Abstract
An electric working machine may include a support rod extending in a front-rear direction; a head unit attached to a front end of the support rod and including a front tool and a motor configured to drive the front tool; and a grip unit attached to a rear end of the support rod. The grip unit may include a grip housing configured to be gripped by an operator; a detection sensor attached to the grip housing and configured to detect an on/off operation for the motor by the operator; and a presence sensor attached to the grip housing and configured to detect a grip by the operator on the grip housing. The support rod may not penetrate through the grip housing. In a rear plan view of the electric working machine, at least one of the detection sensor and the presence sensor at least partially may overlap the support rod.
