With the newly designed tramline control, in total up to 2 x 5 seed rows can be switched off, so that the creation of any tramline gap is possible without a problem. The tramline control is made possible via a layshaft which drives the tramline seed wheels. If a tramline is being created, the layshaft is locked which then simultaneously stops the freely rotating tramline seed wheels on the seed shaft. The ability to cope with wider tramline gaps satisfies the use of husbandry tractors with tyre widths of up to 900 mm at 15 cm row spacing or 750 mm at a row spacing of 12.5 cm. Thanks to the two-piece spur gears, the track width and the tramline width can be matched quickly and without a problem.
