Abstract

Machine for seeding designed to be pulled by a tractor and outfitted with seed drills for depositing of the seeds in the soil. A furrow opener is mounted forward of the seed drill, and a furrow closer is mounted aft of the seed drill. The furrow closer is mounted on the frame for pivoting in a vertically extending plane behind the seed drill, and comprises a support pivotally mounted on the frame and a hiller mounted on the support by a mounting device for projection of the hiller below the mounting device and into the soil for closing of the furrow. The mounting device is secured to the support by a releasable fastener so that length of the projection of the hiller below the mounting device can be adjusted.
