A lawn mower may be a person or machine that cuts (mows) grass or alternative plants that grow on the bottom. sometimes mowing is distinguished from reaping, that uses similar implements, however, is that the ancient term for harvest home grain crops, e.g. with reapers and combines.

A smaller {mower|lawn lawn mower|garden tool|lawn tool} used for lawns and sports grounds (playing fields) is termed a garden tool or grounds mower, that is usually self-powered or might also be sufficiently little to be pushed by the operator. Grounds mowers have a reel or rotary cutters. Larger mowers or mower-conditioners are primarily accustomed cut grass (or alternative crops) for fodder or ensilage and infrequently place the cut material into rows, that are noted as windrows. Swathers (or windrowers) are accustomed cut grass (and grain crops). before the invention and adoption of mechanized mowers, (and these days in places wherever use a lawn mower is impractical or uneconomical), grass and grain crops were cut by hand victimization scythes or sickles.
