Claims

In winter, when the soil freezes to a depth of 0.4-0.5 m, the monocular roots are cut from all sides by chain bars. 10 reductions in the number of tractor passes by one. The choice of the depth of soil freezing at least the same area and rational 0.4-0.5 m is due to the fact that the main use of the machine and tractor fleet is the weight of skeletal roots located at the expense of year-round work organization. the depth of 0.2-0.4 m, must be rigid formula of the invention

fixed, frozen with soil on everything. A stump uprooting method, consisting in

dredging the working body into the soil, cutting the roots and extracting the mon, characterized in that, in order to preserve the upper fertile soil layer, the cutting of the roots of the mon is done by freezing the soil to a depth of 0.4-0.5 m, and removing the mon carried out with the time required to thaw the soil to a depth of 0.5-0.6 m.

its extension and not be able to deviate to the side when exposed to the cutting body. Mostly, the bulk of the conductive (skeletal) roots of most species of woody vegetation is located at a depth of 0.2-0.4 m. The stump is left until spring to thaw the soil to a depth of at least 0.5-0.6 m in order to ensure the possibility of combing the cut roots at the entire depth of their bedding.

Removal of stumps that are free of roots is performed when the roots are combed out by root scrubbers, rooting aggregates (harrows) or other machines.

Using the method of uprooting stumps on reclaimed land will ensure minimal impact of the tractor undercarriage on the upper fertile soil layer due to

reducing the number of tractor passes over the same area and making rational use of the machine and tractor fleet due to the year-round organization of work, the Invention Formula
