These machines process the soil and bury stones, clods, debris and cultural residues with great efficiency, even in difficult conditions and in not previously prepared fields. The inverted rotation of a special rotor (opposite to the forwarding direction) combined with a selector rake and a levelling bar cover the buried material with a fine and clean soil layer. Stone buriers simplify the seeding/transplanting operations of several vegetable- and special crops creating very well formed, stable and porous cultivation beds. This series is very large and it’s composed by single, double, triple fixed and folding/foldable machine to suit every kind of job and tractor power.
