Combine harvester, thresher, invented by Hiram Moore

The combine harvester, or combine, or thresher, is a machine that combines the tasks of harvesting, threshing, and cleaning grain crops. The objective is to complete these three processes, which used to be distinct, in one pass of the machine over a particular part of the field. The waste straw left behind on the field is the remaining dried stems and leaves of the crop with limited nutrients which is either chopped and spread on the field or baled for feed and bedding for livestock. The first combine was invented by Hiram Moore in 1838.
