GROUND-RAKING, ROCK-GATHERING ATTACHMENTS FOR TRACTORS Abstract of the Disclosure A bucket mounted ground-raking and rock-gathering attachment is picked up off the ground following rock- gathering, by operation of hydraulic cylinders on the tractor provided for lifting and lowering the bucket. The tractor is then driven to a dumping site whereat the outer end of the attachment is set down onto a pile of debris or other elevated surface to be supported thereby. Then, hydraulic cylinders on the tractor are operated to rotate the bucket, for dumping the debris, while the attachment is substantially maintained in position. A passive tension strap, inter- connected between the top of the bucket and the top of the attachment to limit the extent of downward pivotal movement of the attachment relative to the bucket, bends to permit such dumping rotation of the bucket. In a second embodiment, a second passive tension strap, interconnected between a top portion of the attachment and an upper portion of the bucket support frame, holds the attachment in a substantially level position while the bucket is rotated to dump debris. -1-
