ABSTRACT:
A bucket is pivotally mounted on the movable arms of a tractor. A closure member having a first closure member side and second closure member side is pivotally mounted to the bucket with the first closure member side pivotally mounted to the first bucket side and the second closure member side pivotally mounted to the second bucket side. The closure member may be moved to form an enclosure with the bucket or the closure member may be moved back over the bucket so that the bucket may be used conventionally. A first closure member extensible hydraulic ram and second closure member extensible hydraulic ram are provided to move the closure member through a cable apparatus. The closure member front portion is concave in shape so that when the closure member is fully forward the apparatus may be used for conventional bulldozing, grading and the like.
