  • Patent number: 11446972
    Abstract: Agricultural implement having a tow bar device for towing the implement with a towing vehicle includes an implement part that trails the tow bar device mounted so as to be pivotable about a first pivot axis. The first pivot axis is parallel to a horizontal transverse axis of the implement. The trailing implement part and the tow bar device are coupled by means of at least one first actuator. The tow bar device, by means of the first actuator, is pivotable about the first pivot axis in such a manner that a tilt angle between the tow bar device and the trailing implement part is adjustable.

  • Patent number: 11058063
    Abstract: An implement includes a bale cutting device, which includes a carrier that can be pivoted about a pivot axis, and a support connected to the carrier. A cutter bar is attached to and supported by the support so as to be movable at least substantially in the direction of a longitudinal extent of the support. The implement may include at least one pick-up for engaging a bale. In operation, the cutter bar is positioned on a far side of the bale, with the bale between the carrier and the cutter bar. The cutter bar may then be drawn inward into the bale to cut the bale approximately in half.

  • Patent number: 10982693
    Abstract: An automatically actuated shunt valve system opens and closes a passage between two chambers of a powered element operated by a power source. The shunt valve system includes a coupler connecting the powered element with the power source through two mating coupling elements. One of the coupling elements includes a valve contact and the other includes a shunt valve assembly. The shunt valve assembly includes a valve chamber connected with both chambers of the powered element, a valve element opening or closing a flow path between the conduits, and a shaft for moving the valve element. The shaft engages the valve contact to move the valve element to close the flow path when the coupling elements are mated together, and moves the valve element to open the flow path when the shaft disengages from the valve contact as the coupling elements are disconnected from one another.
