Anti-erosion package-combined tilling and sowing machine for strip tillage on the slope

The paper describes a highly productive resource-saving anti-erosion combined agricultural machine for strip tillage of eroded soils on the slopes. The machine treats only the strips intended for sowing of certain width (20-30 cm) and depth (15-25 cm) without overturning. The border strips are resting, and they are to be treated in the years to come. The machine performs 6-8 agricultural operations during one field day; its working organs are arranged in two packages on the single common frame. The working organs of first package (hanging knives, deep tiller blades, covering knife and harrow) perform the loosening of soil layer without its overturning. The working organs of second package (sowing machine and packing wheels) perform the sowing and packing of plowed strip. The machine is a three-row one. The row-width spacing is 70 cm; the overall operating width is 170 cm; the plowing depth is 15-25 cm; the operating rates are 7-9 km/h; the hourly efficiency is up to 1.5 ha/h. The package-combined machine can be aggregated with tractors of 1.4-3.0 drawbar category. Due to the formation of mini inundation canals and maximum retaining of stubble on soil surface, the moisture is preserved in the soil for a long period of time, that leads to the thickening of humus layer of soil, to retarding of development of erosion processes, and as a result to the increase in productivity. Since the output per shift of the proposed tilling and sowing machine is by 2-2.5 times higher than under tillage by means of commonly used plows, and the consumption of combustive and lubricating materials and environmental pollution by exhaust gases are by 2-2.5 times lower, the machine should be considered not only as energy and resource-saving, but as environment-oriented one.
