A rotary cutter for a mowing machine includes a cord for mowing grass by rotating, a reel which contains the cord and intermittently rotates to pay out the cord, a case which contains the reel, and a cover which covers the case, wherein the reel includes an upper cam and a lower cam, a stopper is incorporated in the case at a center of a bottom thereof, one end of the stopper is engaged with the upper cam thereby to stop the rotation of the reel, the other end of the stopper is engaged with the lower cam, one end of the cord is engaged with the stopper from outside thereof and guided out of the rotary cutter through a cord guide, and the other end of the cord is guided out of the rotary cutter without touching the stopper.

Rotary cutter for mowing machine

A power transmission mechanism between an engine starter and an engine capable of securely engaging the ratchet wheel of a rotatingly driven part with the lever-like engagement/disengagement member of a centrifugal clutch mechanism when the engine is started. The side face of the lever-like engagement/disengagement member facing the ratchet teeth of a second ratchet part is formed in such a shape that is recessed in a direction apart from the peripheral surface of the second ratchet part in an area starting at its pivoting part toward an engagement/disengagement claw part. The engagement/disengagement claw part formed at the tip of the lever-like engagement/disengagement member is engaged with the ratchet teeth of the second ratchet part by surface contact, and the ratchet teeth of a first ratchet part and the ratchet teeth of the second ratchet part are disposed at a prescribed phase difference.

Power transmission mechanism between engine starting device and engine

A throttle lever device for an engine having a decreased number of parts and capable of facilitating an assembling operation. An operation grip for controlling an engine of a mowing machine or the like is provided on opposite sides thereof with a throttle lever and a lock lever engageable with the throttle lever, respectively. A lock button is arranged in proximity to the lock lever so as to hold the throttle lever at a half throttling position. The throttle lever, lock lever and lock button are arranged so as to be pushable in toward a center of the operation grip. The lock lever and lock button are formed integrally with each other and constantly urged by an elastic member so as to be projected outwardly of the operation grip.
