Last autumn we spent time turning over a range of soil types with a preproduction I-Plough in five-furrow form. That’s one option; the base unit can have four, five or six furrows and be pulled by tractors up to 280hp. The tractor itself need not be ISObus-equipped, as the company’s own IsoMatch Tellus Pro or Tellus Go displays are on hand for control. Breakback control can be by shear bolt — which explains the ‘B’ in the model name — or by leaf spring, the latter allowing auto-reset. The test plough arrived with number 28 boards, knock-on points, maize skimmers and disc coulters for the last body pair.
