Notes	When the effects of the edge curve of rotary vertical straight blade on the cultivating characteristics are studied, especially concerned with the cultivating resistance, it is necessary to know the operational rotating angle for the analysis of experimental data. The operational rotating angle means the rotating angle of a blade from the beginning to the end of the soil cutting during one rotation. In this paper, as a preliminary knowledge for these studies, the theoretical equations for the calculation of operational rotating angle of a blade were deduced from the geometrical characteristics of a rotating shaft under the fixed and traveled condition. Subsequently, the calculating values which are obtained by the substitution of certain values of the cultivating condition to these equations were compared with the measured values which were obtained from the drawings. Consequently, it was shown that there was not a large difference between both values even in the case of the rotating shaft under traveling condition. In other words, this approximation is reasonable in establishing the theoretical equations of the operational rotating angle.
