Haying Machines
In 1822, Jeremiah Bailey, of Chester County, Pennsylvania, patented a horse-drawn machine with a revolving wheel with six scythes, used for haying and other cutting.The haying machine was co-developed with the reaper. The basic idea in the reaper, the cutter-bar, became part of mower. Hazard Knowles, an employee of the Patent Office, invented the hinged cutter-bar, which could be lifted over an obstruction, but never patented the invention.
In 1844, William Ketchum of Buffalo, New York patented the first machine intended to cut hay only, and dozens of others followed. An improved mowing machine was patented by Lewis Miller of Canton, Ohio, in 1858.
Hayrakes and Tedders
Hayrakes and tedders seem to have developed almost of themselves. Diligent research has failed to discover any reliable information on the invention of the hayrake, though a horserake was patented as early as 1818. Joab Center of Hudson, New York, patented a machine for turning and spreading hay in 1834. Mechanical hayloaders have greatly reduced the amount of human labor. The hay-press makes storage and transportation easier and cheaper.
Binders
Binders cut and bind corn. An addition shocks the corn and deposits it upon the ground. The shredder and husker removes the ears, husks them, and shreds shucks, stalks, and fodder. Power shellers separate grain and cobs more than a hundred times as rapidly as a pair of human hands could do.
