ABSTRACT:
The implement includes a bucket having a lower scraping blade. A pair of laterally spaced ground-engaging wheels are pivotally supported on the rear of the bucket and may be swung upwardly and downwardly in unison to change the elevation of the bucket. One of the wheels may be shifted upwardly and downwardly relative to the other wheel to tilt the implement about a fore-and-aft extending axis and thereby enable the bucket to work at various inclinations.
