Auto Guidance Systems. By Adam Wood

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.

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.

Accuracy Within Each System. AutoTrac Option Recommended Application  Accuracy  AutoTrac SF1    Tillage, Pull-Behind Sprayer, Air Seeding  +/- 13-in. AutoTrac SF2    Planting, Self-Propelled Sprayer, Broad-Acre Harvesting  +/- 4-in. AutoTrac RTK  Bedding, Strip Till, Drip Tape Irrigation     Repeatability Sub-Inch Repeatable

Benefits of Auto Steering. Reduce Operator Fatigue More comfortable working hours Increased awareness of machine functions Optimize Machine Efficiency Operate at faster field speeds Reduce per acre fuel consumption Reduce overlap on implements and sprayers Increase Yield Cover more acres with fewer hours of operation Centralize compaction due to planned traffic patterns on fields More accurate placement of agronomic inputs such as fertilizer and herbicides

Disadvantages of Auto Steering. PRICE $$$$
