Apparatus for mounting on a tractor or other vehicle and providing opposed movement to digging or lifting implements

Apparatus suitable for providing opposed movement to a pair of cooperating implements, comprising;

• a frame having an upper central region and two laterally spaced lower regions;
• two movable arms, each arm having an inner end pivotally mounted to the frame at one of said lower regions by a pivot which restricts movement of the arm, relative to the frame, to an inclined pivot plane, the pivot planes of said arms being situated relative to the frame so that when the frame is vertical both planes slope downwardly and inwardly and meet at a line of intersection which is situated below and symmetrically between said pivots, each said arm having an outer end portion capable of carrying one of said implements,
• two levers each having a central portion pivotally mounted adjacent to said central region of the frame, each said lever having a lower end portion pivotally connected to one of said arms at a location suitable for supporting each arm over at range of movement, said levers also each having an upper end portion, the upper end portions of the levers being connected to opposite ends of power cylinder means which, when being extended, pivots the levers to cause the arms to move together.
