あるため、従来の穴堀機は使用できず、手作業で
周囲を掘り起こして根に土がついたまま移植を行
なつていた。 In conventional hole digging machines, a spiral drill is fixed to the lower end of a vertical rotating shaft to perform drilling work in the ground. However, when transplanting seedlings, it is necessary to transplant the soil as well as the roots of the seedlings, so conventional digging machines cannot be used, and the surrounding area must be dug up manually and transplanted with the soil still attached to the roots. Ta.
