If required, the tractor wheel tracks can be loosened across a width of 3 or 4 m by using the SL wheel mark eradicators, which are mounted on an intermediate frame between the drill and tractor. The wheel mark eradicators loosen but do not mix. The soil-engaging parts are hydraulically swivelled up when turning on headlands. The SL 3000 can also be combined with a wide variety of seedbed preparation implements up to a support load of 4 t, such as when using a Catros compact disc harrow, for example.
