  • Patent number: 12103827
    Abstract: A clamp assembly comprising a pair of clamps may couple to an assembly body. The clamps may pivot to receive material beneath the assembly body. The clamps may include opposing surfaces that define a scoop space beneath the assembly body. Each of the clamps may include a cutting plate. The cutting plate may include a perforating edge configured to extend into the scoop space relative to a corresponding one of the opposing surfaces. The clamp may further include a retention plate. The retention plate may include an inner surface that faces the cutting plate. The cutting plate and the retention plate further define the scoop space between the clamps. The clamp assembly may couple to a lift assembly. The lift assembly may include a hydraulic actuator configured to raise and lower the clamp assembly.

  • Patent number: 10518920
    Abstract: Systems and methods for towing a bagging machine are disclosed. The system includes a coupler connected to a hopper that is configured to raise and lower relative to a chassis of the bagging machine. The chassis has at least six wheels in contact with the ground that remain in contact with the ground when the coupler is attached to a towing vehicle hitch. The hopper raises to attach the coupler to the hitch and lowers to engage the hitch for towing, while keeping the wheels on the ground.

  • Publication number: 20140137520
    Abstract: A bagging machine having a uniquely configured rotor that can be operated with a grill, enables removal or injection of fluid materials when filling a bag. In one mode, the rotor enables the removal or draining of an effluent created from the bagging process such as from silage. In another mode, the rotor enables the injection of a treatment agent such as an antifungal agent as material is bagged.
