At Lamma earlier this year we launched our Stealth subsoiler. It came about through the close collaboration between HE-VA and OPICO and as a result of the demand for an ultra-low disturbance subsoiler from no-till and low till/min-till farmers and particularly where mixing soil horizons due to blackgrass is an issue.
Since its launch at LAMMA in January 20 the HE-VA Stealth has been busy demonstrating and has taken a number of orders ahead of late summer delivery. The HE-VA Stealth particularly complements the Sky EasyDrill – both in colour and system! The grey colour was a play on a “stealth” bomber and almost by accident aesthetically fits with the Sky colours. Future machines will be HE-VA red.
The HE-VA Stealth is a medium depth, low disturbance subsoiler. Its scalloped, straight, front cutting discs cut through the surface ahead of the low disturbance legs to minimise soil burst and in turn grassweed germination.
Legs are staggered in 2 rows to allow residue flow through the machine and reduces the required tractor lift capacity whilst maintaining a lower HP requirement. Leg spacing is standard at 500mm but can be altered to 450mm, 500mm or 550cm, adding versatility for differing soil types and conditions.
The hardened cast steel points are tungsten tipped and 120mm wide creating the necessary lift and shatter whilst ensuring longevity. Similarly, the 15mm ‘Hardox 500’ legs are thinner but stronger and more durable than standard subsoiler legs. A “V” profile roller re-consolidates and helps to retain moisture in the surface.
Surface compaction can be alleviated to a maximum working depth of 300mm (12”). HE-VA’s standard hydraulic depth control is fully adjustable from the tractor seat.
The Stealth has been designed to satisfy the requirements of no till and reduced input farming systems. However, it is also suitable for use in all farming systems where repair to damaged soil structure is required e.g. on headlands, tramlines or other trafficked areas.
