摘要： Riding lawn mower switchable between mulching and bagging modes includes: a delivery passage for delivering grass, cut by cutting blades in a housing, from the housing to a receptacle by delivering air; and a scroll guide provided in an entrance of the passage for directing the grass clippings to the passage. An overall shape of the scroll guide as viewed in top plan is a substantial isosceles triangle extending into the housing while tapering forward from a scroll guide's base section located in the entrance and as viewed in side elevation is a substantial triangle tapering forward from the base section. Left and right side surfaces of the scroll guide each comprises lower and upper slanting surfaces formed as different slants, each of which gradually increases in area from the distal end of the scroll guide toward the base section.

摘要： A lawn mower includes a cutter blade that cuts grass; a body portion including a housing containing the cutter blade, and a grass clippings discharge passage that discharge grass clippings cut by the cutter blade from the housing; a grass clippings container detachably attached to the body portion, and a slide device. The grass clippings discharge passage includes an upstream opening connected to the housing, and a downstream opening for ejecting grass clippings to outside of the body portion. The grass clippings container includes an opening opened toward the body portion and connected to the body portion, an end surface facing the opening, and a side surface extending from the opening to the end surface. The slide device adjusts a distance between the downstream opening of the grass clippings discharge passage and the end surface of the grass clipping container.
