Abstract
A rotary cutter for a mower is provided wherein the cord delivering operation, which is necessary when the free end of the cord is worn, is carried out only when the rotary cutter is rotated at a low speed or is stopped. The rotary cutter includes a cord for cutting grass upon rotation thereof, a reel which holds the cord and allows delivering of the cord while the reel is intermittently rotated, a cover for a case which houses the reel, and a press body which protrudes downwardly from the case and is movable in an axial direction upon pressing so as to intermittently rotate the reel. A return spring for biasing the press body in a direction to protrude the press body from the case between the reel and the press body is also provided. The press body and the case engage each other such that the press body is slidable in an axial direction while preventing relative rotation with each other. By pressing the press body against the biasing return spring, a set of protrusions formed on the press body are detachably engaged with protrusions formed on the reel so as to intermittently rotate the reel.
