A top harvester has a wheel frame mounted thereon in series: a horizontal rotor with knives, a cleaner of root heads from top remains, as a horizontal shaft with sections, on the flanges of which axles with flexible beaters forming blades and cutters of root heads are fixed. In each section of the cleaner of root heads projections of even axles onto horizontal plane are turned relative to the shaft for an angle L to the right, and projections of the odd axles for an angle L on the left. In addition, the left ends of the even axles are fixed on the flanges of the sections evenly along the circumference of a lesser diameter d, and the right ones of a larger D one, and the odd axles on the contrary. The projections of the even axles of one section form an obtuse anglewith the projections of the odd axles of the adjacent sections. |
