A ballast cleaner Matisa C330F in action on the Coastal Railway in Haifa, Israel. A ballast cleaner (also known as an undercutter, a shoulder ballast cleaning machine) is a machine that specialises in cleaning the railway track ballast (gravel, blue stone or other aggregate) of impurities. [1]
The depth and spacing is generally adjustable to accommodate a range of crops and the desired plant density; the degree of adjustability depends upon the chosen seeder. [2] In commercial production, precision seeding is an alternative to placing larger quantities of seed in a row, by dribbling seed or setting several seeds in each position.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
Birdsell believed his machine, which combined the threshing, hulling, and cleaning actions into one process, could reduce the time and energy needed, and therefore increasing the amount of seed a farmer could produce. John C. Birdsell continued to perfect his clover huller, and by 1857 he won first prize at the New York State Fair in Buffalo. [1]
Hand-pushed broadcast spreader. A broadcast seeder, alternately called a broadcaster, broadcast spreader or centrifugal fertilizer spreader (Europe) or "spinner" (UK), is a farm implement commonly used for spreading seed where no row planting is required (mostly for lawns and meadows: grass seeds or wildflower mixes), lime, fertilizer, sand, ice melt, etc., and is an alternative to drop ...
Various machines meter out seeds for sowing in rows. The ones that handle larger seeds tend to be called planters, whereas the ones that handle smaller seeds tend to be called seed drills, grain drills, and seeders (including precision seeders).
The truck weighed 1 short ton (0.91 t) and featured a four-cylinder engine, open cab and chain drive. Its wheels had wooden spokes and rims, while the steel tires were 1.5 inches (38 mm)x5 inches (130 mm) wide. [4] Avery figured farmers could get the most use out of the machines during the harvest season.
A cotton picker at work. The first successful models were introduced in the mid-1940s and each could do the work of 50 hand pickers. Mechanised agriculture or agricultural mechanization is the use of machinery and equipment, ranging from simple and basic hand tools to more sophisticated, motorized equipment and machinery, to perform agricultural operations.
