Cereals 2023 will see Opico launch the newest version of its HE-VA Combi-Disc.
The ‘Stealth’ variant has ultra-low disturbance legs and a choice of different points depending on the level of sub-surface action required.
Working widths from 2.45m to 5.25m are now available in both mounted and trailed formats. The Combi-Disc employs two leading rows of soil-loosening legs followed by two rows of serrated Sabre discs to provide a surface chopping and mixing effect. This is all followed up with a V-profile roller to produce a corrugated, weather-proof finish.
Opico report that the combination of soil-engaging elements that makes the Combi-Disc such an adaptable tool. In normal circumstances the tines, discs and press are used in partnership to turn previously uncultivated ground into a seedbed in one pass. When conditions require it, the discs can be lifted completely out of work, enabling the unit to be used as a straightforward subsoil loosener/pan-buster.
Opico’s HE-VA product manager, Glenn Bootman, said: “With the increased focus on regenerative practices, we’re seeing a need for cultivation kit that can reduce soil disturbance but still deal with compacted layers in the soil profile to ensure decent drainage and rooting to maximise crop potential.
“With this new leg option for the Combi-Disc we are answering that requirement. The basic principle is medium-depth, low disturbance soil loosening combined with shallow surface cultivation. I believe that now makes the Combi-Disc one of the most adaptable tillage tools on the market.”
The Stealth leg and point allows deep soil loosening whilst minimising surface disturbance and preventing mixing of the soil profile. The narrower legs are made from ultra-strong Hardox steel and can be interchanged with standard 25mm wide subsoiler legs as necessary. The Stealth standard 120mm low disturbance point has a shallower wing angle and shorter nose that has been designed to open up the soil to create drainage fissuring without mixing the whole soil profile.
