FIELD: agricultural engineering, in particular, disk tillage tools functioning in existing and newly manufactured body, frame, rotational and battery type special narrow and wide harrows, cultivators and drills.
SUBSTANCE: tillage tool has disk with cutting edges. Polyurethane layer is placed within disk, on its bottom. Holder provided on the top of layer is fixed in conjunction with said layer within disk bottom. Mounting slots are formed within holder, the parts of slots disposed closer to holder center functioning as fixing members. Slots of greater width with lateral depressions are axially aligned with mounting slots, said depressions serving as guiding members. There are blades with shank fixing parts within each slot. Cutter is provided in lower end of blade pole. Platform for mounting of tillage sections is disposed at two sides of cutter. Opening for drive device is formed in disk and holder. Holder has openings for mounting of tubular shape levelers with flanges within inner cavity, said flanges being provided with pins.
EFFECT: wider constructional, processing and operational capabilities of tillage tool.
