Improved rotating agricultural tool, characterized essentially by the fact that each independence of the peripheral alternative arrangement of the two groups of blades that define a theoretical rotating cylinder, supported by three equidistant plates, comprising radial support legs of said blades, the the plate corresponding to the area of connection with the machine, is constituted by a spherical cap prolonged in its bottom by a cylindrical sleeve and in its periphery by four radial legs of support of the blades.
