Asystem developed by Lemken enables the companys range of Variowidth ploughs to work in both in-furrow and on-land ploughing settings. Available on five- to seven-furrow mounted and six- to nine-furrow semi-mounted models, the system is aimed at growers using both tracked and wheeled tractors. The "OF" link system is positioned between the ploughs mainframe and headstock, with a hydraulically cranked link providing the offset for in-furrow and on-land ploughing. The cranked link is also designed to ensure the ploughs overall length is not increased significantly when operating in the furrow. Available as a factory fit extra, the system is priced from £1350.
