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.

An improved cutter assembly for use with a header of an agricultural harvester is provided. The assembly includes a pair of oppositely directed knife blades or cutter bars and a center knife drive. A crank shaft drives both knife blades in linear reciprocating paths with no fore and aft movement. As a consequence, harmful fore and aft vibration is eliminated. The assembly is simple and durable in design, less susceptible to vibration-induced wear and tear, and comparatively simple to manufacture and repair.

The present invention provides a switchable cutting blade paired with a harvester knife guard. The switchable cutting blade comprises a switchable cutting blade assembly in which a knife guard is not included and which is provided with notches, so that waste blockage can be cleaned automatically. The switchable cutting blade assembly comprises a cutting bucket steel plate and a plurality of cutting blade bottom frames which is arranged on the cutting bucket steel plate and is closely connected. Each cutting blade bottom frame comprises a triangular part A and a groove frame which is integrated with the triangular part A. Each of the groove frames and the corresponding cutting blade bottom frame form an ┘ shape; each two adjacent cutting blade bottom frames are fixed by a crossbar to form a new knife guard. Each cutting blade bottom frame is provided with a cutting blade component. Each cutting blade component comprises a blade part and a mounting part arranged at the rear end of the blade part. Each mounting part comprises a groove which is fixed on the corresponding groove frame. The switchable cutting blade disclosed by the present invention has the main advantages that a mounting face C and the corresponding cutting blade bottom frame can be fixed at the cutting bucket steel plate together by screws. A new knife guard can also be directly welded on the cutting bucket steel plate.
