Abstract: The paper describes an anti-erosion strip-tilling machine, which is capable of performing 5…7 operations simultaneously during one field day. Only those strips with a width of 15…25 cm and depth of 15…25 cm are treated, which are to be seeded. The other strips with a width of 30…40 cm remain unplowed. The expenditures for oils and lubricants and working hours are reduced 2-3 fold, and agrotechnical terms are shortened as well.

  The fields with a tilt angle within a range of 0…8 degrees can be treated by the proposed machine. The plowing working tool,which comprises the passive and active (rotary plow or tiller) working members can operate in three modes: (1) On the eroded soils without furrow slice overturning; (2) On the non-eroded soils by crushing and mixing of clod; (3) On the humid soils with partial overturning of furrow slice (when the rotary plow is mounted in the place of tiller).

  The tillage tool is mounted on the frame with the possibility of regulating the approach angle towards the soil that allows for reducing plowing resistance of soil. The mini-firths created by longitudinal windrows are intended for interception of precipitation and irrigation water and wetting the plowed strips that allows for preventing the ablation of the field surface and the development of water erosion processes.
