A convex pendulum attached in the radial direction to a vertically rotating disc was fixed as a dedicated component for planting-hole formation. A part dedicated to the release of seeds was newly made on the front side of the rotation. The ratio of skipped holes at 0.82m/s was improved from 19% to 14%. The ratio of two seeds placed in one hole in the original setting was only 40%. One important characteristic of the device is that the planting distance can be set as equal. This feature was used to prepare a test group in which seeding was conducted in zigzags with half the distance between rows and twice the planting distance compared to the standard. The yield per plant as well as per unit of area in this test group was about 15% higher than in another test group using the same planting density, with weed dry weight decreased to 3/4-1/2 that of the other group.

将凸摆沿径向固定在垂直旋转的圆盘上，作为定植孔形成的专用部件。在旋转装置的前侧新制作了一个专门用于释放种子的部件。 0.82m/s时的跳孔率由19%提高到14%。在原始设置中，一孔中放置两颗种子的比例仅为 40%。该装置的一个重要特点是可以将种植距离设置为相等。利用这一特征准备了一个测试组，其中以之字形播种，行距为标准的一半，种植距离为标准的两倍。该试验组的单株和单位面积产量比相同种植密度的另一试验组高约15%，杂草干重下降至另一组的3/4-1/2。
