The invention relates to a cutting unit for mowing all types of clippings, the knife one executes translational circular movement.

So far, in mower cutting units of this type, fingers are on the front edge of the finger bar and placed counter-cut cutting blades arranged, making the construction cumbersome and becomes susceptible to failure. The protruding fingers may fold over the clippings and grasp them this is no longer the case, or they claw into the same or dig into thick-stalked clippings into it.

The purpose of the invention is to eliminate these disadvantages and to simplify and significantly Improvement of the known mower cutting units.

This is achieved in that in a mower of the type mentioned above, the knife a number of inclined cutting blades lined up on a knife back and in the direction of travel ahead of the front one, which carries a linear counter-cutting blade The front edge of a supporting beam, which is arranged in place of the usual finger beam, circles, with the back of the knife always remains parallel to the supporting beam.

This ensures that only one linear counter-cutting knife blade is the front edge of a instead of the finger bar, the support beam closes, with one over the front edge of the support beam, which is designed as a counter knife, is movably placed on the knife, which consists of a number consists of inclined cutting blades lined up next to each other on the back of a knife, is set in translatory circular motion. The counter-cutting knife blade is against the feed direction of the mower set at an angle.

According to the invention, the complicated protruding fingers and the applied counter-cut cutting blades are thus made by an elongated steel band, the side edges of which are made into knife edges are replaced.

In the drawing, an embodiment of the subject matter of the invention is shown schematically. It shows

F i g. 1 an embodiment of the cutting mechanism in plan view, - '·' F i g. 2 the same cutting unit in cross section.

In the drawing, cutting blades C are attached to a knife back E , which is moved in a translatory manner over a circle D , at an angle to it, which are attached to a cutting unit arranged parallel to the knife back for mowing all kinds of clippings

Neten, designed as a counter-knife, continuous support beam E close fitting in the direction of travel VR moving ahead and describe a scythe-like cutting path, pull the cut material to the front cutting edge of the support beam E designed as a counter-knife and cut it off like scissors.

The inclined leading cutting blades C arrive unhindered and immediately each clippings and separate thin and delicate as well as thick and strong stalks in a scythe cut scissors-like and saw-like without turning them over. Cuttings lying flat are also picked up and cut off if the cutting unit is set a little forwards and diagonally downwards.

Claims (1)

Claim: Cutting unit for mowing cuttings of all kinds, the knife of which executes a translatory circular movement, characterized in that the knife consists of a number of inclined cutting blades (C) lined up on a knife back (E) and reaching ahead in the direction of travel (VR) above the one linear counter- cut knife blade (A) bearing front edge of a support beam (B) arranged in place of the usual finger bar, the knife back always remains parallel to the support beam.
