Eagle Tractors
   

Tractor development started early for this company. The first tractors were built in early 1905, using two of their 16 hp. engine blocks mounted on a opposed configuration crankcase. This was the only model with the opposed set-up.

Then starting in 1910 they developed a 4 cylinder engine to put into their larger tractors. It was a horizontal design similar to the Aultman Taylor tractor of that period.

In 1913 the familiar 2 cylinder style of Eagle tractos appeared on the market. These models were to be the main stay for the company up to 1930, with very few improvements.

1930 was a kind of magical year for change, as with other companies, Eagle was no exception as they introduced their 6 cylinder series of tractors. These 6 cylinder tractors were introduced a bit to late and Eagle could not capture enough of the US tractor market, 1938 was the last year for production of the Eagle tractors.

1905-1906
This tractor was probably rated at 20-32 hp. Weighed in at 12,000 lbs. The side shaft engine used a hit and miss governor. It had a 9.5 in. bore and 13 in. stroke. Very few were built, and after 1906 this model was virtually non existant.  
1910-1916?
The 4 cylinder series was built in 16-30, 25-45, and 40-60 sizes. The 40-60 model weighed in at 19,000 lbs., rear wheels were 72 in. in diameter. The larger tractor sold fairly well in the wheat growing areas of the US.  
1913-1916
The Model D was built in three sizes, 8-16, 12-22, and 16-30. These featured the 2 cylinder headless engine with removable valve cages, with both pistons going forward at the same time which gave a very distinctive sound. This configuration stayed with the 2 cylinder tractors to the end. Grease cups provided lubrication to all engine bearings.  
1916-1922
Model F was only built in two sizes, 12-22, and 16-30. The large shroud around the radiator was done away with. The engine featured an in house built governor. A Madison Kipp oiler was used to lube the pistons.  
1922-1928
The Model H was built in sizes 13-25, 16-30, 20-40, and 22-45. Early “transitional” models still used the old style flywheel governor and chain steering, then later ones went to a Pickering governor and featured automotive type steering.  
1928-1929
Model E was only built in one size, the 20-35. It featured a Madison Kipp oiler for all engine lubrication, radiator set at a conventional position, enclosed transmission, and was the ultimate Eagle two cylinder tractor.  
1930-1937
Model 6A featured a big Hercules 6 cylinder engine. In 1932 they switched to a Waukesha engine. Eagle tractors went from a 2 cylinder engine, to a 6 cylinder starting with this model. Steel wheels or rubber was available.  
1936-1938
Model 6B or Universal used a Hercules 6 cylinder engine. Rubber tires were standard equipment. This little row crop tractor had an adjustable rear tread. Four speed transmission, with speeds to 13 mph.  
1937-1938
Model 6C or Utility shared most of the same specs. as the 6B, only in a standard tread design. This tractor was a handy little rig with a very practical design.
