Tractor Plough with Repeated Cutting Angle on Working Elements.

The yield of grain crops by 25% depends on the quality of soil tillage. The working elements of plough-cultivators that exist today are not able to deal with solid and over-dried soil. This is because a flat ploughshare has a constant cutting angle along its entire length that spalls large pieces of soil. Therefore, to improve the crumbling of soil a wedge-shaped working element with a variable cutting angle is developed. The proposed form of ploughshares for plough-cultivators working elements with increasing cutting angles on each part activates additional forces inside the tilled soil layer. This ensures a greater interaction of soil and its better crumbling; the innovative working element with repeated variable cutting angles activates the internal potential of soil. As a result, it changes its inner structure, and its nutrients are better digestible by plants. The developed working element is 20-50 % more efficient than the series ones as it ensures better crumbling of soil. It is patented in the Russian Federation. [ABSTRACT FROM AUTHOR]
