Among crops cultivated in farmland, soybean is also called soybean and is widely cultivated as a food crop.

These beans sometimes grow straight with a stem height of 60 to 100 cm, and there are also some climbing varieties.

Here, the fruit of the bean contains many seeds in a line-shaped flat pod, and when the bean is fully ripe, the pod bursts and the seeds are scattered.

Therefore, cutting off the stems must be performed before the fruits are fully ripe.

In the past, since the stems of beans were manually cut, there was a problem in that considerable labor was required and labor costs were increased.
