A lawn mower mower is a machine utilizing one or more revolving blades to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machines wheels. The blades may be powered by muscle, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin, or the machine may have a battery powered or plug inelectric motor. The most common power source for lawn mowers is a small typically one cylinder internal combustion engine. Smaller mowers often lack any form of propulsion, requiring human power to move over a surface walk behind mowers are self propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self propelled walk behind types, or more often, are ride on mowers, equipped so the operator can ride on the mower and control it. A robotic lawn mower lawn mowing bot, mowbot, etc. Two main styles of blades are used in lawn mowers. Lawn mowers employing a single blade that rotates about a single vertical axis are known as rotary mowers, while those employing a cutting bar and multiple blade assembly that rotates about a single horizontal axis are known as cylinder or reel mowers although in some versions, the cutting bar is the only blade, and the rotating assembly consists of flat metal pieces which force the blades of grass against the sharp cutting bar. There are several types of mowers, each suited to a particular scale and purpose. The smallest types, unpowered push mowers, are suitable for small residential lawns and gardens. Electrical or piston engine powered push mowers are used for larger residential lawns although there is some overlap. Riding mowers, which sometimes resemble small tractors, are larger than push mowers and are suitable for large lawns, although commercial riding lawn mowers such as zero turn mowers can be stand on types, and often bear little resemblance to residential lawn tractors, being designed to mow large areas at high speed in the shortest time possible. The largest multi gang multi blade mowers are mounted on tractors and are designed for large expanses of grass such as golf courses and municipal parks, although they are ill suited for complex terrain.
