Abstract: A working machine may include a body, a working part, a prime mover, a handle, a trigger member configured to be operated by the user for driving the prime mover; and a lock member. The handle may be configured to shift between a working state and a non-working state. The lock member may be configured to: move between a non-restriction position and a restriction position, be positioned at the non-restriction position when the handle is in the working state, be positioned at the restriction position when the handle is in the non-working state, and move from the non-restriction position to the restriction position in response to shift of the handle from the working state to the non-working state.

Abstract: A lawn mower having a lateral-side discharge outlet in a body housing for discharging mowed lawn has been configured such that a discharge outlet door for closing the lateral-side discharge outlet is held at a closed position only by a spring force, and therefore, there has been a risk of causing fluttering due to a blowing pressure and vibrations generated by the rotation of a mowing blade. An object of the present invention is to avoid fluttering of the discharge outlet door.In order to avoid fluttering, a lock device (20) is disposed at a discharge outlet door (16) for locking it at a closed position. The lock device (20) is unlocked by an unlock operation by the user, so that accidental opening can be prevented. By setting a spring to be weak, the discharge outlet door (16) can be easily opened.
