The invention relates to a motor hoe whose tiller is characterized in that the blades of the tillage knives are made and arranged in such a way that the knives of the inner rows have greater adhesion to the ground than the knives of the outer rows and produce most of the forward thrust. This is achieved by differentiating the construction characteristics of the knife blades with respect to the diameter of the knife stars and the shape, curvature and inclination of the knife blade. Therefore, the tiller exhibits excellent performance in terms of maneuverability, running stability and the ability to plow the soil deeply. Figure to be published with the abstract: figure 1.
