Tedder (machine)

History

The tedder came into use in the second half of the nineteenth century.{{cite journal

The action of the tedder is described, in the late 19th and early 20th century, as being used to "stir"{{cite book

Operation

The original tedder is a farm tool on two wheels pulled by a horse; the rotation of the axle drives a gear which operates a "number of arms with wire tines or fingers at the lower ends."{{cite book

In an early, simple hay tedder described in 1852 and manufactured in Edinburgh by the company of Mr. Slight, the two wheels, via a spur wheel and a pinion, drive a set of light wheels, the "rake wheels"; on these two rake wheels are mounted eight rakes, which pick up and disperse the hay.{{cite book

American machines, such as those made by companies such as Garfield, Mudgett, and Bullard (Ezekiel W. Bullard of Barre, Massachusetts, is credited in one source with the invention of the machine, nicknamed "the grasshopper"),{{cite book

Some tedders have the rotating tines enclosed inside a solid structure to increase the force applied to the hay. Other similar machines included the Wuffler and the acrobat. The Wuffler shuffles the hay in a manner similar to the tedder. The acrobat may be used also for turning, and for rowing hay up ready for baling.

Centrifugal rakes

On two opposing horizontal gyroscopes, which are pto-driven, are mounted obliquely downward standing tines. These refer to the green waste and throw it back. Due to the rear-mounted collecting baskets a windrowing is as possible with a Rake. Their distribution is low because of the limited job performance.

Use and importance

Its development was of great importance to agriculture, since it saved labor and thus money:{{cite book
