Lawnmowers
A lawn mower (also known as a mower, grass cutter or lawnmower) is a device utilizing one or more revolving blades (or a reel) 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 machine's wheels. The blades may be powered by manual force, 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-in electric motor. The most common self-contained 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" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawn
A lawn is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawnmower (or sometimes grazing animals) and used for aesthetic and recreational purposes. Lawns are usually composed only of grass species, subject to weed and pest control, maintained in a green color (e.g., by watering), and are regularly mowed to ensure an acceptable length. Lawns are used around houses, apartments, commercial buildings and offices. Many city parks also have large lawn areas. In recreational contexts, the specialised names turf, pitch, field or green may be used, depending on the sport and the continent. The term "lawn", referring to a managed grass space, dates to at least than the 16th century. With suburban expansion, the lawn has become culturally ingrained in some areas of the world as part of the desired household aesthetic.Robbins, PaulLawn People: How Grasses, Weeds, and Chemicals Make Us Who We Are P ...

Ransomes, Sims & Jefferies
Ransomes, Sims and Jefferies Limited was a major British agricultural machinery maker also producing a wide range of general engineering products in Ipswich, Suffolk including traction engines, trolleybuses, ploughs, lawn mowers, combine harvesters and other tilling equipment. Ransomes also manufactured Direct Current electric motors in a wide range of sizes, and electric forklift trucks and tractors. They manufactured aeroplanes during the First World War. Their base, specially set up in 1845, was named Orwell Works. Ransomes' railway equipment business was hived off in 1869 with a different ownership as Ransomes & Rapier and based nearby at Waterside Ironworks. History 18th century The enterprise was started by Robert Ransome (1753–1830), who was born into a Quaker family in Norfolk, and became an apprentice to an ironmonger in Norwich. The Quaker values of frugal living, avoiding debt and keeping regular accounts served him well when he set up one of the first brass and ...

Zero-turn Mower
A zero-turn riding lawn mower (colloquially, a ''z-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 drive wheel being the most common method when a gasoline or diesel engine is used. Battery-powered models simply use two electric motors. Both commercial duty and homeowner models exist, with varying engine power options, size of cutting decks, and prices. A z-turn mower typically drives faster and costs more than a similarly sized conventional riding mower that has steerable front wheels. Most current models have four wheels: two small swiveling front tires and two large drive tires in the back. Bush Hog (, Inc. of Selma, Alabama) mowers sometimes come with a small, pivoting fifth wheel mounted in the center behind the driver. Instead of controlling the swiveling ...

Single-cylinder 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, go-karts, all-terrain vehicles, radio-controlled vehicles, portable tools and garden machinery (such as lawnmowers, cultivators, and string trimmers). Single-cylinder engines are made both as 4-strokes and 2-strokes. Characteristics Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine requires a heavier flywheel than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robotic Lawn Mower
A robotic lawn mower is an autonomous robot used to cut lawn grass. A typical robotic lawn mower (in particular earlier generation models) requires the user to set up a border wire around the lawn that defines the area to be mowed. The robot uses this wire to locate the boundary of the area to be trimmed and in some cases to locate a recharging dock. Robotic mowers are capable of maintaining up to of grass. Robotic lawn mowers are increasingly sophisticated, are self-docking and some contain rain sensors if necessary, nearly eliminating human interaction. Robotic lawn mowers represented the second largest category of domestic robots used by the end of 2005. In 2012, the growth of robotic lawn mower sales was 15 times that of the traditional styles. With the emergence of smart phones some robotic mowers have integrated features within custom apps to adjust settings or scheduled mowing times and frequency, as well as manually control the mower with a digital joystick.

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag Inclusion (mineral), inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to structural failure, failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welding, forge welded, but is more difficult to welding, weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is Carbon steel#Mild or low-carbon steel, mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Zoo
London Zoo, also known as ZSL London Zoo or London Zoological Gardens is the world's oldest scientific zoo. It was opened in London on 27 April 1828, and was originally intended to be used as a collection for science, scientific study. In 1831 or 1832, the animals of the Tower of London#Royal Menagerie, Tower of London menagerie were transferred to the zoo's collection. It was opened to the public in 1847. Today, it houses a collection of 673 species of animals, with 19,289 individuals, making it one of the largest collections in the United Kingdom. The zoo is sometimes called Regent's Park Zoo. It is managed under the aegis of the Zoological Society of London (established in 1826), and is situated at the northern edge of Regent's Park, on the boundary line between the City of Westminster and the borough of London Borough of Camden, Camden (the Regent's Canal runs through it). The Society also has a more spacious site at Whipsnade Zoo, ZSL Whipsnade Zoo in Bedfordshire to which t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (sports Field)
A pitch or a sports ground is an outdoor playing area for various sports. The term ''pitch'' is most commonly used in British English, while the comparable term in American and Canadian English is playing field or sports field. For most sports the official term is field of play, although this is not regularly used by those outside refereeing/umpiring circles. The field of play generally includes out-of-bounds areas that a player is likely to enter while playing a match, such as the area beyond the touchlines in association football and rugby or the sidelines in American and Canadian football, or the "foul territory" in baseball. The surface of a pitch is most commonly composed of sod (grass), but may also be artificial turf, sand, clay, gravel, concrete, or other materials. A playing field on ice may be referred to as a ''rink'', for example an ice hockey rink, although ''rink'' may also refer to the entire building or, in the sport of curling, to either the building or a parti ...
