ABSTRACT:
A loader attachment includes a frame with a pair of arms pivotally connected thereto and depending therefrom. A tine is pivotally mounted at the lower end of each arm, and projects forwardly from each arm. Hydraulic cylinders are mounted between the frame and the arms to selectively pivot the arms inwardly towards one another and outwardly away from one another. A parallelogram linkage is provided on each arm to maintain the orientation of the tine on the arm as each arm is pivoted. A drive linkage interconnects the two parallelogram linkages such that the tines maintain an orientation relative to one another as the arms are pivoted. A hydraulic cylinder is connected between the frame and the drive linkage to permit selective rotation of the tines in opposing directions on the lower ends of the arms.
