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.

本文通过对比分析的手段对LEMKEN和KUHN两种高速犁参数两种犁体曲面参数进行量化分析计算，分析犁体曲面形状的几何参数与耕后质量、土壤的力学特性、耕速、阻力和功率消耗等相关关系，结合目前高效节能型农业的发展方向，提出在保证作业质量的前提下，应用新型耕作理论和新型设计理论建立牵引阻力数学模型。

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.

从翻耕或翻耕与深松相交替将在相当广大的地区、相当长的时期内，作为一种基本的田间作业环节而存在这一认识出发，用"假想旋翻垡片"的概念研究了旋翻在几何尺寸上的可能性及其限制条件，并从保省耕作法的节能、赶农时、省人工减少土壤压实、经济高效等方面对旋翻进行了考察，指出发展一种动力驱动、原沟旋转翻垡的基础耕具的必要性和可行性。

This paper makes the soil movement be four sections: a Cutting soil with edge; bThe soil movement along the plowshare and plow chest's below surface; c The soil movement along the plow cliff ;dThe soil movement beyond the plow in the course of farming in order to study the force of moldboard plow surface.

本文在研究犁体曲面受力时，把犁耕时土垡的运动分为四个阶段：a 用铧刃切开土垡；b 土垡沿犁铧和犁胸下部曲面运动；c 土垡沿犁壁运动；d 土壤超出犁壁曲面运动。
