FIELD: agriculture. ^ SUBSTANCE: roller (10) comprises a tubular support structure (14), an axis (X-X) which is located horizontally and can be mounted with the ability of rotation on the towed support frame. The support structure comprises a set of pneumatic tires (12) of half-empty type put on this tubular support structure. The tires have a profile of the given shape, in particular, the arched profile which enables to form in the soil a set of parallel grooves. Tubular support structure (14) comprises fittings formed by the plurality of rods (30). The rods are interconnected by two circular end sides (32). The rods pass between the side walls in the axial direction. Pneumatic tires (12) are mounted on the fittings rods to form together with the fittings the system rigidly connected on the rotary movement and the progressive movement. ^ EFFECT: constructive implementation enables to reduce the roller metal consumption, which in turn enables to reduce the sealing impact of roller on the soil, as well as to increase the efficiency of the roller operation. ^ 15 cl, 16 dwg |
