摘要： A lawn mower includes: a rotation shaft extending vertically in a downwardly-opening housing; and a cutter blade rotatably mounted on the rotation shaft. The cutter blade is an elongated member extending in opposite horizontal directions and having two bent sections formed on respective ones of its longitudinally opposite end portions. The two bent sections are bent in opposite directions as viewed in the axial direction of the rotation shaft. The cutter blade has, on each of the bent sections, a convex cutter blade section formed along a convex edge of the bent section and a concave cutter blade section formed along a concave edge of the bent section. The convex cutter blade section on each of the bent sections has a smaller cutting edge angle than the concave cutter blade section.

摘要： A noise suppression system for an air-cooled internal combustion engine is disclosed. The system may include an acoustically designed shroud forming a cavity and configured for attenuating noise produced by a cooling air fan associated with the engine. In one system, the shroud is mountable on a housing of the air fan. A pair of air inlet passages may be provided which are operable to draw ambient cooling air into the shroud to the fan. The air inlet passages are acoustically configured and tuned to attenuate noise generated by the fan. In one system, the air inlet passages may each be formed in a rear quadrant of the shroud. Various configurations of the shroud may include quarter wave resonators and/or micro-perforated panels to further attenuate fan noise.

摘要： A bush cutting machine with a tubular operating pole connected to an outlet of an exhaust muffler and doubling as an exhaust passage is provided. Exhaust gases discharged from an engine flow from the exhaust muffler through the operating pole and are then discharged into the air. The substantial capacity of the exhaust muffler is increased by the operating pole, and the exhaust noise of the engine is reduced.

摘要： A cutting line for brush-cutting, edge-trimming and similar has a generally circular cross-section and, on its periphery, has a plurality of notches spaced apart by a distance of between 12 and 19 mm approximately and aligned along at least one direction parallel to an axis of the line, the length of the notches, measured along the line, being substantially shorter than the spacing distance. The cutting line permits a reduction in the operating noise of vegetation cutting devices such as edge-trimmers, brush-cutters, etc.
