Low the harnessed implement to a flat surface until the embedding legs touch it and the depth control wheels are in the air 降低安装设备放置平面直到接触到掩埋臂，并且深度控制轮悬空。
2.
Measure the spacing between the bottom of depth wheels and the surface ? the result is approximately the embedding depth 测量深度控制轮底部与安装设备放置平面的距离就为大致的埋设深度。
