Abstract
A soil working tool for an agricultural machine includes a carrier that comprises a cutting region having a cutting edge, and one or more hard-material elements being arranged in the cutting region. The hard-material element is a cutting element that forms at least a part of the cutting edge.
Claims29
A soil working tool for an agricultural machine, comprising:
- a carrier including a cutting region, the carrier including a front side facing in an advance direction and a rear side facing oppositely from the front side, the cutting region of the carrier including an end face separating the front side of the carrier from the rear side of the carrier,
- one or more hard-material elements arranged in the cutting region, the hard material element being harder than the carrier, wherein the hard-material element is an L-shape cutting element having a cross section defined in an L-shape having a longer leg and a shorter leg, the longer leg defining mounting piece extending over and bonded by material attachment to the front side of the carrier and including a flat front facing defection surface, and the shorter leg defining an extension formed on the mounting piece and protruding away from the front side of the carrier;
- wherein the extension of the cutting element is includes a support surface supported by and bonded by material attachment to the end face of the carrier, and the extension includes an exposed surface extending at an acute angle to the flat front facing deflection surface of the mounting piece;
- and
- wherein the cutting element includes a cutting edge joining the front facing deflection surface of the mounting piece and the exposed surface of the extension.

A soil working tool for an agricultural machine, comprising:
- a carrier including:
- a front side;
- a rear side;
- an end face separating the front side from the rear side;
- a recess formed in the front side adjacent the end face, the recess including a front facing surface;
- one or more mounting receptacles defined through the carrier from the front side to the rear side for mounting the carrier to the agricultural machine;
- and
- at least one L-shape cutting element formed of a hard material harder than the carrier, the L-shape cutting element having a cross section defined in an L-shape having a longer leg and a shorter leg, the L-shape cutting element including:
- a mounting piece received in the recess and defining the longer leg of the L-shape, the mounting piece including a rear facing surface engaging and bonded to the front facing surface of the recess of the carrier, and the mounting piece including a flat front facing deflection surface;
- and
- an extension defining the shorter leg of the L-shape, the extension extending rearward from the mounting piece, the extension including a support surface supported by and bonded to the end face of the carrier, and the extension including an exposed surface extending at an acute angle to the flat front facing deflection surface of the mounting piece;
- and
- a cutting edge defined on the cutting element and joining the front facing deflection surface of the mounting piece and the exposed surface of the extension.
