Bush Hog
A bush hog or "brush hog" is a type of rotary mower. Typically these mowers attach to the back of a farm tractor using the three-point hitch and are driven via the power take-off (PTO). It has blades that are not rigidly attached to the drive like a lawnmower blade, but are on hinges so if the blade hits a rock or stump, it bounces backward and inward, and then centrifugal force makes it go outwards again. The rotary blades are not sharpened in the same way as a conventional mower blade. They are usually quite dull so they whack through dense plant growth, whereas a sharp blade often gets stuck or slowed. The blades are very heavy, up to an inch thick, so the centrifugal force pulling out is stronger than the forces of the vegetation bouncing in. They are made of heat treated high carbon steel that can withstand strikes with hard objects such as rocks and stones.

High Carbon Steel
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: * no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect; * the specified minimum for copper does not exceed 0.40%; * or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65%; silicon 0.60%; copper 0.60%. The term ''carbon steel'' may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. High carbon steel has many different uses such as milling machines, cutting tools (such as chisels) and high strength wires. These applications require a much finer microstructure, which improves the toughness. Carbon steel is a popular meta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Rams
A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one " hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water. History The Alhambra, built by Nasrid Sultan Ibn al-Ahmar of Granada beginning AD1238, used a hydram to raise water. Through a first reservoir, filled by a channel from the Darro River, water emptied via a large vertical channel into a second reservoir b ...

Draw Bar
A drawbar is a solid coupling between a hauling vehicle and its hauled load. Drawbars are in common use with rail transport, road trailers, both large and small, industrial and recreational, and with agricultural equipment. Agriculture and horse-drawn vehicles Agricultural equipment is hauled by a tractor mounted drawbar. Specialist agricultural tools such as ploughs are attached to specialist drawbars which have functions in addition to transmitting tractive force. This was partly made redundant with Ferguson's development of the 3 point linkage in his famous TE20. A wooden ''drawbar'' extends from the front of a wagon, cart, chariot or other horse-drawn vehicles to between the horses. A steel ''drawbar'' attaches a three-point hitch or other farm implement to a tractor. Road A drawbar is a towing or pushing connection between a tractive vehicle and its load. Light vehicles On light vehicles, the most common coupling is an A-frame drawbar coupled to a 1 7/8 inch or 50 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibson City, Illinois
Gibson City is a city in Ford County, Illinois, United States. The population was 3,407 at the 2010 census. History The site of Gibson City was purchased and platted by Jonathan B. Lott in 1869. In 1870, Lott built a home and a post office there, and several stores and a grain elevator were constructed. Lott named the place ''Gibson'' after the maiden name of his wife, Margaret Gibson Lott, and ''City'' was added later by the post office department. Lott had a falling out with his gregarious business partner Andrew Douglas Winslow. Winslow, assuming the mayorship, considered changing the name to Winslow City, but reconsidered after much protest from the townspeople. Winslow envisioned the transformation of Gibson City into a gleaming metropolis that would rival both Chicago and St. Louis, a vision that has yet to be realized. Eric "Richard" Ryder succeeded Winslow as mayor. Ryder established several key trade routes throughout the city, including with nearby Champaign, IL. Ryder wa ...

Selma, Alabama
Selma is a city in and the county seat of Dallas County, in the Black Belt region of south central Alabama and extending to the west. Located on the banks of the Alabama River, the city has a population of 17,971 as of the 2020 census. About 80% of the population is African-American. Selma was a trading center and market town during the antebellum years of King Cotton in the South. It was also an important armaments-manufacturing and iron shipbuilding center for the Confederacy during the Civil War, surrounded by miles of earthen fortifications. The Confederate forces were defeated during the Battle of Selma, in the final full month of the war. In modern times, the city is best known for the 1960s civil rights movement and the Selma to Montgomery marches, beginning with "Bloody Sunday" in 1965 and ending with 25,000 people entering Montgomery at the end of the last march to press for voting rights. This activism generated national attention for social justice and that summer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vegetation
Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term ''flora'' which refers to species composition. Perhaps the closest synonym is plant community, but ''vegetation'' can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term ''vegetation''. The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality. The contemporary use of ''vegetation'' approximates that of ecologist Frederic Clements' term earth cover, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rock (geology)
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing ro ...
