Cyrus McCormick's Farm (Walnut Grove)
Cyrus H. McCormick, inventor of the first practical grain reaper, was born on this farm in 1809. He successfully demonstrated the reaper in a nearby field in 1831 and patented the machine in 1834. The site includes the McCormick house (1822); the log workshop where the first reaper was built, with a replica of the reaper; a log gristmill; and a smokehouse. McCormick's descendants donated the farm to Virginia Tech in 1954, which in 1956 established the Shenandoah Valley Agricultural Research and Extension Center here.
