Ariens entered the lawn and garden market in 1958 with its first riding lawn mower. In 1963 Ariens built and opened a 23,000 square foot manufacturing plant in Brillion, Wisconsin, to ramp up production. In 1977 Ariens built a new metal fabrication plant in Brillion, Wisconsin. Until 1982 Ariens had focused mainly on the residential mower ...
In 1974, the Dixon company coined the term zero-turn radius on their entrance into the mower market. [1] In 2009, the Hustler Zeon became the first fully electric zero-turn mower, with four 12-volt lead acid batteries. As of 2023 most fully electric zero turn mowers use lithium ion batteries ranging from 40 to 80 volts. [2] [3]
In 2004 Gravely produced its last Gravely two-wheeled tractor. As of 2006, Gravely provided a full line of power lawn implements, including zero-turn mowers, reel mowers, and grass trimmers. In 2008, Gravely launched Gravely Turf Equipment, a division geared toward golf courses and turf management nationwide.
Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
A fluid coupling consists of three components, plus the hydraulic fluid: The housing, also known as the shell [5] (which must have an oil-tight seal around the drive shafts), contains the fluid and turbines. Two turbines (fanlike components): One connected to the input shaft; known as the pump or impeller, [5] or primary wheel input turbine. [5]
The affinity laws are useful as they allow the prediction of the head discharge characteristic of a pump or fan from a known characteristic measured at a different speed or impeller diameter. The only requirement is that the two pumps or fans are dynamically similar, that is, the ratios of the fluid forced are the same.
A "reverse" or "inverse" sprinkler would operate by aspirating the surrounding fluid instead. The problem is commonly associated with theoretical physicist Richard Feynman, who mentions it in his bestselling memoirs Surely You're Joking, Mr. Feynman!. The problem did not originate with Feynman, nor did he publish a solution to it.
"First World Problems" is a song by the American parody artist and satirist "Weird Al" Yankovic from his 2014 studio album Mandatory Fun. The song is a pastiche of the music of the Pixies , particularly the songs " Debaser " and "No. 13 Baby".
