Abstract: Animal training apparatus particularly useful in the training of cutting horses to cut a cow or calf from a herd. The apparatus includes a pneumatic tube, preferably annular, mounted at a selected height above the ground by support members. The tube is provided internally with a piston which is reciprocally moveable at a desired speed and direction by compressed air fed into and removed from air ports in the tube by an air compressor. A wheeled carriage, mounted on the exterior surface of the tube, carries a second magnet, magnetically coupled to the first magnet of the piston, for movement of the carriage in concert with the piston. An artificial cow or calf downwardly depends from the carriage, serving as a stimulus for training of the horse.
