A connecting arrangement (1) for connecting a mower knife drive to a mower knife (7), that moves back and forth along a knife or X-axis, has a driving element (2) and an output element (3). The driving element (2) connects the connecting arrangement (1) to the mower knife drive. The output element (3) connects the connecting arrangement (1) to the mower knife (7). The driving element (2) and the output element (3) rotate relative to one another about three mutually perpendicular axes of rotation (X, Y, Z). Also, the driving element (2) and output element (3) can be moved relative to one another along at least two of the axes of rotation (Y, Z).

Decisive modifications are proposed to a cutting system reducing cutting losses and having a floating disk, in order to improve the efficiency of the system. The lower finger (1) cuts at the lower level and has a tip pointing upwards to prevent the finger from entering the ground; weeds passing past the lower finger pass over the upper finger (3), the accumulation of branches between the fingers being thus prevented. The upper finger (3) has a guard (4) that prevents grains from dropping out of the cutting platform, and the guard is also used to mount two bearings which act to orient the cutter bar (2).

The disclosure describes a cutting system for a harvesting header, which includes a transversely extending cutter bar, a transversely extending knife back, a knife section mounted to the knife back having a knife edge extending generally in a forward direction, a knife guard component having a front guard portion and a rear portion interconnected by a medial portion having a recess, the medial portion for receiving a lengthwise portion of the knife back with the knife section being received into, the knife section operable to move transversely into and out of a cutting slot in the front guard portion, a hold down component located between an upper surface of the rear portion of the knife guard component and an underneath surface of the cutter bar, and an attachment mechanism operable to secure the knife guard component and the hold down component to the underneath surface of the cutter bar.

A cutting system for a harvesting header includes a transversely extending cutter bar. First and second transversely extending knife backs are supported in relation to the cutter bar and are axially aligned with each other in a transverse direction. The first and second knife backs may each have a main body portion. At least one knife section is mounted to each of the first and second knife backs, each knife section having at least one knife edge extending generally in a forward direction. The first knife back is not attached to said second knife back. A crop divider structure is interconnected to the cutter bar and is operationally positioned between said first and second knife backs. The cutting system may also include first and second knife heads interconnected to the first and second knife backs and operable for interconnecting a knife drive system to drive the first and second knife backs.

In a cutter bar having a upper and lower knife guards in cooperating pairs mounted on a support bar where each guard includes at least one point extending forwardly to define a channel therebetween in which the knife reciprocates, the upper knife guards are attached to an upper surface of the support bar by a compressible resilient pad between an under surface of the upper knife guard and the upper surface of the support bar, at least one hold down screw fastener engaged between the upper knife guard and the support bar which holds the upper knife guard on to the resilient pad and forms a fulcrum and at least one adjustment screw between the upper knife guard and the support bar behind the screw fastener so that adjustment of the screw increases an amount of compression of the compressible resilient pad.

A header assembly for mounting upon a front end of a harvester combine's feeder house, the header assembly incorporating a central header which is adapted for fixed attachment to the feeder house front end; the header assembly further incorporating a lateral header and a pivot joint positioning an oppositely lateral end of the lateral header over the lateral end of the central header, the pivot joint being adapted for facilitating movements of the lateral header between a mowing position and a transport position, the lateral header cantilevering laterally over a crop edge upon pivoting to the mowing position and extending rearwardly upon counter-pivoting to the transport position.

An agricultural work machine is provided comprising a surroundings detection device for detecting a surroundings in sections, and one or more controllable working elements, wherein the surroundings detection device generates surroundings detection signals, which can be processed in a control and regulating device assigned to the agricultural work machine, wherein the surroundings detection device is designed as a scanner, which scans the surroundings in scanning planes, and wherein each scanning plane is assigned to the control of working elements.
