Pushed and engine powered lawn mowers, common mowers used by customers
There are two main lawn mower types. Those where a set of cylindrical blades spin in a vertical forwards motion, and those whose blades spin horizontally. In the United States, the first gasoline powered mowers were manufactured in 1919. This lawn mower type is the most commonly used customers, although versions with electric motors are becoming increasingly popular.
Types of lawn mowers
The simplest kind of lawnmowers and easy to use is the manual push lawn mower. These mowers always use the cylindrical type blades. This works by spinning the cutting blade at a fast speed, with power supplied by the user pushing behind it, rotating its wheels, which are then geared to the cutting blades. The blade rotates forward over the grass, pulling it into the blade and against a fixed plate; the blade and plate cause a scissor-like slicing action which cuts the grass.
The simplest type of power lawn mower is basically, the same push lawnmower with an engine. The engine works for us and we don not have to work as hard as in manual push lawnmowers. The engine rotates the cutters and drives the machine forward. Nowadays and since last twenty years, it is also common to find this type of mower with an electric engine. It is used as the power source, though this has the disadvantage of requiring a trailing power cord which limits its range, so these are only useful for relatively small lawns close to a power socket. There is also the obvious hazard with these machines of the possibility of mowing over the power cable.
Today, new technology is bringing us improved mower versions. Low emission gasoline engines with catalytic converters are being manufactured to help reduce air pollution. Improved muffling devices are also being installed to reduce the noise pollution. Battery powered mowers are also becoming practical. Although slightly smaller with an average cutting swath of only 17-19", these new mowers will quietly cutting lawns without the common cloud of blue smoke hanging in the air, for about an hour per charge. Prices are comparable to a high-end gasoline powered lawn mower.
