Elec-Trak
The GE Elec-Trak was the first commercially produced all-electric garden tractor, made mostly between 1969 and 1975 at GE's Outdoor Power Equipment Operation under Bruce R. Laumeister. Despite their limited production and availability, many Elec-Traks are still in use today and have a cult following among tractor and electric vehicle enthusiasts. They are an archetypal or seminal design that has influenced all later electric tractors. Several models were produced, including: the E8M and ER8-36 (8 hp equivalent); the E10M (10 hp); the E12 and E12M (12 hp); the E12S and E15 (14 hp); the E16 (an upgraded variant of the E15), and the E20 (16 hp). GE's claimed horsepower figures were notional and inconsistent in documentation and sales literature; the table below includes "real" horsepower. The E8M and ER8-36 were styled more as ride-on mowers than tractors. The "M" suffix used on some models indicates the ability to accommodate a mid-mounted (belly) mower,GE ...

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

Electric Vehicle
An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator). EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft. For road vehicles, together with other emerging automotive technologies such as autonomous driving, connected vehicles and shared mobility, EVs form a future mobility vision called Connected, Autonomous, Shared and Electric (CASE) Mobility. EVs first came into existence in the late 19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time.

Garden Tractor
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] |
Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) 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 (and originally) 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. Etymology The word ''tractor'' was taken from Latin, being the agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term " traction motor" (1859). National variations In the UK, Ireland, Australia, India, Spain, Argentina, Slovenia, Serbia, Croatia, the Netherlands, and Germany, the word "tractor" u ...

NEMA Connector
NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association. NEMA wiring devices are made in current ratings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of contact blade widths, shapes, orientations, and dimensions create non-interchangeable connectors that are unique for each combination of voltage, electric current carrying capacity, and grounding system. NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (''CSA C22.2 No. 42''), Mexico (''NMX-J-163-ANCE'') and Japan (''JIS C 8303''). Other plug and receptacle types are for special purposes or for heavy-duty app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anderson Powerpole
The Anderson Powerpole is a family of electrical connectors by Anderson Power Products (APP), although plug compatible connectors are now available from alternate sources. Specific variants of this series of connectors have become de facto standards for conveying "higher power" direct current (DC) electrical power, although these standards are inconsistent and sometimes ignored. Overview Powerpole connectors are physically and electrically hermaphroditic, thus avoiding the need to worry about which end is the plug and which the socket, or which end has the correct polarity. This is in contrast to the physically—but not electrically—hermaphroditic two-wire trailer plug. Powerpole connectors are available with current ratings up to 180 amperes. The 15/30/45 ampere-rated connectors are the most common, using the same plastic housing and differing only in the metal contact inserted into the housing. The contact is selected based on the ampacity and wire gauge. The colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel Horse
Wheel Horse was a manufacturer of outdoor and garden power equipment, including lawn and garden tractors. The company's headquarters were in South Bend, Indiana, USA. History The business was started in the two-car garage of Elmer Pond in 1946. Pond began building two-wheel, self-propelled "Walk-Away" garden tractors that were sold under the Pond name. Due to a naming conflict with another company, the company's name was changed to Wheel Horse. The name not only evokes tractors generally (doing tractive work with wheels) but also the connotation of a steady, dependable worker (wheelhorse). Pond's son Cecil Elwood Pond continued to develop and market the company's products. The framework was typically simple angle or channel iron and various surplus motorcycle and automotive parts were used. In 1947, a four-wheel tractor, the "Ride-Away" model was introduced for garden use. It was also made from crude parts and without a hood for easy service access. The demand for garden ...

Gardening Tools
A garden tool is any one of many tools made for gardening and landscaping, which overlap with the range of tools made for agriculture and horticulture. Garden tools can be divided into hand tools and power tools. Hand tools Today's garden tools originated with the earliest agricultural implements used by humans. Examples include the hatchet, axe, sickle, scythe, pitchfork, spade, shovel, trowel, hoe, fork, and rake. In some places, the machete is common. The earliest tools were made variously of wood, flint, metal, tin, and bone. The development of metalworking, first in copper and later in bronze, iron, and steel, produced today's durable tools, including such efficient cutting tools as pruning shears (secateurs – for example anvil pruners), grass shears, and loppers. Increasing use of modern alloys allows many tools to be made both stronger and lighter, making them more durable and easier to use.
