Disc harrows with mounted seeder.
Disc harrows with built-on seeder form a unit for simultaneous skimming of stubble and sowing catch crops. The discs of the second group are covered with seeds sown directly after the stubble done by the discs of the first group.
The figure shows a connection diagram of the section of the two-track trailed disc harrow. The changed position of A is marked with dashed lines’ B’ C’ D’ And’ individual sections, obtained thanks to the longitudinal displacement of the AD slider rod in relation to the harrow frame. These shifts are made in steps, since the AD slider has spaced-apart locking notches. This way the angle of the discs is regulated, and therefore the intensity of soil mixing.
