LUR disc for disc harrows

LUR discs have been devised to carry out tillage aggressively and energetically to shred and mix even the most resistant waste with disc harrows. They penetrate more deeply into dry soils than into normal soils, a working depth ranging from 15 to 25 cm being considered advisable. However, they are also highly effective at a shallower depth when ploughing and tilling in wet soils.

It is advisable to assemble these disc harrows helicoidally in each socket (as the hole is square, it is simply a question of turning one position with respect to the preceding disc) in order to put the rotation of the assembly to best use, to work at a greater speed than usual and to till well.
