ABSTRACT:
A guidance system for an agricultural tractor includes a furrow feeler which depends from a horizontal shaft so that the shaft rotates about a horizontal axis aligned with the direction of draft. Misalignment causes rotation of the horizontal shaft, which through arms and switches causes an electric motor to turn in a first or second direction as is appropriate to cause the tractor to follow the furrow. The motor is connected by suitable transmission to a yieldable tire which engages the steering wheel of the tractor so that rotation of the tire from the motor will cause the tractor to be steered from the steering wheel. A gauge wheel forms a track furrow so that in future operations, the tractor follows the precise path as before.
