A chisel sowing coulter, for direct and/or mulch sowing, includes: a coulter body, a tear-open chisel fastened by a fastening device, and coulter blades laterally projecting from the tear-open chisel and provided with a front cutting edge, which are arranged in order to create a sowing furrow in the ground. In order to change the penetration depth of the sowing coulter into the ground, the coulter blades are adjustable about a horizontal axis that extends transversely to the direction of travel, and that is fixable in different positions by way of an adjustment device arranged between the tear-open chisel and the coulter body.
