An example of hand-held, engine-powered bush cutting machines is disclosed in Japanese Patent Laid-Open Publication No. SHO-50-129319. The disclosed bush cutting machine includes a brake device for positively applying, upon removal of power transmission to a cutting blade thereof, a braking force to the cutting blade to prevent rotation under inertia of the cutting blade. The bush cutting machine comprises an operation rod, an engine disposed at a proximal end of the operation rod, a transmission shaft passing through the operation rod and operatively connected with the engine, and a rotary cutting blade mounted to a top end of the transmission shaft. A brake drum mounted to a proximal end of the transmission shaft is housed in a clutch case provided at the proximal end of the operation rod. A pair of brake shoes brakes the drum by press contacting an outer peripheral surface of the drum. These brake shoes are supported by brake elements having links attached to their free ends.
