ABSTRACT:
The present invention relates to a steering device for facilitating the steering of an implement towed by a work vehicle. The towed implement, for example, a farm implement such as a seeding device, comprises a main frame having front and rear ends and at least one steerable surface engaging wheel attached to the frame. The steering device comprising a sensor means mounted on the main frame of the towed implement for sensing a misalignment of the towed implement and the work vehicle and producing a signal corresponding to the misalignment. The steering device further comprises a steering means associated with the steerable wheel for receiving the signal produced by the sensor means and for effecting movement of the steerable wheel in response to the signal until the towed implement and the work vehicle are once again realigned.
