Sumo’s new LDS subsoiler aims to minimise soil heave but can give different levels of surface soil disturbance according to the leg type specified.

It’s a 4m mounted machine with eight legs at 500mm spacing and will work from 100mm to 400mm depth. A 6m version is also in the pipeline. The idea is to perk up soil that has become compacted and it needs a tractor with at least 250hp under the bonnet.
