Subsoiler

Introduction

Introduction

HEVA Subsoilers are designed for minimum draft and maximum heave without bringing large unwanted clods to the surface. 

They come in 6 frame sizes 3m, 3.5m & 4m rigid and 4m, 5m & 6m hydraulic folding with a number of different leg options to create the correct specification to do the best job on any individual farm.

There are models to suit most farms and tractors sizes up to 600hp.

Features

Shearbolt Subsoiler

Shearbolt SubsoilerThe Subsoiler “Hammer Thru” quick change shear bolt system protects the machine in tough, stony conditions and means minimum  down time for the operator. Its “tolerance style” shearbolt allows several resets before the need for a change.

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

Hydraulic Reset Subsoiler

Hydraulic Reset Subsoiler

All Subsoiler models are available with hydraulic auto reset for extremely stony conditions. An individual hydraulic ram 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 an unmovable object. 

As the legs on a Subsoiler are adjusted 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 Leg & Point Design

The V formation layout of the frame, angle and design of the 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. Hardox points are available in narrower versions at 80mm and 120mm widths and wider versions at 300mm and 350mm to suit different applications.

 

Bolt on points using a single bolt are quickly replaced keeping down time to a minimum.
   
The 200mm cast steel point allows approximately 30% longer life than Hardox steel points.
Subsoiler Depth Control

Susoiler depth controlThe HE-VA Subsoiler hydraulic depth control is a useful feature making it easy for the operator to alter the working depth – for example to work the Subsoiler deeper up the tramlines or in habitually water logged areas. 

It also simplifies hitching and unhitching the Subsoiler from the tractor.

Rear Rollers

V-Profile Roller

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.

V-Profile Roller

Synchro Roller

The HE-VA Synchro Roller is designed to improve germination and therefore establishment of Till-Seeded crops of oilseed rape. In damp conditions with friable soil germination is not a problem, however in dry Autumns where seedbeds are invariably not as kind, good consolidation is critical.

Syncro Roller

In order to germinate seeds need moisture, in the absence of actual rainfall then dew and soil moisture are the only sources. In order to ensure that this moisture reaches the seed “Soil to Seed Contact” needs to be achieved. When soil particles are pressed together and into contact with the seed this allows capillary action to take place to move the moisture in the soil. The seed will naturally absorb moisture and swell so the moisture needs to be able to move towards the seed through consolidated soil. The areas inbetween Till-Seeded oilseed rape rows do not need to hold moisture and in fact are better off not being consolidated so that they do not promote weed and volunteer growth.

The design of the Synchro Roller utilises all these facts, the Synchro roller presses the band of soil where the seed has been planted with a rubber tyre packer but the space in between is hardly touched. The T profile rings in between the rubber tyres are of a slightly smaller diameter so they only come into work when there are large clods sitting on the surface or the field is uneven. These T profile rings do however keep clean in the wet and prevent soil building up on the roller. The tyres are also designed to flex and keep clean so that they can work in the wet.

When using the Synchro Roller on a Subsoiler for drilling oilseed rape the weight of the whole machine and down draft from the legs is effectively applied to 40% of the working width. This more than doubles the pressure used for consolidation in the seeded area and dramatically enhances the soil to seed contact as a result. This extra consolidation means it is less critical to roll after Till-seeding the rape although it is still recommended.

Low Disturbance Leg & Point Option

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 and can be interchanged with the standard subsoiler legs as necessary. However, it is the point that really makes the difference. The 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.

Models

Rigid Subsoilers

For use with low to higher horsepower tractors, on medium to large sized farms, the Rigid Subsoiler from HE-VA is designed to tackle the toughest challenge.

With 3, 5 and 7 leg Subsoiler models available, offering 2.5m, 3m, 3.5m and 4m working widths respectively, these machines combine outstanding performance to deliver substantial productivity benefits.

Rigid Subsoiler

Folding Subsoilers

For use with high horsepower tractors on larger farms, the hydraulic folding Subsoiler from HE-VA is designed to tackle the toughest challenge.

With 7 and 9 leg Subsoiler models available, offering 4 metre and 5 metre working widths respectively, these machines combine outstanding performance and mobility to deliver substantial productivity benefits.

Each of the Subsoiler models splits and folds down to a width of 2.43 metres for easy transport and access. Full lighting kits are available as an option.
