We made up-cut rotary with two axles (abbreviation ; two axles rotary) for increasing soil-overturning by rotary tillage. In this experiment, the soil overturning and clod size distribution by two axles rotary tillage were investigated. At the same time, we examined the performance of a conventional up-cut rotary. So we can be discussed the comparison of both rotary.The main results were as follows.(1) The mean weight diameter of clod size distribution by two axles rotary tillage was smaller than one of a conventional rotary tillage. This result suggests that the tillage by two axles rotary make pulverization of many times than conventional rotary.(2) The effects of rake rod space and rotational speed ratio of front-rear rotary on soil-overturning were not observed because the clod size was smaller than forecast.(3) The soil displacement ratio from surface layr to lower layr after tillage was 12% in the conventional rotary tillage. On the contrary, its value of two axles rotary was the range of 28.3-36.3%. Therefore, it is assumed that two axles rotary was more useful than a conventional rotary in the soil-overturning properties.(4) The specific torque of two axles rotary showed the values ranging from 0.242to0.329_N・m/cm^2 at upland field experiment.

为了提高旋耕翻土能力，研制了双轴上切旋耕机（简称双轴旋耕机）。试验研究了双轴旋耕土壤翻转和土块粒径分布规律。与此同时，我们研究了传统的上切旋转的性能。因此，我们可以讨论比较两种旋转。主要结果如下。(1)双轴旋耕的土块平均重量粒径小于常规旋耕。这一结果表明，双轴旋耕比传统旋耕使土壤粉化程度提高了数倍。(2)由于土块尺寸小于预测值，耙杆间距和前、后旋轮转速比对翻土的影响不明显。(3)常规旋耕后土壤表层向下层的位移率为12%。而双轴旋转时，其值在28.3- 36.3%之间。因此，它被认为是两个轴旋转比传统的旋转更有用的土壤翻转性能。(4)高地试验中双轴旋转比扭矩为0.242 ~ 0.329_N·m/cm^2。
