconnect the Load Sense hose from the pressure- compensated device (usually the pump) and reconnect to the side of the Shuttle Valve. Step 7.

Page 43: Additional Installation Considerations
Connecting the Hydraulics | Page 37 Additional Installation Considerations Additional installation considerations include: • reactionary steering - if your wheels turn when you turn the vehicle’s steering wheel, you have reactionary steering. You must install a Counter-Balance valve (optional accessory available through Satloc) in between the steering cylinders and the steering unit in order to block oil from flowing back into the steering unit from the steering cylinders.
Page 44 Page 38 | GPSteer User Guide If you have non-reactionary steering, the steering wheel does not turn when the wheels turn. If you have non-reactionary steering you can skip this section. If you do have reactionary steering, you must install a Counter- Balance Valve in between the steering cylinders and the steering unit.
Page 45 Connecting the Hydraulics | Page 39 Figure 2-3. A Counter Balance Valve Is Installed In Between the Steering Unit and Steering Cylinders on both Open- and Closed-Center Systems with Reactionary Steering. Part Number: 875-0139-000...
Page 47: Pressure Regulation
Connecting the Hydraulics | Page 41 Pressure Regulation If the steering pressure is significantly less than the pressure delivered from the pump, you may need to install a Pressure Reducing Valve [optional accessory available through Satloc - Part Numbers 750-0034 (valve) and 750-0036 (connector)]. For instance, the John Deere 55 series tractor uses a closed-circuit steering system that operates with significantly less pressure than what is available from the main pump.
Page 48 Page 42 | GPSteer User Guide To install the Pressure Reducing Valve and connector: Insert valve in the GPSteer-to-Pump line. Connect Port 3 to the pressure line. Connect Port 1 to the tank line. Connect Port 2 to the “P” port on the GPSteer Valve Block. ©...

Chapter Calibrating GPSteer Overview Calibration Settings...
Page 58: Overview
Page 52 | GPSteer User Guide Overview Your GPSteer calibration needs will depend on your vehicle and the conditions under which you are farming. The primary method for calibrating GPSteer is to adjust the Needle Valve on the GPSteer Valve Block. Once the Needle Valve has been adjusted, there are typically two controller settings you may need to adjust: proportional band and sensitivity.
Page 59: Valve Block Calibration
Calibrating GPSteer | Page 53 Valve Block Calibration The Needle Valve on the GPSteer Valve Block should be your first and primary method of calibrating GPSteer. Figure 4-1. Needle Valve on the GPSteer Valve Block. Adjusting the Needle Valve allows you to adjust the flow rate from high to low.

Page 61 Calibrating GPSteer | Page 55 • Gain Setup - Gain setup offers parameters that adjust the steering in unique circumstances. There are three adjustments you may make for Gain: • Integral Gain: 0.0 to 100.0 with 0.0 as the default. Increase this value to get less steady-state error, but also less stability.
Page 62: Calibration Procedure
Page 56 | GPSteer User Guide Calibration Procedure Calibration must be performed: • after performing the valve test to confirm that the installation is correct (see “Chapter 3: Installing GPSteer”) • with tight, properly functioning linkage and steering hydraulics • on a hard, flat surface (rough or uneven surfaces will make it difficult to calibrate) •...

When adjusting the needle valve, turn the valve clockwise (open) or counter clockwise (closed) in 1/4 turn increments. About four complete turns will open or close the valve.

Page 67: Set The Proportional Band
Calibrating GPSteer | Page 61 2. Set the Proportional Band After setting the flow rate, you may need to set the proportional band. The proportional band default setting is 5. Increasing this value will stabilize the steering, but decrease responsiveness. Decreasing this value will have the opposite effect.
