摘要
A row following guidance device connecting the right and left ends of the forward portion of a row crop implement to a tractor will adjust the length of each left and right connection as the tractor deviates laterally from alignment with the crop rows to correctively guide the implement in alignment with the crop rows. A row following wheel signals a steering valve upon any lateral deviation of the implement from crop row alignment, the steering valve correcting the deviation by lengthening one connection between the tractor and the implement and shortening the other. The row following wheel is mounted for movement independent of the implement so that the implement may be raised or lowered without affecting the operation of the wheel.
