ABSTRACT:
A rolling hoe apparatus having a hub, shaft, bearings and a plurality of cultivating teeth, arranged into at least one hoe wheel and suspended from a bearing structure such that the axis (15) of rotation of the hoe-body (3) encloses an angle with the normal to the ground-surface in a range of 0.degree.-75.degree.when viewed in the plane of direction of advance (19), while the lateral tilting of the hoe-wheel with respect to the plane perpendicular to the direction of advance (19) lies in the range between 3.degree. and 75.degree., wherein the teeth (7) are arcuated and extend radially from the hub and are bent backwards in relation to the natural sense of rotation (14) during cultivation and are arranged so that in course of hauling they penetrate into the soil (24) and perform a motion crossing the direction of progress, and that the symmetry axis (25) of the cross-section (16) of the teeth (7) penetrating into the soil is adjusted so in relation to the axis of rotation (25), that at the moment of reaching the soil (24) a vertical motion is performed, that means that the angle (.alpha.) enclosed by the plane of rotation (26) of the hoe-wheel (6) and the soil-surface is equal to the angle (.gamma.) enclosed by the symmetry axis of the tooth-cross-section (16, 16a) and the axis of rotation.
