SUBSOILER

Shearbolt

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 - no spanners required!

Alternatively there is a Hydraulic Reset subsoiler version for extremely stony conditions.

Hydraulic Reset Subsoiler

All subsoiler models are available with hydraulic auto-reset for extremely stony conditions. An individual hydraulic cylinder on each of the subsoiler legs which is connected to a gas accumulator allows the leg to break-back and reset if it comes into contact with a large stone/unmovable object. It also means less downtime.

As the legs on a subsoiler are adjusted to work deeper, the leverage on the hydraulic reset ram increases and so a pressure gauge is used to allow the operator to set the force required for the leg to break back.

Subsoiler 25mm Leg & Point Design

The V formation layout of the frame, angle and design of the standard 25mm legs ensure that HE-VA Subsoilers have a relatively low draft requirement. The points are also designed to lift and heave without huge HP requirement. A variety of points are available.

The standard long life cast point has a 200mm wide wing. Other narrower versions are available at 80mm and 120mm widths and wider versions at 350mm to suit different applications.

200mm tungsten tipped points are available as an option.

Bolt on points using a single bolt are quickly replaced keeping down time to a minimum.

The 200mm cast steel point with tungsten tip allows approximately 30% longer life than a Hardox steel point.

Stealth 15mm LD Leg & Point Option

The Stealth 15mm LD (low disturbance) leg and tungsten tipped LD point are 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 steel and can be interchanged with the standard 25mm subsoiler legs as necessary. However, it is the point that really makes the difference. The Stealth 120mm LD point has a shallower wing angle and shorter tungsten tipped nose that opens the soil to create drainage without disturbing the whole soil profile.

Stealth 15mm low disturbance legs can be retro-fitted to any HE-VA subsoilers.

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. Mounted machines are fitted with a 600mm diameter roller, whilst the trailed machines are fitted with a 700mm diameter roller. HE-VA's uniquely designed scrapers ensure 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 effectively breaks down clods leaving an excellent, consolidated weatherproof finish.

Front Cutting Disc Option

Add front cutting discs to your subsoiler to help cut through trash, minimise surface disturbance and reduce soil burst. These are particularly effective with Stealth legs and points seen in the image above.
