FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agriculture and can be used in agricultural seeding machine. Pressure roller (1) for agricultural seeding machine (2) consists of outer rounded tire (3) and inner hub (4) to accommodate roller bearing (5). Tire (3) diameter is a multiple of its width, at that, between tire (3) and hub (4) passes at least one rib element (6) for direction and stabilization of tire (3). Rib element (6) is surrounded by filler (7) made of elastic or resilient material and forming connection between tire (3) and hub (4). Filler (7) provides connection with geometrical closure or non-detachable connection in area between hub (4) and rib element (6) and/or between rib element (6) and tire (3). At that, filler (7) has continuous and/or smooth side sides shape.
EFFECT: invention improves self-cleaning of pressure roller and reduces adhesion of moist soil mass to roller surface.
