Abstract: A rotor apparatus for feeding granular or powdered material in an agricultural implement, the rotor apparatus being designed to be received in a partially cylindrical feeder space of a feeder device for volumetric feeding. The rotor apparatus comprises an insert part, which in size and shape is adapted to be inserted into the feeder space and to substantially prevent air from passing the insert part when this is inserted into the feeder space, and a rotor, which is rotatable relative to the insert part. The insert part defines a rotor space, in which the rotor is rotatable, and the rotor is together with the insert part designed to provide an air lock. The insert part comprises a wall portion interacting with the rotor and located radially outside the radially outermost portion of the rotor.

Abstract: This document sets out a method of adjusting an agricultural implement's orientation. The method comprises recording, while the agricultural implement is travelling, a series of orientation values corresponding to the orientation of the agricultural implement in at least one vertical plane, calculating a derived orientation value based on said series of values and, if the derived orientation value is outside a predetermined range, adjusting a mutual position relationship between at least two parts of the agricultural implement that can move relative to each other.

Abstract: The document discloses a disc tool (1) for breaking up field residues, comprising a central hub portion (10), which is designed for mounting the disc in a tool holder in order to make the disc rotatable about a rotation axis (Ar), a cultivating portion (11), which is located radially outside of and adjoins the hub portion (10), and a plurality of substantially straight cutting edges (E1, E2) which are located at the periphery of the disc tool. The cultivating portion (11) has a plurality of undulations (111, 112) which, with an axial extent decreasing toward the inside, run from the cutting edges (E1, E2) to the hub portion (10). The cutting edge (LE1, E2) is designed such that 90-98% of a track formed by the cutting edge consists of straight track portions. The document further discloses an agricultural implement with such disc tools, the use of such an agricultural implement, and a method for manufacturing such a disc tool.

Abstract: An agricultural implement comprising a first frame section, a portion which is moveable relative to the first frame section, and an actuator for controlling a relative movement between the first frame section and the portion. The agricultural implement has a first sensor arranged to provide a first value corresponding to the angle of the first frame section relative to a predetermined reference plane or a predetermined reference direction, and a second sensor arranged to provide a second value corresponding to the angle of the portion relative to the predetermined reference plane or the predetermined reference direction. The reference plane or reference direction is defined in relation to a direction of gravity.

Abstract: The present document discloses a rotor apparatus (20) for feeding granular or powdered material in an agricultural implement, the rotor apparatus being designed to be received in a partially cylindrical feeder space of a feeder device for volumetric feeding. The rotor apparatus (20) comprises an insert part (21), which in size and shape is adapted to be inserted into the feeder space and to substantially prevent air from passing the insert part when this is inserted into the feeder space, and a rotor (22), which is rotatable relative to the insert part. The insert part (21) defines a rotor space (218), in which the rotor (22) is rotatable, and the rotor is together with the insert part designed to provide an air lock. The insert part (21) comprises a wall portion (214, 215) interacting with the rotor and located radially outside the radially outermost portion of the rotor.

Abstract: The present document discloses a meter housing for feeding granular or powdered material. The meter housing comprises a meter space with a material inlet and a material outlet, and a wall portion extending between the material inlet and the material outlet. The wall portion has substantially the form of a cylinder sector. The wall portion has a scraper part, which extends substantially parallel to a central axis of the cylinder sector.

Abstract: A method and a system in an agricultural machine for the coordination of agricultural machines when refilling substance intended to be disseminated over an agricultural field by generating coordination data indicative of an optimum refill location, comprising a level sensor arranged for generating level data, said level data indicating a volume of a substance in a substance reservoir; a position sensor for generating and storing position data and storing or reading a preplanned route; a communication device arranged for transmitting and receiving data; characterized by: a coordination device generating coordination data, based on said level data, said preplanned route and said position data; and transmitting said generated coordination data via the communication device to a refill vehicle.

Abstract: A sealing gasket made of a resilient rubber material or rubber-like material. The sealing gasket is formed as a rotationally symmetric body with a substantially constant cross-sectional profile. The cross-sectional profile includes: a first sealing part located furthest away from a center of rotation of the body and a second sealing part located radially inside the first sealing part, as viewed in the radial direction. An open space is defined by the first and second sealing parts. The second sealing part essentially curves through an angle away from the center of rotation. A seed housing can include such a seal and a seeder can include such a seed housing.

Abstract: A device for feeding granular material, such as seed, fertilizer or pesticide is described herein. The device includes at least two metering devices (109), a first drive device (101) for generating a pressurizing airflow (FT) for pressurization of the metering devices (109), and a central container (102), which is arranged to, via respective feed ducts (103), with the aid of a respective feed airflow (FI), feed the material to the respective metering device (109). The device also includes a second drive device (201, 201a, 201b) for generating the feed airflow (FI) and a merging connection (118, 118?) for merging at least a part (FL) of the feed airflow (FI) with the pressurizing airflow (FT).
