FIELD: agriculture.
SUBSTANCE: invention refers to the field of agricultural machine building, namely to cutting structural elements of soil-cultivating machines. A chisel comprises a plate with a sharpened edge and a hole for fixation to a ploughshare. The plate is made of two parts connected to each other with a welded seam. The first part of the plate represents a connection element with holes. The second part of the plate is a cutting-blade part from steel with higher hardness. A coating of a wear-resistant alloy is applied onto the surface of the cutting blade part.
EFFECT: proposed structural design makes it possible to increase chisel service life and to improve its repairability.
