Buyers of He-Va’s Combi-Disc cultivator now have the option of 15mm-wide, ultra-low disturbance Stealth legs as an alternative to the standard 25mm fitment.

To further reduce soil movement and minimise the risk of dredging up viable weed seeds, they can be paired with 120mm points, with a shallower wing and shorter nose than usual.

These will work to a maximum depth of 400mm to alleviate compaction, create drainage fissures and encourage quick rooting of the following crop.

Behind the two rows of legs come another two 510mm serrated discs, typically set to work at 125mm to chop and mix trash and topsoil.

Hydraulic control of these elements means their depth can be adjusted on the move, and either can be lifted out of play to form a conventional subsoiler or a shallow disc cultivator.

At the back, there’s a single or twin V-profile roller to leave a weatherproof finish.
