The Eagle '6-A' tractor owned by Richard 'Dick' Grimm, Charlotte, Iowa will be 'Featured Tractor' at the 1989 Old Threshers Reunion in Mt. Pleasant, Iowa. It was purchased from Daniel Pelnar, Two Rivers, Wisconsin in 1983 over the telephone and restored in 1988.

The Eagle '6A' tractor was built in Appleton, Wisconsin by the Eagle Manufacturing Company. It was tested by Nebraska Test October 21-November 1, 1930, closing out the Nebraska Tests for the 1930 testing season. It was given a 22-37 rating under A.S.A.E. and S.A.E. test codes.

A Hercules 6-cylinder vertical, L-head engine was featured. Rated at 1416 rpm, it carried a 4x41/2' bore and stroke. Standard items were a U6 magneto and a Zenith 96ATO carburetor. This tractor weighed approximately 5500 pounds and was powered by a gasoline engine. Up until this time, the Eagle tractor was powered by a 2-cylinder engine. Contrary to belief that this tractor was related to the Allis Chalmers, I truly believe that this is fiction, not fact in any way.

Prior to the Eagle 6 that is on display for the 1989 season in the Old Threshers Heritage Museum, the company made a tractor in 1906 which used an opposed 2-cylinder engine. In 1911, an Eagle 56 horsepower model was introduced with a 4-cylinder engine with an 8' bore and 8' stroke that operated at 425 rpm with a drawbar rating of 45 horsepower. In 1916, two Eagle tractors were offered-an 8-16 and a 16-30. The Eagle 16-30 was offered from 1916 to 1932. From 1917 to 1924, the 12-20 and the 12-22 were in production. It was also a 2-cylinder, 7'x8' engine. From 1925 to 1928, 2-cylinder tractors were very popular, as was the Eagle.

The last two Eagle heavyweight models were the 20-36 'E' and the 20-40 'H'. Both were equipped with 2-cylinder engines of 8' bore, but the 'E' had a 9' stroke and the 'H' traveled 10'. The model 'E' was listed from 1929-1934, and the 20-40 'H' went from 1926-1938. The Eagle went from 2-cylinder to 6-cylinder in the new Eagle '6-A' tested in Nebraska in 1930. Directories for a 1934 show a Waukesha 4'x43/4' engine. The Eagle Company suspended production of tractors during World War II and apparently did not resume manufacture after the war.
