Abstract: A cargo trailer for towing behind another vehicle has a cargo container platform and a stabilized caster swivel assembly supporting the cargo container platform. The swivel assembly includes an elongated frame, a caster wheel on a swivel member being rotatably mounted about a vertical axis to a rear end of the frame, a cam member mounted on the swivel member for rotation therewith, a centering mechanism coupled to the cam member, a hydraulic stabilizing mechanism coupled to the swivel member, and a hydraulic control circuit mounted on the frame.

Abstract: An apparatus for retrieving and carrying large cylindrical objects and adapted to be secured behind a towing vehicle, the apparatus comprising an A-frame having a wheel supported cradle assembly pivotally secured to one end thereof, a pivotal bail member provided on the cradle assembly, the cradle assembly being movable to a first position for an initial engagement with the lower portion of the cylindrical object and to a second position whereby gravity acts on the bail member for moving the bail into engagement with the outer periphery of the object and a third position for elevating the object into a carrying position whereby the object may be transported from site to site by the apparatus, and the movement of the cradle assembly being reversed for discharging the object from the apparatus.

Abstract: Tucker wheelers for use on a hay baler in which hay is picked up from a window in the field, the tucker wheels being mounted on each side of the hay baler, the planes of the wheels being at an acute angle to the longitudinal axis of the hay baler. Each of the tucker wheels comprises a rotating wheel carrying radial wire spokes extending outwardly from the circumference, the spokes being attached to springs so that they can deflect through a wide angle. Each wheel is mounted at an elevation so that the spokes will engage the earth, and the wheel will rotate as the vehicle moves, picking up hay from the outer edges of the window and moving it towards the center of the windrow. Each wheel is attached to the baler with a universal joint mount allowing for use on uneven ground and allowing the wheel to caster when the hay baler is backed up.
