PROBLEM TO BE SOLVED: To provide an operation control method for a walking type electric tiller improved in operability by preventing to the utmost the behavior of the electric tiller from becoming unstable when a large load is applied to an electric motor during tilling work, and automatically performing this control.SOLUTION: The operation control method for the walking type electric tiller includes detecting a load applied to the electric motor (2) during tilling work, and stopping the electric motor (2) from normal rotation or low-speed rotation when the load is a required threshold or more while switching the electric motor (2) from normal rotation to low-speed rotation when the load is less than the required threshold.COPYRIGHT: (C)2013,JPO&INPIT【課題】耕耘作業中に電動モータに大きな負荷がかかったとき電動耕耘機の挙動が不安定になることを極力防止し、その制御を自動で行うようにして、操作性を改善した歩行型電動耕耘機の運転制御方法を提供する。【解決手段】耕耘作業中において、電動モータ(2)にかかる負荷を検出し、該負荷が所要の閾値以上であるときは、前記電動モータ(2)を通常回転又は低速回転から停止させ、前記負荷が所要の閾値未満であるときは、電動モータ(2)を通常回転から低速回転に切り替える歩行型電動耕耘機の運転制御方法。【選択図】図5
