This research is carried out to analyze the basic characteristics of a “power driven disk plow” and to develop the design theory for reasonable disk plows, recently diffusing in Japan.
In the “Part I”, in order to analyze the basic characteristics of an arbitrary point on the power driven disk plow, the three dimensional motion equations were proposed. The factors considered were the revolutional speed of the disk plow, the traveling speed of a tractor, the gang angle, the radius of the disk plow and so forth. Moreover, theoretical equations to express the motion and the angle factors of an arbitrary point were analyzed, and its characteristics were explained.
