Lawn mower

Abstract

A lawn mower (10, 100) has a scroll portion (11d) for allowing grass clippings to swirl within a housing (11) while guiding them to a grass discharge passage (21). A guide (70, 170) provided beneath a top plate (11a) of the housing is placed along the scroll portion. A rear guide end (71, 171) of the guide is opposed to a passage opening (24) facing the housing of the grass discharge passage. The direction of a swirling flow is gradually changed and guided toward the passage opening by the guide. A pivotal shutter (40) pivotal about a generally vertical axis is provided for opening and closing the grass discharge passage (21).
