  • Patent number: 4640662
    Abstract: A fork lift attachment for a tractor. The fork lift attachment includes a subframe having a pair of arms that are attached to the sides of the tractor. A mast is pivoted to the outer end of the subframe and is adapted to be pivoted in a fore and aft direction by a hydraulic cylinder unit. Mounted for movement on the mast is a fork rack and a sliding rack, which carries the lift forks, is mounted for lateral movement on the fork rack. A pair of lift cylinders are mounted along the sides of the mast and operate to move the fork rack and lift forks relative to the mast, while a shift cylinder interconnects the fork rack and the sliding rack to shift the sliding rack and forks in a lateral direction. The lift cylinders are spaced apart to provide an opening for the power take-off of the tractor so that the fork lift attachment does not interfere with normal operation of the power take-off or the three-point hitch system.
