Resumen
A tool and method for the decompaction of the surface of slopes. The present invention relates to a tool for preparing the soil during the completion stage of the construction of slopes and other slope maintenance operations, particularly that of aiding revegetation and reducing erosion. The tool presents a roller (1) into which diametrically symmetric rods (8) are inserted, forming pairs of spikes (2), asymmetric diametrical rods (7) or radial rods (6) that generate spikes (2) that project from the surface of the roller (1). The roller is inserted into a fork (4) by means of bearings (3) that enable it to rotate freely, with no need for mechanical traction and elements for the coupling thereof to the articulated arm of a civil works or agricultural machine. The invention likewise relates to a method for preparing or maintaining the surface of slopes that includes the use of the tool of the invention.
