Inversa IG

IG stone burier, specifically designed to bury rocks, clods, and residues in the most efficient way. It allows to bring back to the surface the lightest part of the soil allowing for an easier sowing. Unique with its central gear box of solid gears. Made with high tensile steel, it is available in 2.5 and 3 meter working width. Maximum hp allowed: 170 hp


Rotor with 6 helicoidally positioned blades

The reverse rotation of the rotor, combined with a sorting grille and a levelling bar, allows to bring back soft and refined soil on the surface.

Central and lateral mechanic sealing

The whole range of Alpego Rotary Cultivators features the patented “CENTRAL DRIVE GEAR BOX” made of solid GEARS (no belts, no chains!)

The innovation and uniqueness of the Alpego Rotary Cultivator concept consists on the central transmission that drives the spinning torque from the PTO to the two half rotors through solid gears. This guarantees maximum reliability and less torque dispersion.
Another advantage is the absence of the lateral transmission and therefore a reduction of the overall width.

Central and lateral mechanic sealing

Central and lateral mechanical seals in oil bath allowing for maximum reliability in extreme conditions also in water immersion.
