Abstract
Apparatus suitable for mounting on a tractor, and capable of providing opposed movement to a pair of cooperating implements suitable for digging or lifting. The apparatus has a frame with an upper central region and two laterally spaced lower regions, and two movable arms, each capable of holding one of the implements. Each arm has an inner end pivoted to the frame at one of the lower regions by a pivot which restricts movement of the arm, relative to the frame, to an inclined pivot plane, the pivot planes being situated to both slope downwardly and inwardly and meet at a line of intersection which is below and symmetrically between the pivots. A linkage arrangement is provided connecting the central upper region of the frame to each arm, and power cylinders are provided for moving the arms in their inclined pivot planes.
