METHOD FOR AUTUMN SOIL CULTIVATION AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2008 - IPC A01B13/00 

FIELD: agriculture.

SUBSTANCE: method involves cutting mellowed strips with lower halves of ▵-shaped section and upper halves of rectangular section and having width making 2.2-2.6 the width of lower halves; providing mellowed strip interval making 1.5-2.0 the width of their upper halves. Apparatus has frame, carrier wheels and working tools formed as shares fixed on tines, said shares being inclined in vertical-transverse plane. Shares define rows transverse to advancement direction and are grouped in pairs defined by shares of various rows. Lower ends of shares defining pair are arranged in single vertical-longitudinal plane. Rearward and along each row of shares, there are rows of flat knives positioned with their lower ends at the level of mid portion of shares. Knives are arranged in pairs mating pairs of shares so that vertical-longitudinal planes drawn through paired knives are extending peripherally and in equally spaced relation relative to mid portions of shares of mated pair. Combined method and apparatus allow snow retention to be effectively carried out in case of discontinuous mellowing process.

EFFECT: increased efficiency in snow retention and reduced consumption of power for autumn soil cultivation.
