SOWING COULTER, IN PARTICULAR CHISEL COULTER

摘要

The invention relates to a sowing coulter, in particular a chisel coulter (7), preferably for the direct and/or mulch sowing method, comprising a coulter body (23), in the lower front region of which and at the front side of which coulter body (23), a tear-open chisel (17), which is fastened by means of a fastening device (24), and coulter blades (26) laterally projecting from the tear-open chisel (17) and provided with a front cutting edge (25), are arranged in order to create a sowing furrow in the ground. In order to create a simplified fastening of the coulter blades (26), and at the same time an improved adjustment of the tear-open chisel (17) having the coulter blades (26) with respect to the coulter body (23) by changing the penetration depth of the sowing coulter (7) into the ground such that an optimized adjustment and orientation of the coulter blades (26) to the ground at any penetration depth of the sowing coulter (7) in the ground is maintained, according to the invention, the coulter blades (26) are arranged on the tear-open chisel (17), the tear-open chisel (17) having the coulter blades (26) is adjustable about a horizontal axis (27) that extends transversely to the direction of travel, and that is fixable in different positions by way of an adjustment device (28) arranged between the tear-open chisel (17) and the coulter body (23).
