ABSTRACT:
A tractor drawn scraper apparatus with folding wings includes a main frame with a main blade assembly depending therefrom and wing frames with wing blade assemblies depending therefrom. The wing frames are pivotally connected to laterally opposite ends of the main frame and are pivoted by the action of hydraulic cylinders connected between the main frame and the wing frames respectively. The wing frames are lowered for soil engagement and raised for transport. A wheel frame includes a wheel frame axle pivotally connected to the main frame by way of the main blade assembly and having a pair of radial wheel support arms with ground engaging wheels journaled thereon. A pair of wheel frame cylinders engaged between the main frame and the wheel support arms are activated to raise the wheels for soil engagement by the blade assemblies and to lower the wheels for transport. A tongue assembly extends forwardly from the main frame for hitching to a tractor to draw the blade assemblies over a soil surface.
