Abstract

A blade for a furrow cutter has a planar fastening region which is located in a fastening plane. The blade is driven in rotation via a transmission arranged in a transmission housing. The fastening plans separates a first region of the furrow cutter from a second region of the furrow cutter. The transmission is arranged in the first region. The blade has at least one arm projecting from the fastening region and having a free end. The arm has a first segment which extends out of the fastening plane into the second region. A simple structure, a good cutting result and a high service life are achieved when the arm has a second segment in which the arm extends back in the direction of the fastening plane.
