Stealth LD Subsoiler

The HE-VA Stealth – 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. 

The Stealth is available as a 3m, 3.5m, 4m, 5m and 6m mounted or 5m, 6m and 7m trailed machine. Machines over 3.5m fold hydraulically.

A Stealth kit i.e. legs and points are available to retro fit to existing HE-VA machines e.g. the HE-VA Subsoiler range and for all

The 15mm low disturbance leg and tungsten tipped LD point are also the product of many years development. Whilst many customers are 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 low disturbance leg and point that HE-VA has developed allows deep soil loosening whilst minimising surface disturbance and preventing mixing of the soil profile.

The thinner legs are made from stronger Hardox 500 steel. However, it is the point that really makes the difference. The Stealth point has a shallower wing angle and shorter tungsten tipped nose that opens the soil to create drainage without disturbing the whole soil profile.

The Stealth legs and points can be interchanged with the standard subsoiler as necessary.
