The harrow (mattock) rotational MRN - 9 is applied for destruction of a superficial crust on the soil, saturation of the soil by oxygen, mulching of the soil for the purpose of preservation of moisture in the soil, a dovskhodovy and poslevskhodovy boronovaniye of crops, destruction of threadlike shoots of weeds, to continuous and interrow processing of crops, seal of fertilizers to the soil after their superficial introduction.
Effective use of a mattock of winter wheat, rotational for a spring boronovaniye.
Working bodies of a mattock create an ideal background for initial development of root system of plants, well mulch the top layer of earth, destroying a soil crust, thereby, keeping moisture, destroy threadlike roots of weeds to 100% at speeds up to 20 km/h. It does possible to pass to bezgerbitsidny technology. At emergence of a monolithic soil crust on early shoots of cultural plants, for example, of corn efficiency of use of a mattock sharply increases in a stage of 2 - 3 leaves when application of zubovy harrows is impossible.
The harrow rotational - is aggregated with propashny tractors of a class from 105 h. p. and above. A way of aggregation – hinged
