The FS (Out of Furrow) system version is designed to work the soil without the tractor wheels passing inside the newly plowed furrow. This system has several advantages: it avoids soil compaction in the furrow, providing better aeration and permeability of the soil; it also allows working closer to field edges and in sloping or difficult soils, improving the quality of plowing. It is especially useful in heavy or wet soils where compaction could reduce crop yield. Side shock absorber system that allows semi-curving in plowing. Available in variants ASI FS 40, 45, 50, to indicate working depth in centimeters, with hydraulic header displacement system. Other variant ASI FSM 35, 40, 45 and 50, indicating working depth in centimeters, with mechanical header displacement system.
