Excerpt: A lawn mower is a machine that uses a revolving blade or blades to cut a lawn at an even length. Lawn mowers employing a blade that rotates about a vertical axis are known as rotary mowers, while those employing a blade assembly that rotates about a horizontal axis are known as cylinder or reel mowers. Many different designs have been made, each suited to a particular purpose. The smallest types, pushed by a human, are suitable for small residential lawns and gardens, while larger, self-contained, ride-on mowers are suitable for large lawns, and the largest, multi-gang mowers pulled behind a tractor, are designed for large expanses of grass such as golf courses and municipal parks.

The first lawn mower was invented by Edwin Budding in 1827 in Thrupp, just outside Stroud, in Gloucestershire. Budding's mower was designed primarily to cut the lawn on sports grounds and extensive gardens, as a superior alternative to the scythe, and was granted a British patent on 31 August 1830. It took ten more years and further innovations to create a machine that could be worked by animals, and sixty years before a steam-powered lawn mower was built. The first machine produced was 19in in width with a frame made of wrought iron. The mower was pushed from behind with the motive power coming from the rear land roller which drove gears to transfer the drive to the knives on the cutting cylinder; the ratio was 16:1. There was another roller placed in between the cutting cylinder and the land roller which was adjustable to alte
