Claims (2)
- 機体を走行させながら刈り取り作業を行う刈刃付き電動作業機であって、
刈刃と、
前記刈刃を回転駆動する電動モータと、
前記電動モータに電力を供給する主電源と、
前記電動モータと前記刈刃との間で動力を断接するクラッチと、
前記機体の傾斜を検知する傾斜センサと、
前記主電源のON/OFFを制御する制御手段とを備えており、
前記クラッチを操作する操作手段により、前記電動モータの動力が前記刈刃に伝達されない前記クラッチを切った状態と前記電動モータの動力が前記刈刃に伝達される前記クラッチが繋がった状態とを切り換え可能であり、
機体の走行方向と直交する方向を水平方向とし、水平面上の前記機体を正面から見たときの前記機体の垂直方向の中心線を基準線とすると、
前記制御手段は、前記水平方向において、前記基準線が規定角度以上傾斜したとき又は前記通電中の電動モータの回転が規定時間以上停止したときに、前記主電源をOFFにし、
前記電動モータの回転が停止した直後に前記クラッチを切り、前記電動モータが回転しても、前記機体を傾けて前記基準線が規定角度以上傾斜したときに主電源がOFFになることを特徴とする刈刃付き電動作業機。 - 前記操作手段と前記刈刃との位置関係が、作業者が操作手段により前記クラッチが繋がった状態を保持したままでは、前記作業者と同一作業者が前記刈刃近傍の刈草を除去することができない位置関係である請求項1に記載の刈刃付き電動作業機。
