At least one profile portion (10) is divided into an inner contact portion (12) as well as an adjoining outer edge portion (13). The body halves (9) are at least partially connected by means of a substance-to-substance bond (15) radially on the inner side of the contact portion (12).

Abstract: The present invention relates to a method for determining a turning radius of a trailer attached to a towing vehicle and moved by the latter, comprising a computing unit, which is connected to a measuring sensor system, which transmits sensor data about current movements of the trailer to the computing unit, and which sensor data is considered by the computing unit for the determination of the turning radius. The invention also relates to a trailer, which is equipped with a device, which uses a method of this type.

Abstract: A metering device for an agricultural machine for outputting granular solids from at least one storage container to at least one dispensing unit by means of a conveyor system has a metering housing, and at least one inflow opening and at least one discharge opening for the granular solid. The metering housing forms a metering chamber on the inside. Between the metering chamber and the conveyor system a conveyor device rotating about a rotary axis is arranged. The conveyor device comprises at least one first rotary slide valve with at least one first opening for controlling the inflow and/or discharge of the granular solid into the or out of the conveyor device.

Abstract: A roller for agricultural soil cultivation has at least one support body rotatably mounted about an axis of rotation and multiple compaction rings arranged spaced apart from one another next to one another on the support body and intermediate rings arranged between adjacent compaction rings. At least two intermediate rings have a different diameter and/or a different width.

Abstract: A metering device for an agricultural machine for outputting granular solids out of at least one storage container to at least one dispensing unit by means of, in particular, a pneumatic conveyor system, has a metering housing. The metering housing comprises at least one mounting flange on the storage container-side and/or conveyor system-side as well as at least one inflow opening and at least one discharge opening for the granular solid. The at least one mounting flange is formed as polygon or circular.

Abstract: A seed drill having a frame, to which at least one seeding coulter and a fertiliser coulter arranged upstream of the seeding coulter in a working direction are connected. The seeding coulter and the fertiliser coulter are each assigned depth control.

Abstract: A method for planning the cultivation of an at least quadrangular area of an agricultural field is presented. The area has edge sections between its corners, including a first edge section and a second edge section. The second edge section is arranged opposite of and oblique to the first edge section. A plurality of first working paths and a plurality of second working paths are determined. A lane that runs at least partially along the first working paths and the second working paths and along which an agricultural machine is to be moved over the area is determined. A plurality of turning points along the lane at which the machine is steered is determined, such that the lane runs less along the first working paths and further along the second working paths as the distance from the first edge section increases.

Abstract: A hydraulically-foldable agricultural machine frame includes a hydraulic cylinder assembly that connects and pivots two lateral parts of the hydraulically-foldable agricultural machine frame relative to one another, wherein unrestricted pivoting or folding of the lateral parts is prevented by movement of the hydraulic cylinder assembly only being guided or delimited laterally.

Abstract: The invention relates to a soil-working device having an overload protection means, in the case of which overload protection means rebound energy is reduced after the soil-working device returns from an overload position to the working position.

Abstract: The invention relates to a hose connector system (1) for use in an agricultural spreader machine (15), which system is characterized by rapid and secure assembly, and therefore economical production and high modularity.

Abstract: A semi-mounted plough has a rear chassis, the plough trailing behind a plough-towing tractor in a laterally pivotable or steerable manner by a vertically oriented joint. In order to compensate lateral pulling for the tractor, which is generated by the traction force of the plough about the vertical axis of the tractor, an energy accumulator is arranged, which generates a torque counteracting the lateral pulling.

Abstract: A press wheel comprises an outer, circular tyre element, for an agricultural sowing machine, wherein ribs enclosed by an elastic filler material ensure improved radial and lateral guidance and suspension for the press wheel.

Abstract: An agricultural seed drill with a seed sensor, generally of the type having a plurality of row units comprising a separation device. The separation device is provided with two or more separate outlet openings for separated seeds, and wherein each outlet opening is associated with a guide channel and a furrow opener, for depositing seed into a ground furrow. Further, a detector is arranged between the outlet opening and the furrow opener, to detect the discharge of a separated seed element through the outlet opening into the furrow opener and to convert it into a signal.

Abstract: The invention relates to a soil-working device having an overload protection means, in the case of which overload protection means rebound energy is reduced after the soil-working device returns from an overload position to the working position.

Abstract: A ground working implement comprises a frame for receiving working tools and a trailer tower on one side of the ground working implement for attaching the ground working implement to a vehicle. An auxiliary chassis arranged on an other side of the ground working implement with at least one wheel arm and a wheel rotatably fastened thereto. The at least one wheel arm is movable vertically with respect to the ground working implement via at least one linkage. At least one energy accumulator is arranged movably between the frame and the at least one wheel arm with at least one bearing, wherein the at least one bearing is arranged on a straight line. The at least one linkage is arranged in a lowered position and a raised position of the at least one wheel arm along the straight line.

Abstract: A towed soil cultivation implement (1) is proposed in which the soil tillage tools (5) are guided by a contact pressure controlled depth guide device (9), which enables a constant weight load on a downstream, adjustable reconsolidation implement (6) on uneven ground as well. In the process, the pull line between tractor (3) and soil cultivation implement (1) are maintained in an optimum position.

Abstract: Viewed in the direction of travel, fertilizer coulters and swivel-mounted seed coulters (13) are arranged at coulter arms (40) on the frame (6) of a pneumatic precision seed drill. Between them there is a working device designed as a roller (15), which is designed for the re-compaction of the soil thrown up by the fertilizer coulter (12), the pre-compaction of soil between the working device (14) and seed coulter (13), and as a depth guidance roller for the precision seed drill.

Abstract: A soil tiling apparatus (1) having a combing or leveling device (4) mounted in front thereof, wherein, when the tool intensity of the combing or leveling device (4) is adjusted, at the same time in the driving direction a change in the distance between the tool supports to each other or to the trailing soil tilling tools (3) is brought about in a simple manner.
