Description

Agra-GPS RetroSteer – Hydraulic Autosteer Retrofit  for every Machine

The Agra-GPS RetroSteer hydraulic autosteer kit upgrades older or non-prepared vehicles—tractors, combines, forage harvesters, and more—to full automatic steering capability.

Instead of a bulky and noisy steering wheel motor, RetroSteer integrates a compact hydraulic steering valve and a wheel angle sensor directly into the machine’s existing steering hydraulics.
Paired with the Agra-Bridge, your machine is recognized as a John Deere vehicle and can use full JD AutoTrac™ functionality on a wide variety of brands.

How It Works

Hydraulic Steering Valve
A compact, machine-adapted valve is integrated into the existing hydraulic steering circuit.

Wheel Angle Sensor
Continuously monitors the steering position of the front wheels for high-accuracy control.

Agra-Bridge + John Deere Display
The Agra-Bridge makes the machine appear as a JD steering-ready model. The operator uses the familiar John Deere interface, full AutoTrac™ functions, and standard workflow.

Manual Override
The driver can take over steering at any moment. The installation is completely reversible.
