A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA), targeting a 2008 introduction. On July 8, 2007, a prototype 787 without major operating systems was rolled out; subsequently the aircraft experienced multiple delays, until its maiden flight on December 15, 2009. Type certification was received in August 2011, and the first 787-8 was delivered in September 2011 before entering commercial service on October 26, 2011, with ANA.
A lawn mower is a device 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 mechanism 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 the blades spin when the mower is pushed forward, 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 4-stroke internal combustion engine. Smaller mowers often lack any form of self-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 that the operator can sit on and control. A robotic lawn mower is designed to operate either entirely on its own or less commonly by an operator on a remote control.
A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
A trailer is an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials.
A snowplow is a device intended for mounting on a vehicle, used for removing snow and ice from outdoor surfaces, typically those serving transportation purposes. Although this term is often used to refer to vehicles mounting such devices, more accurately they are known as winter service vehicles, especially in areas that regularly receive large amounts of snow every year, or in specific environments such as airfields. In other cases, pickup trucks and front end loaders are outfitted with attachments to fulfill this purpose. Some regions that do not frequently see snow may use graders to remove compacted snow and ice off the streets. Snowplows can also be mounted on rail cars or locomotives to clear railway tracks.
Emergency vehicle lighting, also known as simply emergency lighting or emergency lights, is a type of vehicle lighting used to visually announce a vehicle's presence to other road users. A sub-type of emergency vehicle equipment, emergency vehicle lighting is generally used by emergency vehicles and other authorized vehicles in a variety of colors.
The John Deere Gator is a family of small all-terrain utility vehicles produced by the John Deere Corporation. Gators typically feature a box bed, similar in function to a pickup truck. The bed can also be installed as an electric dump body. The John Deere Gator has been made in a variety of configurations, with either four, five or six wheels. The Gator line of vehicles are designed to serve on farms, worksites, and ranches, rather than as a pure off-road vehicle. However, it is possible to order with specific off-road features. Introduced in 1992, the vehicle replaced the five-wheeled John Deere AMT line introduced in 1987.
In aviation, pushback is an airport procedure during which an aircraft is pushed backwards away from its parking position, usually at an airport gate by external power. Pushbacks are carried out by special, low-profile vehicles called pushback tractors or tugs.
An artillery tractor, also referred to as a gun tractor, is a specialized heavy-duty form of tractor unit used to tow artillery pieces of varying weights and calibres. It may be wheeled, tracked, or half-tracked.
A winter service vehicle (WSV), or snow removal vehicle, is a vehicle specially designed or adapted to clear thoroughfares of ice and snow. Winter service vehicles are usually based on a dump truck chassis, with adaptations allowing them to carry specially designed snow removal equipment. Many authorities also use smaller vehicles on sidewalks, footpaths, and cycleways. Road maintenance agencies and contractors in temperate or polar areas often own several winter service vehicles, using them to keep the roads clear of snow and ice and safe for driving during winter. Airports use winter service vehicles to keep both aircraft surfaces, and runways and taxiways free of snow and ice, which, besides endangering aircraft takeoff and landing, can interfere with the aerodynamics of the craft.
Troll Airfield is an airstrip located 6.8 kilometres (4.2 mi) from the research station Troll in Princess Martha Coast in Queen Maud Land, Antarctica. Owned and operated by the Norwegian Polar Institute, it consists of a 3,300-by-100-metre runway on glacial blue ice on the Antarctic ice sheet. The airport is located at 1,232 metres (4,042 ft) above mean sea level and is 235 kilometres (146 mi) from the coast.
The following outline is provided as an overview of and topical guide to vehicles:
Two-wheel tractor or walking tractor are generic terms understood in the US and in parts of Europe to represent a single-axle tractor, which is a tractor with one axle, self-powered and self-propelled, which can pull and power various farm implements such as a trailer, cultivator or harrow, a plough, or various seeders and harvesters. The operator usually walks behind it or rides the implement being towed. Similar terms are mistakenly applied to the household rotary tiller or power tiller; although these may be wheeled and/or self-propelled, they are not tailored for towing implements. A two-wheeled tractor specializes in pulling any of numerous types of implements, whereas rotary tillers specialize in soil tillage with their dedicated digging tools. This article concerns two-wheeled tractors as distinguished from such tillers.
New Richmond Regional Airport is a large general aviation airport located in the city of New Richmond, Wisconsin, United States. The airport is owned by the City of New Richmond and operated by a seven member airport commission. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2021–2025, in which it is categorized as a local general aviation facility. As of October 1, 2022, the FAA upgraded the classification of the airport and it is now considered a regional airport facility. The State of Wisconsin classifies the airport as a corporate/transport airport.
Vincent A. Weldon is an American aerospace engineer who has designed critical components for both the Apollo Moon missions and the Space Shuttle. In 2006 Weldon called the Boeing 787 Dreamliner unsafe, and Boeing fired Weldon under disputed circumstances.
Boeing South Carolina is an airplane assembly facility built by Boeing in North Charleston, South Carolina, United States. Located on the grounds of the joint-use Charleston Air Force Base and Charleston International Airport, the site is the final assembly and delivery point for the Boeing 787 Dreamliner. Boeing opened the site in July 2011, after purchasing the facilities of suppliers Vought and Global Aeronautica in 2008 and 2009. The final assembly building covers 1,200,000 square feet (110,000 m2) and opened on November 12, 2011. As of September 28, 2017, the site employs 6,943 workers and contractors.
In 2013, the second year of service for the Boeing 787 Dreamliner, a widebody jet airliner, several of the aircraft suffered from electrical system problems stemming from its lithium-ion batteries. Incidents included two electrical fires, one aboard an All Nippon Airways 787 and another on a Japan Airlines 787; the second fire was found by maintenance workers while the aircraft was parked at Boston's Logan International Airport. The United States Federal Aviation Administration (FAA) ordered a review of the design and manufacture of the Boeing 787 Dreamliner and grounded the entire Boeing 787 fleet, the first such grounding since that of the McDonnell Douglas DC-10 in 1979. The plane has had two major battery thermal runaway events in 52,000 flight hours, neither of which were contained safely; this length of time between failures was substantially less than the 10 million flight hours predicted by Boeing.
An electric vertical take-off and landing (eVTOL) aircraft is a variety of VTOL aircraft that uses electric power to hover, take off, and land vertically. This technology came about thanks to major advances in electric propulsion and the emerging need for new aerial vehicles for urban air mobility that can enable greener and quieter flights. Electric and hybrid propulsion systems (EHPS) have also the potential of lowering the operating costs of aircraft.
