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.

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.  
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.  
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.  
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.  
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.  
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.  
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.  
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.  
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.
