Designed to work at depths of up to 60cm, the Onyx subsoiler is available in two rigid widths of 3.0m and 4.0m.
The welded frame provides 90cm of clearance and the 84cm spacing of the two beams is said to provide good access for maintenance. Two shares are available: the OM (Onyx Mixing) or the OL (Onyx Loosening). Both are hard-faced as standard and are optionally available with carbide coating.
Mounted on a curved leg with a guide plate, the OM is designed to move and intensively mix the soil to depths of 25 to 40cm. Mounted on a straight leg, the OL lifts the soil to break up compacted layers at working depths from 40 to 60cm. Both shares can also be equipped with wings to increase soil loosening and mixing of organic matter.
There are two specially adapted rollers: the DSW 580 double spiked roller and the RSW 600 tube bar roller. A quick-change system allows them to be swapped to suit the conditions.
Depth adjustment is hydraulic and the Onyx, which completes Lemken’s range of tillage implements, will be available in limited numbers from 2026.
