ABSTRACT:
A wheel mounted pull type chassis includes a side hitch bar for securement to a tractor or the like. A reel assembly is journalled for rotation and is situated transversely at the front of the chassis and picks up rocks, stones, dirt, etc. and deposits same on an upwardly and rearwardly inclining slotted apron with the teeth of the pick up bars at the reel passing through the apron teeth and depositing the picked up material into a screening wheel journalled for rotation about a generally horizontal but inclined longitudinal axis so that the wheel is tipped rearwardly from the vertical. The periphery of the wheel is slotted. It is supported upon a pair of spaced apart support wheels one wheel of which is driven and which engage a track around the outer periphery of the wheel. Three equidistantly spaced rear support wheels engage the rear of the periphery of the wheel for added support. The dirt and small stones sift through the slotted periphery of the screening wheel as it rotates and the larger stones and rocks are carried upwardly by the interior of the wheel to be dropped vertically from the upper side of the wheel into a drum type container also carried in the chassis rearwardly of the wheel but having an open upper side veritcally below the upper side of the screening wheel.
