ABSTRACT:
The ground sweeper has an endless screen movably supported upon a screen carrier which is attached to a wheeled trailer chassis such that the screen run makes an acute angle to the ground. A hydraulic motor powered hydraulically from a hydraulic pump run by the power takeoff unit of the pulling tractor rotates the screen drive roller. Hydraulic cylinders actuate a pivotally mounted rear hopper such that it may be hydraulically tilted to dump its load from the screen on the ground. The trailer ground sweeper carries its own hydraulic fluid tank and its hydraulic system has controls operable from the driver's position on the drawing tractor. A scoop at the front of the sweeper adjacent the lowest portion of the moving screen has a scoop blade which is reversible with respect to the run of the belt, such that the blade may be reversed to maintain a keen edge. Preferably the front or lower screen roller is combined with a rock auger such that solid debris coming through the screen may be transversely removed from between the runs of the screen.
