Knight’s new Raven cultivator, orginally designed by Cambridgeshire farmer Steve Raven, is available with a 2.8m working width.

A 3.5m version is planned for next year. Three subsoiler tines with reversible legs work at depths of up to 35cm (14in) and lift the soil for a set of Knight’s Empress tines complete with knock-on points to work on. Two rows of discs, which can be lifted clear if the implement is to be worked just as a subsoiler, are followed by a press which also controls overall working depth. An oilseed rape seeder unit is available as an option.
