Three-in-one cultivator goes under the radar

OPICO will launch a new version of its HE-VA Combi-Disc at the Cereals Event in June.

The ‘Stealth’ variant of the ever-popular combination cultivator gains ultra-low disturbance legs and a choice of different points depending on the level of sub-surface action required.

HE-VA Combi-Disc with Stealth low-disturbance leg and point

Now available in working widths from 2.45m to 5.25m 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.

It is this 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.

Likewise, with the legs lifted out of contention, the machine can be put to work as a straightforward shallow disc cultivator.

The addition of new ‘Stealth’ soil-loosening legs add further to the Combi-Disc’s versatility, making it a true low disturbance subsoiler with the added ability of being able 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.

“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 15mm wide Stealth low disturbance leg and low disturbance point are the product of many years of development. Whilst large numbers of growers are now moving towards reduced tillage systems they appreciate that drainage is key to crop development, allowing timely field operations and preventing the relentless progress of grass weeds such as blackgrass. The Stealth leg and point that HE-VA has developed 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. However, it is the point that really makes the difference. 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. 

Those wanting increased soil loosening across a wider profile can opt for a wider 200mm point. Both widths are available with and without long-life tungsten facing.
