The invention relates to the treatment of the soil in agriculture and forestry, in particular, to plow with vibrating digging or piercing working bodies. Said technical result is achieved in that there is provided a heavy ripper soil that contains a set of wheels K fixed to the rim of each of them in two rows n of knife elements shifted by an angle φ = π / n, wherein the length of the blade member L determined depth of soil treatment, the distance between the ends of the cutter elements in one row D, row spacing d 1 is made equal to the distance d between the sets of wheels 2 and r is defined to specify the size of lumps formed during tillage of the relations, d 1 = d 2 = D / 2 d 1 at ≤r The number of TOY K s wheel is defined plowing width H from the condition d 1 (2K-1) ≥H mass M of each wheel is chosen from the condition of complete immersion knife part elements with an area S t to the ends of the rim with the ground contact area S of the ground strength of not less than r σ 20 x 10 4 n / cm 2, from the condition of Mg / S m> 20 * 10 April ≥ r >> Mg / S o where: D - the distance between the ends of the cutter elements, m d 1 - the distance between the rows of knife elements in one wheel, m d 2 - distance between the sets of wheels, m r - one of the secondary maximum size of lumps formed in soil treatment agitator, m H - H plowing width m M - mass of each wheel kg S t - the area of the ends of the cutter part elements embedded in the soil, m 2Of S - rim area of contact with soil, m 2 σ r - soil strength, N / m 2 g - acceleration of gravity 9.81 m / s 2Полезная модель относится к обработке почвы в сельском и лесном хозяйствах, в частности к плугам с вибрирующими, копающими или прокалывающими рабочими органами. Указанный технический результат достигается тем, что предложен тяжелый рыхлитель почвы, содержащий набор колес К с закрепленными на ободе каждого из них двумя рядами n ножевых элементов, сдвинутых на угол φ=π/n, при этом длина ножевого элемента L определена гл
