Definition of: reaping machine

A machine for harvesting standing grain. It usually consists of a reciprocating cutter resembling that of a mowing machine, a platform or table on which the cut grain falls, and a dropper which is dropped to deposit the bundles of grain. In addition, it often has a reel for bending the grain toward the cutter, or a raking mechanism for pressing the grain down on the table and sweeping it off in bundles, and a binding mechanism. Also called harvester.
