NRH Engineering has responded to demands for wider, folding versions of its Tremor subsoiler by delivering just that.

The new additions to the York-based maker’s fledgling range, first introduced at the Lamma show in January, are 4m, 5m and 6m wide and fold to a neat 2.8m for transport.

Like the rigid 3m, these carry a row of serrated 450mm straight discs ahead of the low-disturbance legs to slice through trash and discourage soil from bursting at the surface.

Consolidation is provided by either a toothed packer roller or the castellated rings and aggressive ribs of a pressed steel version.

Both have a 650mm diameter and hydraulic position adjustment – the latter a provision also afforded to the front discs.

Prices start at £15,000 for a 4m Tremor.
