Work depth regulation through the articulation of the wheels, driven by the tractor's hydraulic system. The depth range is determined by the number of strokes limiting shims, located on the rods of the two hydraulic cylinders.
With parabolic geometry, the subsoiling arm is a tool that breaks up the compacted layer of soil without causing excessive revolving, keeping a large part of the plant residues on the surface, improving porosity and water infiltration. It is composed of a safety system that disarms the arm by means of a flat spring whenever it encounters any obstacle. To rearm it is automatic, just lift the subsoiler, making the maintenance of the system a simple operation and consequently obtaining greater yield and lower operating costs.
It follows the topography of the land, reducing the size of the clods and leveling the surface of the worked area, with a system of articulated supports and helical springs that cause effective compression to the soil, regardless of the topography of the area.
