Abstract: A knotter hook for a twine knotter has a stationary clamping wing and a pivotable clamping wing, Stationary clamping wing and pivotable clamping wing have an extension component in a same spatial direction. The pivotable clamping wing has a projection projecting toward the stationary clamping wing. The pivotable clamping wing is pivotable reversibly from a closed state into an open state. A free end of the pivotable clamping wing in the open state is spaced apart farther from the stationary clamping wing than in the closed state. The pivotable clamping wing is laterally displaced relative to the stationary clamping wing at least in sections so that the pivotable clamping wing is arranged adjacent to the stationary clamping wing and below the pivotable clamping wing a free space is formed. The free space extends in the closed state opposite to the spatial direction beyond the projection.

Abstract: In a method for operating a round baler, the harvested crop flow is controlled at any time of the bale forming process by time control with the control and governing device of the round baler, based on a stored theoretical minimum time for pressing a harvested crop bale defined by predetermined parameters and based on actually determined harvested crop parameters, such that the harvested crop bale defined by the predetermined parameters is produced at maximum baler utilization in a nominal press time determined for the harvested crop bale.

Abstract: An agricultural round baler has a press chamber with inlet and rear outlet for ejecting a bale. A pressing device in the press chamber causes the harvested crop to rotate. A pickup device and a conveying and cutting device are provided upstream of a storage chamber that extends to the inlet of the press chamber and receives harvested crop in a storage phase of the baler. An element that interrupts or releases flow of harvested crop from the storage chamber to the press chamber is provided and acted on by a control and governing device. The storage chamber is a flat shaping and pressing channel for the harvested crop conveyed in the storage phase of the baler operation. The channel has a height-adjustable end and a cross-section that at least temporarily in the storage phase tapers in flow direction of harvested crop to the press chamber.

Abstract: A baler is supported by wheels on the ground and is either self-propelled or hitched to and driven by a tractor. The baler has pickup and conveying devices for collecting and transporting the harvested goods to a pressing channel where bales are formed. The bales are tied by tying material supplied from a storage container arranged on the baler and moveable from an operating position into a servicing position allowing access to machine components of the baler covered by the storage container in the operating position. The storage container is moveable into a loading position for inserting or removing rolls of the tying material. The loading position and the servicing position are identical. In the loading and servicing position the storage container has, in comparison to the operating position, a greater spacing relative to a longitudinal center plane of the baler and a reduced spacing relative to the ground.

Abstract: A pull-type agricultural implement has a beam with drawbar hitch pivotable relative to the beam about a vertical axis and a horizontal axis extending in the travel direction. The drawbar hitch has a receptacle for a tractor drawbar. The receptacle enables pivoting of the drawbar about an axis that is horizontal and transverse to the travel direction relative to the drawbar hitch in a locked position. Guiding and adjusting plates in the receptacle allow adjustment of the receiving width of the receptacle to different drawbar dimensions. From a first position, in which the plates limit lateral play of a drawbar with large cross-section relative to the travel and working direction to a minimum, the guiding and adjusting plates are transferrable and lockable in a second position, in which the plates limit lateral play of a drawbar with small cross-section relative to the travel direction to a minimum.

Abstract: A baling press for producing large square high-density bales has a pick-up device picking up crop, a cutting device downstream of the pick-up device, a conveying device downstream of the cutting device, and a pressing channel disposed downstream of the conveying device and receiving the crop from the conveying device. The crop is shaped to high-density bales in the pressing channel. A tying device is provided that, for ensuring a permanent cohesion of the bales and completing the bales, ties tying medium strands, connected in endless loops, in longitudinal direction of the bales about the bales. A spacing of outermost tying medium strands, disposed next to outer parallel longitudinal bale edges, relative to the outer parallel longitudinal bale edges, respectively, is at least as large as or greater than an average spacing between neighboring tying medium strands in a transverse direction transverse to the longitudinal bale edges.
