the first tractors

President Roosevelt issues an executive order to create the Rural Electrification Administration (REA) in 1935.

the origins of the

mechanized agriculture

In 1993 Irish mechanic Harry Ferguson develops a tractor that incorporates his innovative hydraulic draft control system, which raises and lowers attached implements - such as tillers, mowers ,post hole diggers and plows.

Rural electrification

In 1900 farmers represented 38 percent of the U.S labor force.

First U.S. factory for tractors driven by an internal combustion engine.

Charles Hart and Charles Parr established the first u.s factory devoted to manufacturing a traction engine powered by an internal combustion engine in 1902.

Hydraulic system

propelled combine

Firsts Innovations

Smaller and lighter than its steam-driven predecessors.

Beginning with the internal combustion engine and moving on to rubber tires that kept machinery from sinking in muddy soil, mechanization also improved the farm implements designed for planting, harvesting, and reaping.

1932. Tests by the University of Nebraska Tractor Tests Laboratory find that rubber wheels result in a 25 percent improvement in fuel economy. Rubber wheels also mean smoother, faster driving with less wear and tear on tractor parts and driver.

1938 in Australia. Massey-Harris introduces the first self-propelled combine-- a thresher and reaper in a single machine , net drawn by a tractor or horse.

monitoring systems

the GPS

1966. The DICKEY-john Manufacturing Company introduces electronic monitoring devices for farmers that allow them to plant crops more efficiently.

in 1994, Ushering in the new "precision agriculture," farmers begin using Global Positioning System (GPS) receivers to record precise locations on their farms to determine which areas need particular quantities of water, fertilizer, and pesticides.

Conclusion

Attached to mechanical planters and air seeders, the devices monitor the number and spacing of seeds being planted.

Aerial dusting of crops

The spindle cotton picker

1943 International Harvester builds "Old Red", the first commercially viable mechanical spindle cotton picker, invented and tested by Texans John and Mack Rust beginning in 1927

In 1921U.S. army pilots and Ohio entomologists conduct the first major aerial dusting of crops, spaying arsenate of lead over 6 acres of catalpa trees in Troy to control the sphinx caterpillar

The spindle picker features moistened rotating spindles that grab cotton fibers from open bolls while leaving the plant intact.

A Ronning Harvester

The agriculture has big roots in history and each time get more efficient for can satisfy the needs of the human beings.

in 1918 american Harvester company of Minneapolis begins manufacturing the horse-drawn Ronning Harvester.

The ronning machine uses and improves a harvester developed three years earlier by south Dakota Joseph Weigel.
