Abstract
The automatic steering of the vehicle has a mechanical sensor (124) which follows floor mounted guides (126) and which operates on a hydraulic compensating circuit linked to the servo steering. The system caters for any drift from the guide setting as well as the rate of drift to ensure a rapid and responsive steering control. The totally hydraulic control ensures that a simple, maintenance free system is provided suitable for agricultural vehicles. No electric servo control is required.
