Abstract

The device is attachable to the front of a tractor to steer it automatically and comprises a shoe running in the wheel furrow left by the previous run of the tractor and connected by a parallelogram linkage to a vertical shaft on which is mounted a disc. Rollers act on the tractor wheel to steer the tractor. The disc has an annular flange on one face which limits sinking into the ground, and is mounted in a cap mounted on the shaft. The medium plane of shoe and of disc are coincident or parallel. One end of the member can turn around a shaft fixed to a ring free to rotate on the coupling rod.
