。A rotary blade attachment consisting of a spindle that transmits power from a drive source built into the main body via a speed reduction device, a rotary blade fixed to the tip of the spindle by a mounting bracket, and a lock pin that locks the rotation of the spindle at appropriate times. In the shaft locking mechanism, a stopper part is formed at the bottom of the lock pin, and a recessed hole part is formed at a position opposite to the stopper part to be perpendicular to the lock pin and engage with the cam flank and the stopper part of the lock pin. A locking mechanism for a rotary cutter mounting shaft, wherein a change lever is disposed, and a locking groove is formed at an outer peripheral end of a reduction gear fixed to the spindle to engage with the lock pin and lock the spindle.
