ABSTRACT:
A leaf grapple for grabbing and lifting a pile of leaves or other loose debris is disclosed. The leaf grapple includes a basket at the end of a handle. The basket has multiple sections, each section being movably attached at the top to a first spider and, some distance away from the top, pivotably attached to a second spider. An actuating rod is assembled in the handle. The first spider is attached to the end of the actuating rod; the second spider is attached to the end of the handle. Pushing on the handle forces the first spider downward, which forces the top portions of the grapple sections downward. The grapple sections pivot about the lower ends of the second spider, which causes the grapple sections to open. Pulling up on the actuating rod forces the grapple sections to close.
