Eagle Engines
   

The Eagle Company first started experimenting with gas engines in 1899. The final design was a conventional single cylinder, side shaft and water cooled engine that was first marketed in 1900. These first engines were built in 10 different horsepower sizes, ranging in size from 1 1/2 hp. to 20 hp.

The second phase of engines with a new design began in 1908. This new design featured the familiar 2 cylinder engine that would become the Eagle trademark. Sizes ranged from 12 hp. to 30 hp. These were heavy built engines, the cranshaft was set so that both pistons travelled side by side, thus as one cylinder was exhausting, the other was coming up on compression. This arrangement produced the distinctive "Eagle Beat". My grand daughter calls my Eagle the "polka-polka" tractor because of the sound.

When the new tractor designes appeared in 1913, Eagle engineers concentrated their efforts into building tractors and not engines. Throughout the 1920's, Eagle offered portable and skid engines patterned after the engines used in the model H Eagle tractors. Sizes offered were 25, 30, and 40 hp.

Any Eagle stationary, skid, or portable engine is a scarce item, especially the early ones.

1900-1908
15 hp. single cylinder
These engines ranged in size from 1 1/2 hp. to 20 hp. They were high quaility with extra heavy flywheels which added to balance and easy starting. The 1 1/2 hp. weighed 250 lbs. and the 20 hp model weighed in at a whooping 5300 lbs. The larger sizes were cooled by an evaporation screen tower.
 
1908-1916?
8 hp. single cylinder
These models could come in either a skid mounted, or truck mounted. These engines came with the removable valve cages that would become an Eagle trait. All these models were of the 2 cylinder design except for the smallest size, the 8 hp. model. Other sizes ranged from 12-30 hp.
 
1922-1930
Model H series tractor engine, skid mounted
These power plants were simply the same engines that were put into the model H tractors. All 2 cylinders with 25, 30, or 40 hp. The pickering governor made them a good choice for where steady, reliable power was needed. Could be had in skid or truck mounted.
