Agricultural machinery : ウィキペディア英語版
Agricultural machinery

Agricultural machinery is machinery used in the operation of an agricultural area or farm.
== History of the Machines ==

===The Industrial Revolution===
With the coming of the Industrial Revolution and the development of more complicated machines, farming methods took a great leap forward.〔(Agricultural engineering ) Britannica Online. 〕 Instead of harvesting grain by hand with a sharp blade, wheeled machines cut a continuous swath. Instead of threshing the grain by beating it with sticks, threshing machines separated the seeds from the heads and stalks. The first tractors appeared in the late 19th century. 〔(Tractor (vehicle) ) Britannica Online. 〕
