FIELD: agricultural engineering; soil-packing rollers. ^ SUBSTANCE: frame of soil packing roller-ridge former is made sectional with possibility of changing distance between side beams which are interconnected by adjusting mechanism. Rings are made with diameter decreasing from edges to middle of axle. Springs of equal rate and size are installed on axle between rings. Thanks to it quality of soil cultivation is improved owing to possibility of formation of different sections of ridges depending on requirements of crop. ^ EFFECT: reduced labor input at servicing of roller. ^ 2 dwg |
