A cutting device is embodied for cutting agricultural crop plants by a rotational movement about a cutting rotation axis and has at least one knife element that, in a plan view of a top side of the cutting device, is embodied open in circulating direction. At least one radial conveying element, arranged at least at the top side and stationary relative to the knife element, is provided that at least in sections thereof is embodied for conveying the crop plants in a conveying direction that, relative to the cutting rotation axis, is oriented partly tangentially and partly radially relative to the cutting rotation axis. Moreover, a harvesting attachment with a plurality of such cutting devices and a field chopper with such a harvesting attachment is provided.

An agriculture machine assembly working in combination with an agricultural work machine and a disk mower adapted to the agricultural work machine is disclosed. The agriculture machine assembly comprises a driver assistance system that optimizes operation and includes a computing unit and an operating and display unit. One or both of the agricultural work machine or the disk mower include at least one control device for controlling and regulating one or both of the agricultural work machine or the disk mower. The driver assistance system is structured such that it forms a work machine setting device and a disk mower setting device, which optimize the operation of the agricultural work machine and the disk mower depending on each other.

Uneven distribution of grass clippings in a grass clippings receptacle of a lawn mower can be minimized. A lawn mower includes: a work unit including a housing having a downward-facing opening and a cutter blade rotatably provided in the housing such that the cutter blade cuts grass and generates a transport air flow flowing from the opening of the housing to inside; a grass clippings receptacle configured to receive mowed grass clippings; a grass clippings transport passage connecting an interior of the housing with the grass clippings receptacle; a shutter device including a shutter configured to open and close the grass clippings transport passage and an actuator configured to open/close-drive the shutter; a controller configured to control the shutter device; and a speed sensor for detecting a travel speed of the lawn mower, wherein the controller is configured to open/close-control the shutter device based on the travel speed.

A crop harvesting blade is provided for use in a mechanical crop harvesting machine to improve ratooning e.g. a chopper harvester for harvesting sugar cane. The crop harvesting blade has a plurality of rectangular teeth located at and uniformly arranged along the entire periphery of the blade body. The blade also has an attachment arrangement configured to provide a plurality of attachment positions for releasable attachment of the blade body to a base plate of a cutting portion of a mechanical crop harvesting machine. Upon attachment of the blade body to the base plate in each attachment position, the corresponding portion of the plurality of teeth is placed in an operative position.
