After contrasting and optimizing this paper gets a set of parameters. Then according to these parameters the paper sets up entity model, and after validating and analyzing with finite element it can save time of calculating. On the other hand, it can provide a good method of design of moldboard plow surface.

This paper analyses and calculates the plow parameters about two kinds of high speed plows LEMKEN and KUHN, and studys the relation between the geometric parameters of shape of moldboard plow surface and soil properties, plowing quality, forces properties, plowing speed, resistance and energy dissipation during the plowing. Then according to the direction of developing high efficiency and saving-energy agriculture, under the premise of good farming quality this article puts forward a kind of method setting the mathematics model about plow resistance through the new cultivation principle and the new design principle.

While traditional farming experiences and preliminary experiments on minimum tillage showed a preference of alternating furrow slice inverting and deep loosening without inverting in some of the agricultural regions in China, the development of a PTO driven furrow slice inverting rotary plow as primary tillage implement inplace of the conventional moldboard plow was justified from the standpoint of less tractor traffic, less soil compaction, less energy consumption, sowing in time etc.
