Harvester - A Historic Landmark Of Agricultural Engineering.
William J. Conroy Of Aylmer, Quebec, Received Patent No. 465,127 On
The First Field Hay Chopper On 15 December, 1891. Its Sickle Cut
The Crop, Which Was Elevated Directly Into A Cylindrical Curved-Bar
Cutterhead. It Was Not Commercially Successful, But It Recognized
The Need. Professor Floyd Waldo Duffee, Agricultural Engineering
Department, University Of Wisconsin, Built And Field Tested A Silo
Filler With An Attached Hay Loader In 1926. He Presented The
Specifications Of A Complete Unified Harvester To The National
Asabe Meeting In 1927. The J. I. Case Company Built A Field Machine
For Duffee, Which He Tested And Improved Until 1930. Mr. Erwin W.
Saiberlich, Chief Engineer Of The Fox River Tractor Co., Appleton,
Wisconsin, Had Also Put Together Such A Machine. At Duffee's Urging
Saiberlich Built His First Harvester In 1931, Which He Improved And
Sold In 1932. He Redesigned The Machine During The Great Depression
And Fox Began Selling It In 1936. His Design Was So Fundamentally
Correct In Principle That All The Machines Built 50 Years Later
Were Still Very Similar. More Than 600,000 Such Harvesters Had Been
Built By 1986. This Development, Which Significantly Reduced The
Cost And Labor To Harvest, Store And Feed Forage, Is Hereby
Dedicated By The American Society Of Agricultural Engineers
