1. Auto Guidance Systems.
By Adam Wood

2. Assisted Steering Systems.
Auto steering uses Global Positioning System (GPS) to guide the sprayer through the field.
Electro hydraulic steering is required.
This can be factory installed or bought as an aftermarket ad-on.

3. Here's How Auto Steering Works.
Set the first pass (Track 0) from the In cab display.
The system will "draw" lines that are parallel to Track 0.
Simply press a button on your tractor's Command Arm, and AutoTrac will steer your tractor down these parallel lines.
Once you are at the end of the row simply turn the tractor around press the Resume switch on the tractor’s Command Arm and let go of the wheel.
