Used Subsoilers For Sale in the UK

Subsoilers, as the name suggests work the soil under the surface, designed to open up the soil structure and improve drainage. The ideal subsoiler has minimum draft (meaning there is less pulling power required) but maximum heave to lift the soil as much as possible without unwanted clods coming to the surface. Most of the more modern subsoilers are designed in a V formation improving soil flow through the machine, this enables the legs to be closer together and improve lift across the width of the machine.

Are there safety mechanisms on Subsoilers?

Due to the working depth of the legs of a subsoiler, and therefore the strain, they have a safety mechanism to prevent damage to the leg. This can come in two types:

  • Shearbolt – a bolt with a specific breaking point is in the top of the leg when the leg snags on some hidden rock or object in the ground the bolt will break to save damage to the leg and frame.
  • Auto Reset – in particularly stony ground it may be better to use an auto-reset machine. These are normally protected by a hydraulic cylinder instead of a shearbolt, the cylinder is set to a specific pressure and like the shearbolt this trips when encountering something which applies more strain on the leg.  The benefit of auto-reset is that there is not part to replace after the leg has tripped.

What do Subsoilers do?

Some subsoilers are built for specific tasks i.e. grassland subsoilers. These have a leading disc in front of each leg to save the leg ripping up the grass roots. Another common sight is a subsoiler with a micro seeder mounted on the top. Often used for planting oilseed rape where the seed is dropped behind the leg. This gives the plant a deep fissure for the root to grow down. It is also common to have a subsoiler ‘tine bar’ which can be mounted in front of another cultivator of power harrow to enable two passes in one. 

What are Moledrainers and why are they important?

Included in our subsoiler category are mole drainers, these immensely popular machines are specifically designed to create a subsurface drainage channel. Thus improving the soil drainage and connecting land drains in the field. Mole ploughing generally has to be carried out after harvest and before drilling, in about a two-month window. The most important part of mole ploughing is ensuring that the soil is not too wet nor too dry. The soil needs to hold the shape that the mole has created, if it’s too wet it could fold in behind the mole and if it’s too dry it will crumble. Clay soils like those here at Gaydon Farm tend to be the one that needs the most help with drainage so benefit most from mole ploughing.

FAQ's about Subsoilers

To protect the legs of a cultivator or plough from damage, many machines will have shear bolts.  These bolts pass through the leg and frame of the machine and are designed to snap when the legs come in contact with a rock or other unmoving object.  The idea behind this is to save the frame and leg from bending, using an incorrect shear bolt and result in the bolt not shearing and expensive damage occurring to the machine.
