〔実施例〕
以ト、本発明の１実施例を図面に基づいて説明する。In short, according to the present invention, in particular, by providing a grounding roller capable of forced rotational drive between the scraper and the rear running wheel, even if the scraper part is about to be clogged with mown grass, it will not touch the ground. Since it is held down by rollers and raked backwards, there is no stagnation in the event of a blockage, and there is no problem such as rotation due to grass getting caught between the endless cutting blade and wheel, and even long, dense grass can be mowed smoothly and efficiently. [Embodiment] Hereinafter, one embodiment of the present invention will be described based on the drawings.
