Title: Trimming machine having braking device for cutting blade

Abstract: A trimming machine includes a centrifugal clutch for transmitting power from an internal combustion engine to a cutting blade. A manually operated throttle lever controls an output from the internal combustion engine by adjusting an opening of a throttle valve via a throttle wire. A friction member arranged to oppose to a clutch drum of the centrifugal clutch. A first swinging member is connected to the friction member and swings between a braking position to be pressed against the clutch drum and a releasing position to be spaced from the clutch drum. A second swinging member is connected to a connecting point at an intermediate portion of the throttle wire and pivots about a pivoting pin thereof with respect to the first swinging member when the throttle wire is moved by operating the throttle lever. The throttle wire extends along a bent path which is bent at the connecting point so that the pivoting pin of the second swinging member is moved toward the bent path by a swinging movement of the first swinging member so that the throttle wire has no play when the first swinging member is at the releasing position, and the pivoting pin of the second swinging member is moved away from the bent path by a swinging movement of the first swinging member so that the throttle wire has play when the first swinging member is in the braking position.
