Abstract: A grass collection container for a lawnmower is provided to reduce the amount of blockage in an air-permeable region of the container. Materials, such as residual grass, that adhere to the container, cause the blockage. The grass collection container is made from cloth, sewn in the form of a bag, to collect grass that has been cut by a rotating cutting blade of the lawnmower and carried to the container by a flow of air. At least one section of the grass collection container is the air-permeable region that allows the flow of air to pass therethrough but does not allow the grass to pass therethrough. The air-permeable region carries thereon a photocatalyst that sterilizes and decomposes grass and organic materials. Therefore, the container is able to reduce the amount of blockage and suppress decay therein, thereby lowering the level of unpleasant odors.

Abstract: A gas engine operated machine includes a machine unit that includes an engine burning a gas fuel, and a working device driven by the engine, the machine unit being surrounded by and fixed to a rigid frame formed by framing an elongated frame material, and an upper portion of the machine unit being covered with a roof, such that the operated machine is easy to handle and attractive in appearance, and it is possible to effectively avoid another object colliding against piping parts such as a gas fuel pressure regulator and the like, or rain water, dust and the like striking against the piping parts, thereby stabilizing the operation of the piping parts and enhancing the durability of the piping parts. A roof includes an upper cover bulged upwards, and a lower cover mounted to a lower surface of the upper cover, and supported on a rigid frame through vibration-damping members.
