Two pincer bucket halves, each including a horizontal blade, are mounted on a frame for opposed pivotal movement in a normally horizontal plane about respective parallel normally vertical axes. An upstanding back spans the axes and upstanding sides extend perpendicularly from the outer edges of the pincer blades. To pick up material, such as a pile of leaves or branches, from a ground surface, the pincer bucket halves are opened and advanced toward the pile with the opposed blades in contact with the ground surface. After the bucket halves are located on opposite sides of the pile, the bucket halves are brought together so that the blades are closed, thereby undercutting and supporting the material, with the vertical sides of the buckets confining the material in combination with the vertical back. The embraced material may then be elevated and transported within the bucket. The material is discharged by tilting the bucket forwardly and opening the bucket halves. As a modification, the two bucket halves may be pivoted about a single vertical axis.
