Erpice rotante multistrato da impiegare in agricoltura per preparare perfettamente, economicamente ed in una sola passata il terreno secondo la stratificazione differenziata ideale per la semina, od il trapianto rompendo più grossolanamente il terreno in profondità e sminuzzandolo più finemente in superficie, basato per il suo funzionamento su più schiere successive di utensili rotanti secondo assi sensibilmente verticali, ciascuna con una sua profondità di passata e con una sua intensità di frantumazione del terreno, disposte, dal punto di vista del lavoro, in ordine decrescente di profondità di passata e crescente di intensità di frantumazione.Multilayer rotary harrow to be used in agriculture to prepare the soil perfectly, economically and in a single pass, according to the differentiated stratification ideal for sowing or transplanting, roughly breaking the soil in depth and chopping it finer on the surface, based on its functioning on several successive arrays of rotating tools according to significantly vertical axes, each with its own depth of pass and with its intensity of crushing the soil, arranged, from the point of view of the work, in decreasing order of depth of pass and increasing intensity of crushing.
A direct-connected, reversible, single-bottom plough with subsoilers, provided with a differential surface-ploughing device allowing surface soil to be put into the furrow at programmable intervals, and with reversible sowing members
