Abstract: A method for determining setting recommendations for an agricultural spreader includes the steps of: determining an uneven spreading-material distribution in a usable agricultural area or an uneven nutritional status of plants in the usable agricultural area, determining an ideal balancing distribution of spreading material that balances out unevenness of the determined spreading-material distribution in the usable agricultural area or unevenness of the determined nutritional status of the plants in the usable agricultural area, and determining setting recommendations for the agricultural spreader for implementing a balancing distribution of the spreading material, wherein the balancing distribution approximates the ideal balancing distribution.

Abstract: A method for planning spreading of a spreading material mixture with an agricultural spreading machine includes steps of: identifying individual components of the spreading material mixture, determining component-related setting parameters for the agricultural spreading machine for a planned spreading operation for several or all of the individual components of the spreading material mixture, and evaluating joint spreadability of the individual components of the spreading material mixture on the basis of the determined component-related setting parameters by a calculating device.

Abstract: An electronic machine management system for initiating switching and actuating procedures with positional accuracy in agricultural working machines, has a geographic module for determining a current position, and based on information regarding positions of critical field data, quantities to be applied, field boundaries, work areas and/or areas to be avoided, and a machine-specific module that contains machine-specific functionalities, the modules being configured so that the geographic modules supplying the machine-specific module with geographic information in real time, and, based on the geographic information in real time, the machine-specific module generating machine-specific switching and actuating procedures in real time and sending signals relevant thereto to particular switching and actuating elements.

Abstract: A seed drill for applying seed and/or fertilizer has a frame, reservoir, and sowing shares. The sowing shares are attached to the frame in such a way that they can move in an upright plane by means of superimposed and at least approximately parallel struts on parallelogram mounts. To essentially improve the share mounts, allowing them to be employed on direct-sowing seed drills and especially on soils thickly set with entrenched stones or other obstacles and preventing damage to the shares or share mounts when the shares are laterally overstressed, at least one strut on a parallelogram mount is elastic.

Abstract: A throughput-adjustable fluid-displacement machine includes a stator and a rotor which is supported on the stator for rotation about an axis. The stator has two axially spaced circumferentially extending cam tracks and the rotor has two sets of passages therein, each of the passages having an open end which always faces a different one of the cam tracks for each of the sets of passages. A plurality of pistons is respectively accommodated in the above-mentioned passages, each of the pistons having a cam follower portion and being acted on by a spring which urges the cam follower portion into a constant contact with the respective cam track so that the piston reciprocates in dependence on the configuration of the respective cam track. Two control sleeves, one for each of the sets of passages, is interposed between and selectively communicates the working chambers of the respective passages with respective input and output conduits of the machine.
