Abstract:
1. A walk-behind working machine comprising: a machine body; a handle extending rearwardly from a rear part of the machine body; a working member mounted on the machine body; an engine supported on the machine body; a regulating mechanism for regulating a throttle for the engine, the regulating mechanism having a pivoting member pivotably attached to the handle and provided with an engagement pin, a throttle wire extending from the throttle and connected at a distal end thereof to the pivoting member, and an engagement member provided to the pivoting member; a first clutch mechanism having a first clutch for connecting or disconnecting drive between the engine and the working member, a first clutch lever pivotably attached to the handle, a first clutch wire extending from the first clutch and connected at a distal end thereof to the first clutch lever, and a first activating member provided to the first clutch lever and configured for engagement with the engagement member of the regulating mechanism to shift the throttle from a first opened position in which an idling engine speed is produced to a second opened position in which a working-machine-activating engine speed is produced to thereby place the first clutch in a connected state; and a selection mechanism operable to selectively engage the first clutch lever with the engagement pin of the pivoting member to thereby connect the drive between the engine and the working member.
