Abstract: A hitch that connects to a chassis of the work vehicle and rotates with respect to the chassis includes a first bracket connected to a first portion of the chassis, a first stabilizer bar connected to the first bracket, and a first hitch arm connected to the first stabilizer bar. The first hitch arm has a free end that engages a work implement. A second bracket is connected to a second portion of the chassis. The second portion of the chassis is spaced from the first portion of the chassis, so that the second bracket is spaced apart from and independent of the first bracket. A second stabilizer bar is connected to the second bracket. A second hitch arm is connected to the first stabilizer bar. The second hitch has a free end configured to selectively engage the work implement.

Abstract: An apparatus is for a bulldozer crawler tractor. The apparatus includes a mounting assembly configured to fixedly attach to the bulldozer crawler tractor. A ripper assembly is configured to be operatively attached to the mounting assembly. A winch assembly is configured to be operatively mounted to the ripper assembly.

Abstract: A folding implement frame having seven sections in a use position and nine sections when folded. The frame design allows a frame having a width of greater than 27 meters to be folded into a transport position having a width of less than eight meters and a height of less than six meters. The hydraulic system transfers weight to the center frame section during folding and unfolding to enhance stability. The hydraulic system uses accumulators to minimize the amount of oil reduction in the tractor reservoir resulting from extension of the hydraulic cylinders of the implement. Implement raise and lower cycle times are minimized by a helper cylinder to lift the frame main section when the entire implement weight is on the main section and allowing a smaller cylinder to lift the frame main section in the use position for shorter cycle times to raise and lower the implement.

Abstract: An agricultural implement includes a forward implement frame and an aft carrier frame with wheels, with the two frames pivotally connected. The implement frame includes a hitch mechanism for attaching the implement to a traction vehicle, while a toolbar having a plurality of working units, such as ground working tools or spraying units, arranged in a spaced manner along its length is attached to an aft portion of the implement frame. Attached to the carrier frame is a storage container for dispensing material such as fertilizer or a herbicide. A forward portion of the carrier frame is pivotally coupled to an intermediate portion of the implement frame. A lift arrangement including a pair of hydraulic cylinders connecting the implement and carrier frames is located aft of the pivot connection between these two frames and permits the toolbar and working units to be raised to a nonuse position such as for transport or at the end of a field without lifting the storage container and its contents.

Abstract: This invention relates to a dirt leveling device adapted for towing by a tractor which is characterized by one or more chisels attached to a transverse shaft on the front of the dirt leveling device having a rotatable relationship thereto, and a dirt leveling blade rotatably attached to the frame and controlled by a second hydraulically actuated ylinder. The hydraulically actuated cylinder for the chisels and the hydraulically actuated cylinder for the blade may be controlled by extensions to the vicinity of the driver of the towing vehicle.

Abstract: The invention is directed to a foldable agricultural implement frame having a first pair of controlling/controlled lifting hydraulic cylinders for lifting and lowering the right wing section and the center section together in a level condition, and a second pair of controlling/controlled lifting hydraulic cylinders for lifting and lowering the left wing section and the center section together in a level condition. In the first pair of controlling/controlled hydraulic cylinders one of the hydraulic cylinders lifts the right wing section and the other lifts the center section. In the second pair of controlling/controlled hydraulic cylinders one of the hydraulic cylinders lifts the left wing section and the other lifts the center section. A rephasing valve assembly is used to rephase the controlling/controlled hydraulic cylinder pairs when the implement frame is folded and only the center section needs to be lifted and lowered.

Abstract: An apparatus for forming cross country ski tracks in a snow covered surface has a trailer frame adapted to be connected to the rear end of a vehicle. A lifting frame is connected to the trailer frame for pivotal movement about a first horizontal axis. The lifting frame has a pair of parallel guide members extending longitudinally from the trailer frame to a transversally extending crossbar. The guide members are arranged symmetrically on opposite sides of a central axis common to the lifting frame, the trailer frame, and the vehicle. At least one cross country ski track forming device is connected to the crossbar for pivotal movement about a second horizontal axis. A positioning device is connected between the trailer frame and the lifting frame.
