Abstract: An agricultural vehicle comprises separate wheel suspension assemblies corresponding to each wheel of the vehicle. Each wheel suspension assembly includes a strut assembly wherein the strut assembly is connected to the chassis at a pivot and to a respective wheel, and a dual action hydraulic cylinder that is connected to both the strut assembly at a point distal from the pivot and the chassis of the vehicle. Motion of the strut assembly around the pivot is affected by action of the hydraulic cylinder. In some embodiments, the dual action hydraulic cylinders are in fluid communication with the diagonally opposite hydraulic cylinder such that when one cylinder moves into an extended or retracted position the other diagonally opposite cylinder is urged into the same position. In some embodiments, the wheel suspension assemblies are attached to slidable drawer assemblies on each side of the vehicle.

Abstract: A chassis suspension for agricultural equipment, the chassis suspension comprising: an axle having a substantially upright journal adapted for upright axial constraint of an inner journal therein; an inner journal extending into the upright journal, the inner journal having a lower end, wherein the inner journal is adapted to constrain axial movement of a strut rod therein; a strut rod extending into the inner journal and having a lower strut rod portion adapted for mounting a ground-engaging drive mechanism and wheel, wherein the lower strut rod portion has an upper end; and, a spring constrained between the lower end of the inner journal and the upper end of the lower strut rod portion.

Abstract: A method and apparatus for treating bagged materials. A bagging machine is equipped with feed tubes that feed a conduit through a bag filling tunnel of the machine and through the open end of the bag and into the bag. The conduit is perforated and when the bag is filled, the length of the conduits is extended out through the bag end to be connected to a treatment media, e.g., forced air. An opening is provided at the rear end to provide an exhaust opening for air that is forced into the conduit, out the perforations and through the bagged material. The air will dry the material to lower the moisture content or provide oxygen as may be desired to enhance decomposition. Water may also be introduced as desired.

Abstract: A rotor for a bagging machine used to force feed material, e.g., silage, for compaction in a tunnel of the machine prior to insertion of the material into a large storage bag. The rotor includes teeth sets closely spaced along the length of the rotor and each teeth set including at least three circumferentially spaced teeth. Preferably the teeth of each teeth set are intregal with a support or base ring that slidably fits en elongate pipe or tube and position axially in circumferentially as desired and then weld tacked to the pipe.

Abstract: A rotary rake is provided with a hydraulic lifting mechanism for raising and lowering the rake. A vertical shaft extending through the center of a rotary gearbox on the rake serves as a hydraulic fluid port. Pressurized hydraulic fluid from a remote source passes through the shaft to a hydraulic cylinder mounted on a support frame. The hydraulic cylinder operates a mechanical linkage which raises and lowers the rake. The mechanical linkage includes an over-center position for securely holding the rake in the raised position.
