Bout markers

Tractor with precision seeder with the bout markers folded out on both sides.

Bout markers (also known as bout markers ) are additional mechanical assemblies on agricultural implements (especially seed drills ), which are used to leave a driving mark for the subsequent journey when working the field. This means that straight rows can be driven in parallel with no gap or overlap.

Use and meaning

Bout marker that leaves a clearly visible mark.

Tracks that are cleanly driven in parallel and lying next to each other have various advantages. Overlapping of the tracks is minimized, which avoids double processing and saves seeds.

While track markers are usually attached to a device on both sides, when driving in the field, usually only the track marker on the unprocessed side of the field is unfolded. In this way, the track is drawn for the next drive across the field.

In some cases, the track markers are set in such a way that one of the tractor tires can be driven in the marked track during the subsequent journey. Longer track markers can also be set to the middle of the following track, which has the advantage that the distance between the marked track is independent of the width or the wheelbase of the tractor used.

Bout markers are often moved hydraulically . The track markers are often folded over automatically when the seed drill is raised, so that the track marker is active again on the unprocessed side after turning.

Bout markers are becoming less and less important as digital , mostly GPS- based parallel driving systems are being used more and more in automated agriculture .
