The Grapple Bucket/Rake attaches to wheel loaders as a pin-on attachment, and is also compatible with JRB's Quick Coupler System. Five models range in size from 2.25 to 6 cu. yds. with maximum openings from 75 to 120 in. The "C" shaped radial design allows unwanted small debris to drop out through the bottom shell. Dual hydraulic cylinders enable the left and right grapple arms to move independently to better support and transport uneven loads. Multi-line grapples equipped with both horizontal and vertical bars hold materials firmly in place.
