The Onyx subsoiler for working depths of up to 60 cm, completes the Lemken range of tillage implements. Designed to withstand tough conditions, the Onyx is available in two rigid versions: the Onyx MR/300 with a 3.0 meter working width and the Onyx MR/400 with a 4.0 meter working width.
This subsoiler features a simple and robust design. The frame structure is not assembled, but welded together to ensure stability and durability. A notable feature is the 90 cm underframe clearance, which provides ample space to the base frame even at the maximum working depth. The frame also features a clear design with two beams spaced 84 cm apart, ensuring easy access for inspection and maintenance.
Centerpiece of the Onyx is its share system, which comes in two variants with a 42.5 cm line spacing. It can be used with the OM (Onyx Mixing share) or the OL (Onyx Loosening share). Both shares are hard-faced as standard and optionally available with carbide coating to withstand wear-intensive operating conditions.
The OM share, which is designed to move and intensively mix the soil, is mounted on a curved stalk with a guide plate. With a working depth of 25 to 40 cm, it is ideal for improving the soil structure through medium-depth loosening and subsequent levelling. Thanks to the hydraulic depth adjustment, the Onyx can be operated directly from the tractor, making it suitable for variable operating conditions.
The OL share, on the other hand, is mounted on a straight stalk and is designed for deep loosening at working depths between 40 and 60 cm. It lifts the soil, creating cracks due to the lifting action and the weight of the soil itself. This breaks up compacted layers such as plough pans and improves water infiltration through the resulting micro-cracks.
Both share variants can also be equipped with wings. These ensure a wider and more homogeneous loosening of the soil, as well as a better mixing in of organic matter.
For levelling and reconsolidation of the loosened soil, two rollers are recommended, specially adapted to the Onyx: the DSW 580 double spiked roller and the RSW 600 tube bar roller. A quick-change roller system enables the rollers to be changed quickly, providing maximum flexibility in variable soil conditions.
The Onyx will be available in limited numbers from 2026.
