This design thus eliminated the need for drive belts to power the tractor forward or backwards. The only belts required on Gravely equipment (with the exception of the 408) is the blade drive belt for its mower decks, which is powered by a gear box on the deck, which receives power from a PTO driveshaft connected to the tractor's drivetrain.
The main parts of a cylinder or reel mower are: Blade reel/cylinder: Consists of numerous (3 to 7) helical blades that are attached to a rotating shaft. The blades rotate, creating a scissor-like cutting motion against the bed knife. Bed knife: The stationary cutting mechanism of a cylinder/reel mower. This is a fixed horizontal blade that is ...
Four wool spinning machines driven by belts from an overhead lineshaft (Leipzig, Germany, circa 1925) The belt drives of the Mueller Mill, model and reality, in motionA line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century.
Reel mower. Reel mowers, also called cylinder mowers [2] (familiar as the hand-pushed or self-powered cylinder lawn mower), have a horizontally rotating cylindrical reel composed of helical blades, each of which in turn runs past a horizontal cutter-bar, producing a continuous scissor action. The bar is held at an adjustable level just above ...
Threaded tape of an open Compact Cassette in the tape drive. The capstan is a rotating spindle used to move recording tape through the mechanism of a tape recorder.The tape is threaded between the capstan and one or more rubber-covered wheels, called pinch rollers, which press against the capstan, thus providing friction necessary for the capstan to pull the tape.
To prepare for use, the supply reel (or feed reel) containing the tape is placed on a spindle or hub. The end of the tape is manually pulled from the reel, threaded through mechanical guides and over a tape head assembly, and attached by friction to the hub of the second, initially empty takeup reel.
The centrepin reel (or centerpin, center pin, or float reel) is a single-action reel which runs freely enough on its axle ("centrepin"). The centrepin reel is the earliest fishing reel design invented by humans, and is historically and currently used for coarse fishing. Instead of a mechanical drag, the angler's thumb is typically used to ...
The St. Louis Southwestern Railway of Texas (reporting mark SSW), operated the lines of its parent company, the St. Louis Southwestern Railway within the state of Texas. The St. Louis Southwestern, known by its nickname of "The Cotton Belt Route" or simply the Cotton Belt, was organized on January 12, 1891, although it had its origins in a rail line founded in 1871 in Tyler, Texas that ...
