Maschinenfabrik Bernard Krone GmbH & Co. KG

A round baler has a rear door pivotable relative to the frame. A circulating press element defines a press chamber inside the frame for forming crop bales. A tension rocker is pivotable relative to the frame and has a rotatable rocker guide roller guiding the press element. A first pressure element is arranged at frame and rear door and acts between frame and rear door. A second pressure element is arranged at rear door and tension rocker and acts between rear door and tension rocker. At least one of the pressure elements is a linear actor. By length expansion of the first pressure element, rear door and tension rocker are pivotable, wherein the rear door is pivotable upwardly to enable ejection of crop bales. The rear door is pivotable downwardly by length expansion of the second pressure element. A method for operating the round baler is provided.

A conveyor for a baler has a feed bar with first and second bar parts connected by a coupling such that, from a stop position, the bar parts are rotatable relative to each other in a rotational direction against a restoring force and coupled to each other in the stop position to prevent rotation in opposite rotational direction. The conveyor conveys crop within a collection chamber toward a press chamber in collection mode and from the collection chamber into the press chamber in feed mode by feed tines of the first bar part. The conveyor guides the first bar part in collection mode by a feed collection lever of the second bar part and by force transmission via the coupling and guides the first bar part in feed mode partially by a feed lever of the first bar part by rotating the bar parts relative to each other.

A haymaking machine has a rake rotor with frame and support arm provided with a base part and a sliding part. The base part is pivotably connected to the frame about a support arm axis to enable the support arm to pivot between a lowered active position and a raised passive position. The sliding part is slidable relative to the base part between an inner position and an outer position for length adjustment of the support arm. The outer position is farther removed from the support arm axis than the inner position. A catching element is connected to the sliding part. A linear drive is connected to frame and sliding part to move the sliding part into the inner position and pivot the support arm from active position into passive position. A retaining mechanism holds the support arm in active position until the sliding part has reached the inner position.

A round baler has a feed channel, a bale chamber, and a starter roll. The starter roll is arranged at an inlet side of the bale chamber and driveable about an axial roll axis in rotational direction. The starter roll feeds a crop flow from the feed channel to the bale chamber for bale formation. A catch device is provided for catching falling material. A tangentially extending catching chamber is formed between the catch device and the starter roll. The starter roll engages material in the catching chamber and feeds the material back to the crop flow. The catch device has a deflector element that, in a rest position, delimits the catching chamber at least in sections radially outwardly. The deflector element is elastically deflectable at least radially outwardly from the rest position such that an exit opening for the material from the catching chamber is produced or expanded.

A cutting device is embodied for cutting agricultural crop plants by a rotational movement about a cutting rotation axis and has at least one knife element that, in a plan view of a top side of the cutting device, is embodied open in circulating direction. At least one radial conveying element, arranged at least at the top side and stationary relative to the knife element, is provided that at least in sections thereof is embodied for conveying the crop plants in a conveying direction that, relative to the cutting rotation axis, is oriented partly tangentially and partly radially relative to the cutting rotation axis. Moreover, a harvesting attachment with a plurality of such cutting devices and a field chopper with such a harvesting attachment is provided.

A method for field processing includes mowing, via a mowing machine having at least one mower, a crop within a processing area so as to provide a mown crop. At least one mowing parameter is determined for each position of a plurality of positions within the processing area. The at least one mowing parameter has a mower parameter which relates to the at least one mower and which is associated with an area density of the crop. The mown crop is processed via a cropmaking machine which has at least one processing device. At least one cropmaking parameter which characterizes an operation of the cropmaking machine is set as a function of a position of the cropmaking machine. The at least one mowing parameter is determined for the position

A binding needle for a needle yoke of a bale press. The binding needle includes a mounting element which mounts to a rocker support of the needle yoke, a guide element which at least indirectly guides a strand-shaped binder, and a needle body which is made of a metal. The needle body is at least partially formed by a pipe profile which defines a profile interior. The needle body is arranged to extend from the mounting element to the guide element and to run at least in sections in a manner of an arc along a plane of curvature so as to define an inside of the arc and an outside of the arc.

A tool for mounting a chopping knife to a chopping drum. The tool includes a clamping mechanism for releasably fixing the tool in an auxiliary bore of the chopping drum, a frame, an adjusting element, and a positioning element. The clamping mechanism is reversibly adjustable from a basic state, in which the clamping mechanism is unclamped, to a clamping state, in which the clamping mechanism is clamped. The adjusting element is reversibly displaceable relative to the clamping mechanism and/or the frame in a displacement direction along a displacement axis. The adjusting element reversibly adjusts the clamping mechanism from the basic state to the tensioned state. The positioning device positions the chopping knife on the chopping drum.

A haymaking machine for tedding or raking agricultural stalk or leaf material includes a tedding or raking rotor arranged on a machine beam. The tedding or raking rotor is rotated about a vertical axis when working/operating. The tedding or raking rotor includes two tine arms aligned approximately radially which are uniformly distributed in a circumferential direction about the vertical axis, a first spring tine having a first length arranged on the two tine arms, a second spring tine having a second length arranged on the at least two tine arms, a first measuring device which interacts with the first spring tine, and a second measuring device which interacts with the second spring tine. The second length is smaller than the first length. The first measuring device measures a force acting on the first spring tine. The second measuring device measures a force acting on the second spring tine.

A method for a route planning for a field processing. The method includes passing an agricultural machine through a primary area of a processing area while automatically determining position data thereof, at least partially automatically determining a primary boundary which surrounds the primary area based on the position data, determining a secondary outer boundary of a secondary area, the secondary outer boundary being arranged outside the primary area to meet the primary boundary at connection points, automatically determining a driving route for processing at least the secondary area, and automatically generating control data for controlling the agricultural machine during the field processing. A part of the primary boundary which lies between the two connection points forms an inner boundary between the primary area and the secondary area. The inner boundary, together with the secondary outer boundary, completely surrounds the secondary area. The control data represents a determined driving route.
