摘要

Behind a on the coulter holder of a sowing coulter by means of a resiliently elastic arm, which has at least one spring turn, arranged seed contact pressure roller, wherein the resilient arm is fastened at one of the coulter holder and, on the direction of travel, a projecting toward the rear retaining element, which the resiliently elastic arm by means of a fork-like guide element laterally on both sides of the leads, is arranged. Around a better lateral guidance of the seed contact pressure roller, while maintaining the feather possibility of the seed contact pressure roller, because of the spring coil to maintain in the upright direction, it is provided that the retaining element with the guide element in the region of the spring coil of the resiliently elastic arm is arranged.
