FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machine building, particularly to tillage machines for surface treatment of soil, namely to tillage rollers. Agricultural machine with adaptable wheels and rollers comprises first frame and roller with pipe installed on bearings, associated with first frame. Agricultural machine contains second frame and wheel. Second and first frames are interconnected. Wheel comprises rim installed on bearings, associated with second frame. Wheel is equipped with tire fitted on rim. Roller comprises ring around the pipe. Proposed wheel comprises tire tread. Bandage and tread contain recesses, determining elementary pattern, repeating in transverse direction. Repetition pitch in transverse direction elementary pattern roller and repetition pitch in transverse direction elementary pattern wheel are equal to nearly 10 %. Elementary pictures determined ledges with height on roller and height on the wheel is equal to nearly 90 %. Repetition and height of ledges form on soil number of furrows.
EFFECT: such design solution provides uniformity of soil surface, as well as wear resistance of furrow forming elements.
