Abstract: An electric working machine may include a support rod, a head unit, a position fixing mechanism, and a resistance member. The support rod may extend in a front-rear direction and include an attachment portion located at a front end of the support rod. The head unit may include a front tool, a motor configured to drive the front tool, and a head housing supporting the front tool and coupled to the attachment portion rotatably about a rotation axis. The position fixing mechanism may be configured to fix a rotation position of the head unit with respect to the support rod. The resistance member may be interposed between the attachment portion and the head housing with respect to a direction perpendicular to the rotation axis. The resistance member may be configured to provide a resistance force against rotation of the head unit with respect to the support rod.
