Suitable for small to medium tractors, in-furrow ploughs make ploughing easier. The tractor wheels sit in the furrow for good grip and traction, especially in wet conditions. The furrow guides the tractor which is especially useful if you do not have GPS guidance. On-land ploughs are suitable for high power tractors, including tracked, twin wheels or wheels over 710 mm in width. By working on-land, tyre wear is reduced, especially on flinty soils. The Gregoire Besson semi-mounted on-land ploughs allow you to work either in-furrow or on-land.
