Opico will launch a new version of the He-Va Combi-Disc at the Cereals Event. It has Stealth ultra-low disturbance legs and a choice of different points depending on the level of sub-surface action required.
The 15mm wide Stealth legs are made from Hardox steel and carry a 120mm low-disturbance point. This has a shallow wing-angle and short nose and has been designed to open up the soil to create drainage fissuring without mixing the whole soil profile.
For increased soil loosening a wider 200mm point can be fitted. Both widths are available with and without long-life, tungsten facing. The narrow legs can be interchanged with standard 25mm wide subsoiler legs as necessary.
Now available in working widths from 2.45m to 5.25m in both mounted and trailed formats, the Combi-Disc has two leading rows of soil-loosening legs followed by two rows of serrated Sabre discs for chopping and mixing. Finally a V-profile roller produces a corrugated, weather-proof finish.
In normal circumstances the tines, discs and press are used together to turn previously uncultivated ground into a seedbed in one pass. If required, the discs can be lifted out of work, enabling the unit to be used as a straightforward subsoil loosener/pan-buster.
Likewise, with the legs lifted out of contention, the machine becomes a straightforward shallow disc cultivator.
The addition of the new soil-loosening legs changes the Combi-Disc into a low-disturbance subsoiler with the ability to provide some surface tilth creation at the same time.
“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,” explains Opico’s He-Va product manager Glenn Bootman.
