These studies lead to the realization of a very strong, reliable machine that allows the preparation of the seeding- bed through one only passage. The MAGHIRUS rotary harrow is fitted with a gearbox central PTO, disposes of a wide range of gears allowing several rotation speeds to the rotors to be coupled to tractors with a power takeoff from 540 r.p.m. to 1000 r.p.m. The round tineholders made in forged steel are fitted with blade tines remarkably strong, with a special tooth contour requiring a very low energy input. The MAGHIRUS rotary harrow can be equipped with several components that make it a complete machine able to fulfill every working needs.
