Port Huron Farm Tractors

| July 2005

Starting in 1918, Port Huron Engine & Thresher Co. of Port Huron, Mich., began manufacturing Port Huron 12-25 tractors, weighing 5,700 pounds and using an Erd 4-by-6-inch bore and stroke, vertical 4-cylinder engine. The tractor was rated to pull three 14-inch plows. It had four wheels, with the pair of rear drive wheels 56 inches in diameter with a 10-inch face. The tractor's weight was listed at 6,200 pounds in 1920, when it sold for $1,700. It used a variable speed friction drive, which provided variable speeds from 1-7/8 to 4 MPH.

Advertisements stated, "The Port Huron Farm Tractor has been designed for use all the year round. By this we mean it has been designed for belt power as well as drawbar service. All gears are enclosed and run in a bath of oil." It was specially designed to burn kerosene, the advertisement added. Tractor production ended in 1922.
