Abstract
An attachment with a back support frame adaptable for use with a variety of loaders for use in tree removal and field reclamation. The back support frame has a curved front wall serving as a moldboard and a bottom wall with a cutting edge for grading dirt. A stationary lower jaw generally trapezoidal in plan is attached to the back support frame and is made of a plurality of cross braced blades forming a see-through grid through which dirt may be sifted with spade-tipped teeth at a distal end for digging and replaceable strips of saw teeth on the outer blades for ripping tree roots. A movable upper jaw with obliquely mounted grapple arms is mounted on the back support frame and is independently movable towards and away from the stationary lower jaw for applying three-point pressure to a root ball or tree trunk.
