AutoTrac Universal 300 Assisted Steering System

Typical faults:
The vehicle has difficulty staying on course
Disengagements during use
The engine does not work

The code OE PFA12421 commonly identifies the steering wheel/actuator of the AutoTrac Universal 300 (ATU 300) kit. The kit is intended for “hands-free” automatic steering on agricultural machines that do not have the factory-integrated AutoTrac option. It is a solution installed on the steering column and, working together with compatible monitors (displays) and GNSS receivers, allows maintaining the set trajectory, reducing overlaps, operator fatigue and pass-to-pass variability, which are essential in precision agriculture.

Technical features

• Electric steering wheel kit for retrofit (ATU 300), designed for machines not equipped for integrated AutoTrac.
• Compact design with a quieter motor compared to the previous ATU 200 generation.
• Weather-resistant design, usable on outdoor operator stations when supported by the compatible display setup.
• Improved diagnostics and simplified calibration procedure to speed up setup.
• Operational compatibility depends on the mechanical condition of the vehicle's steering

DIPA can service these components thanks to its experience and expertise.

Functions

• Automatic guidance on lines and tracks (A-B and display/activation-dependent modes), with line tracking and steering corrections.
• Adjustment parameters to tailor the system response to the platform.
• Line acquisition sensitivity.
• Line accuracy relative to the setting.
• Line accuracy relative to the set direction.
• Curve accuracy when using curved trajectories.
• Steering play management with partial compensation for tolerances and backlash.
• Steering asymmetry management on vehicles that do not steer the same to the right/left.
• Basic diagnostics with status readings

Model applications

• Universal application on a wide range of agricultural vehicles such as tractors, sprayers, combines and other compatible equipment

Typical faults

• The vehicle has difficulty staying on course
• Disengagements during use
• The engine does not work

Final conclusions

The OE PFA12421 steering-wheel system, which is part of the AutoTrac Universal 300 (ATU 300), is a retrofit solution designed to extend automatic steering to machines not equipped with integrated AutoTrac. Its key points are integration with compatible displays and receivers, guided calibration with advanced diagnostics, and improved performance compared to the ATU 200.
