The new E-DUE 2-sided cultivator is ideal for ecological weeding in large acreage vineyards. Its automatic adjusting system makes possible cultivation at slow or high work speeds. Four electro-hydraulic sensors with independent hydraulic distributor adjust a row-centering positioner to ensure good in-and-out movement of the working elements. Each working head is mounted on a special vertical axle system which enables cultivation even in very close plant spacings (50cm/20”).
