An apparatus for pulverizing and spreading the gravel ridge formed by plowing the shoulder portion of a gravel road onto the travelled portion thereof includes a frame for towing behind a vehicle, vertically adjustable rear wheels on the frame, and a pair of hydraulically driven, transversely extending, blade carrying drums. By towing the frame along a gravel road while rotating the drums, the paddle-like blades pulverize and spread the gravel ridge. |
