A residential riding or "ride-on" mower. A battery-powered robotic lawn mower. A commercial zero-turn mower. A lawn mower (also known as a grass cutter or simply mower, also often spelled lawnmower) is a device utilizing one or more revolving blades (or a reel) to cut a grass surface to an even height.
DKW RT 250 (1952–1953) motorcycle engine. A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder.This engine is often used for motorcycles, motor scooters, motorized bicycles, go-karts, all-terrain vehicles, radio-controlled vehicles, power tools and garden machinery (such as chainsaws, lawn mowers, cultivators, and string trimmers).
Industrial. In the extraction of petroleum (and other heavy-duty fluid handling contexts), a choke valve (or "choke") is an adjustable flow limiter that is designed to operate at a large pressure drop, at a large flow rate, for a long time. A choke is often a part of the "Christmas tree" at the wellhead. The most familiar choke design is a ...
Small engine. A small engine is the general term for a wide range of small-displacement, low-powered internal combustion engines used to power lawn mowers, generators, concrete mixers and many other machines that require independent power sources. [1] These engines often have simple designs, for example an air-cooled single-cylinder petrol ...
Crankcase ventilation system. A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past ...
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. [3] 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 ...
Zero-turn mower. A zero-turn riding lawn mower (colloquially, a z-turn or zero turn) is a standard riding lawn mower with a turning radius that is effectively zero when the two drive wheels rotate in opposite direction, like a tank turning in place. Different brands and models achieve this in different ways, with hydraulic speed control of each ...
Sankey diagram. Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property. Sankey diagrams can also visualize the energy accounts, material flow ...
