A cutting edge for agricultural use provides opposed cutting edges arranged to be rotationally symmetric about an axis so that the cutting edge may be reversed in the field to repair or replace the cutting edge without the need for separate spare parts. In some embodiments a support plate may provide a ledge stop supporting the unused cutting edge to absorb impact shocks without cutting edge damage.

A control system for mixing materials for livestock feed including a container that receives the materials, agitators that mix the materials in the container, a driveline that drives the agitators at an output speed with an output torque, a power source that provides an input speed at an input torque, a continuously variable transmission that connects the driveline and the power source and having a hydrostatic loop to provide a speed ratio between the input speed and the output speed, a plurality of sensors positioned between the power source and the agitators that provides mixing signals commensurate to mixing parameters, and an electronic control unit configured to receive the mixing signals, extract mixing parameter values from the mixing signals, and actuate the continuously variable transmission and adjust the speed ratio based on the mixing parameter values to enhance efficiency of the mixing of the materials.

A system is described comprising a mixer-wagon and a mechanical power transmission unit to actuate the rotating members of the mixer-wagon; the transmission unit comprises a box, a first shaft accessible from the outside of the box and a second shaft accessible from the outside of the box. The first shaft and the second shaft are coupled by means of an epicyclical gear train.

An agricultural vehicle including a container, which is mounted on at least one train of wheels, wherein the container rests by way of fixation brackets and load cells or weight sensors, preferably directly, i.e. without use of an intermediate chassis, on one axle or more forming the train of wheels. The vehicle container is mounted on the axle or each of the axles of the train under consideration by way of at least two pairs of load cells, wherein each pair consists of two load cells situated on opposite sides of a vertical plane parallel to the vertical planes containing the axes of the axles of a multi-axle train.

Fodder mixing wagon with a mixing container and at least one mixing member arranged rotatable therein for fodder components and a sensor system arranged to co-rotate on the mixing member for examining at least one of the fodder components and/or a fodder mixture formed therefrom. A data transmission system with a transmitter a receiver which are associated with one another in a co-rotating and not co-rotating arrangement for wireless data transmission to and/or from the sensor system; and/or an electrical generator for supplying power to the sensor system. The transmitter and receiver are arranged such that the wireless data transmission is within the mixing container; and the generator is arranged on the stator side to co-rotate with the mixing member and on the rotor side is coupled not to co-rotate. Data transmission is provided with a low transmission power. Inductive data and power transmission may be used.

An agricultural machine for transportation and distribution of bulk products, including a tank, which is mounted on a rolling chassis, which is provided with at least one sealable opening situated at the level of the bottom of the tank and which is equipped with at least one mobile device performing scraping of the bottom and favoring ejection of the product. An agricultural machine wherein the mobile device or each mobile device is mounted to rotate around a vertical shaft or axis, perpendicular relative to the plane of the bottom and including at least two separate radial arms, distributed around the axis and sweeping over substantially the entire surface of the bottom, wherein the thickness or the height of each arm relative to the bottom is smaller than the height of the lateral opening or of each lateral opening.

A feed-mixing device for receiving, mixing and dispensing animal feed includes a frame with a mixing bin for receiving and mixing the animal feed therein and dispensing it therefrom, at least one mixing device rotatably drivable in the mixing bin using a drive, in particular a vertical mixing auger, for mixing the received animal feed, and a weighing device for determining the weight of the animal feed received in the mixing bin, comprising N weighing elements, with N?2, each of which emits a weighing signal, and a control system for controlling the feed-mixing device and for processing the weighing signals from the weighing elements to produce the determined weight. The control system is configured to perform an, in particular fully automatic, calibration action of the weighing elements. The calibration action includes driving the at least one mixing device, reading out the respective weighing signal of each of the N weighing elements in each of M different positions of the mixing device, with M?N, calibrating the weighing elements on the basis of the read-out weighing signals, wherein the calibrating at least includes determining a respective correction factor for the weighing signal of each weighing element by analysing the read-out weighing signals of all weighing elements. Thus, all weighing elements may be calibrated without having to detach the weighing elements, which provides very reliable weight measurements in a very simple manner.

A livestock feeding system with a feed preparation area containing at least one storage, a livestock stable which is connected via driving routes to the feed preparation area, and a robot which comprises a variable speed electric drive controllable by a frequency transformer and a battery, and which is optionally connectable to a power supply at least in the feed preparation area, is a power rail line in the feed preparation area routed past the storages and a docking device to the power rail line. The robot contains a high-voltage DC battery which is connected to an intermediate circuit of the frequency transformer.
