Abstract: A rotatable pick-up device, which is installed or installable in an agricultural harvesting machine, for harvested crop, having a roller-shaped drum with an outer lateral surface that has an outside diameter, a multiplicity of tine rings that are arranged on the outer lateral surface of the drum and protrude over the outside diameter of the drum, intermediate spaces for receiving strippers provided between adjacent tine rings, and the tine rings have tine segments that, in the mounted state, are arranged entirely above the lateral surface and are manufactured from an elastic plastic. The tine rings and the tine segments have mutually complementary fastening means, by means of which the tine segments can be mounted on the tine ring without the tine ring being removed.

Abstract: A cutting blade overload protection device for a cutting mechanism of a harvester for leaf and stalk material, having a cutting blade pivotable about a cutting blade rotational axis and which is connected to a toggle lever mechanism. The toggle lever mechanism includes two coupled toggle levers pivotable about a toggle lever rotational axis and which move the cutting blade from an operating position to a resting position when a predefined force is exceeded. To protect the cutting blade better when contacting foreign objects, the device has a toggle lever mechanism which comprises a stop limit and a spring element, with the spring element and limit stop interacting such that when a predefined force is exceeded, the toggle lever rotational axis is moved past a dead center point, with the position of the toggle levers shifting from a first buckling position through a straight position into a second buckling position.

Abstract: A method for autonomously controlling a feed mixing vehicle, a vehicle having an autonomous controller, a computer program for carrying out the method, and a control device. The vehicle has a chassis, working elements for carrying out partial tasks, scanners/sensors for transmitting data, and a computer for controlling all the processes. The scanners/sensors acquire spatial data of the surroundings and generate therefrom a 3D map of the current geometry of the surroundings. The current geometry of the surroundings is placed in relationship with an area that is released to be traveled on by the autonomous vehicle, with the result that the navigability of the travel path of the autonomous vehicle is checked, and in the case of detected non-navigability the travel path is adapted autonomously to the requirements of the situational spatial surroundings and is replaced by an alternative travel path.

Abstract: The invention relates to a cutting blade overload protection device (10) for a cutting mechanism (11) of a harvester (100) for leaf and stalk material, comprising at least one cutting blade (13) which can pivot about a cutting blade rotational axis (12) and which is connected to a toggle lever mechanism (14). The toggle lever mechanism (14) includes two coupled toggle levers (16, 17) which can pivot about a toggle lever rotational axis (15) and which move the cutting blade (13) from an operating position (P1) to a resting position (P2) when a predefined force (F1) is exceeded. The invention also relates to a harvester (100) which is equipped with at least one such cutting blade overload protection device (10).
