Abstract
A rotating drive wheel assembly for steering and maneuvering a dredging apparatus includes a carrier wheel and an orientation wheel connected to opposite ends of a pivotation member. A plurality of spade devices are connected to the wheels, each including a blade portion pivotally coupled to a spoke plate of the carrier wheel, and an arm portion pivotally coupled at opposite ends to the outer portion of the carrier wheel and another carrier wheel spoke plate member. The construction of the present drive wheel assembly allows the spade devices to remain in a substantially vertical orientation when the carrier wheel is rotated about its axis of rotation.
