Abstract:
A dirt contouring and grading device final grading of a soil bed prior to sodding includes a vehicle, which in turn comprises a frame, a plurality of wheels, and a propulsion unit so that the vehicle is self-propelled. A deck that is engaged to the frame has a drum engaged thereto. The drum is operationally coupled to an actuator that is powered to selectively effect axial rotation of the drum against a surface upon which the vehicle is positioned. A first biaser is powered to selectively raise, lower, and angle the deck relative to the frame to create flat sections, gentle hills, and mounds in a soil bed. A second biaser is powered to selectively effect longitudinal rotation of the drum relative to the deck to direct excess soil selectively to one side or the other of the vehicle.
