Improve soil health by Stealth
Amongst grassland and livestock farmers there is a growing demand for effective, low disturbance subsoiling to loosen and fracture the medium depth subsoil to relieve compaction, caused by poaching and vehicle damage, thus assisting drainage and water infiltration, aeration, nitrogen uptake and encouraging grass rooting.

Working closely with HE-VA, OPICO has taken the need for a low disturbance subsoiler and customer feedback onboard and together designed a totally new low disturbance subsoiler specifically for the UK market.
With HE-VA having over 15 years of expertise in producing subsoilers coupled with the past five years of manufacturing low disturbance subsoiling machines, the HE-VA Stealth – a medium depth, low disturbance grassland subsoiler was developed.
The Stealth's low disturbance legs are staggered in 2 rows to allow residue flow through the machine to reduce 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 550mm, adding versatility for differing soil types and conditions.
The 15mm hardened cast steel low disturbance points are tungsten tipped and 120mm wide creating the necessary lift and shatter whilst ensuring longevity. Similarly, the 15mm leg is thinner than a standard subsoiler leg but, being made from “Hardox” gives it strength and durability.
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 was originally designed to satisfy the requirements of no till and reduced input farming systems, however, there are several benefits to using the Stealth on grassland - to alleviate compaction from livestock and machinery, improve air interchange and drainage whilst minimising surface damage.
The Stealth is available as a 3m and 3.5m, rigid, linkage mounted machine or 4m, 5m and 6m hydraulic folding, linkage mounted or trailed machine.
FEATURES & BENEFITS
Stealth 15mm LD Legs & Points
The Stealth 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 Stealth 15mm low disturbance leg and point that HE-VA has developed allows sub-soil conditioning whilst minimising surface disturbance and preventing mixing of the soil profile.
The thinner legs are made from stronger Hardox steel. However, it is the point that really makes the difference. The Stealth point has a shallower wing angle and tungsten tipped nose that opens the soil to create drainage without disturbing the whole soil profile.
V-Profile Rear Rollers
Like many of the machines in the HE-VA range the Subsoiler uses the pressed steel V-Profile ring as standard. However, all the rings are mounted on a 300mm tube so that each section of the roller turns as one ensuring the machine can continue to work in very wet sticky conditions.
Each ring section is castellated ensuring the roller turns in light soils and the aggressive rib and shoulder profile combines with the 125mm spacing to leave an excellent consolidated weatherproof finish.
Front Cutting Discs
Scalloped, straight front cutting discs cut through the surface ahead of low disturbance legs to minimise soil burst and damage to the productive sward.
Shearbolt Leg Protection
The Subsoiler “Hammer Thru” quick change shearbolt system protects the machine in tough, stony conditions and means minimum down time for the operator. Its “toblerone style” shearbolt allows several resets before the need for a change.
When the legs brake back the operator simply removes the holding pin and hammers another segment of the shearbolt through then returns the holding pin to its original position. This removes the need to carry a supply of shearbolts while using the Stealth low disturbance subsoiler.
Alternatively there is a Hydraulic Reset Subsoiler version for extremely stony conditions.
Hydraulic Auto Rest Leg Protection
All models are available with hydraulic auto reset for extremely stony conditions. An individual hydraulic cylinder on each leg which is connected to a gas accumulator allows the leg to break back and reset if it comes into contact with an unmovable object.
As the legs on a Stealth low disturbance subsoiler are adjusted deeper the leverage on the hydraulic reset cylinder increases and so a pressure gauge is used to allow the operator to set the force required for the leg to break back.
DEPTH CONTROL
Hydraulic Depth Control
The HE-VA Stealth grassland low-disturbance subsoiler's hydraulic depth control is a useful feature making it easy for the operator to alter the working depth – for example to work the machine deeper, for example in habitually water logged areas.
It also simplifies hitching and unhitching the Stealth subsoiler from the tractor.
Disc Depth Marker
Depth markers are fitted to all new Stealth subsoilers to show the position for the front leading disc as standard. There will be a single marker fitted to in the right hand side of all width machines.
