Abstract
A tractor includes an internal combustion engine and is adapted for underwater operation, with inlet and outlet means extending to above the surface of the water for supplying air to the engine and exhausting combustion gas therefrom. A dredging implement in the form of a blade and auger, directs material from the floor to adjacent one end of a conduit means as the vehicle is transported over the floor. An impeller associated with the conduit means transports the material therethrough and from the other end of the conduit means, which is positioned above the surface of the water. The dredging implement may alternatively take the form of a pair of wing members, each angled upwardly and inwardly in the rearward direction to direct material to adjacent the one end of the conduit means. Means remote from the vehicle, and positionable on shore, are included for operating the submerged tractor.
