There are a pair of identical McCormick Deering tractors at the entrance to Wetaskiwin, both seemingly 15-30s as they were the most popular of the three models produced by International Harvester. This is the one on the south side of 50th Avenue.

Highway 2A is the major north-south highway running through Wetaskiwin and 50th Avenue is the major artery leading from it to the downtown area. Near this critical junction were placed a seemingly identical pair of McCormick Deering tractors, reminders of Wetaskiwin's agricultural heritage.

Though these tractors could both be 10-20s, my guess is that they are 15-30s, just judging by the size of the rear wheels. The two look essentially identical (though the 10-20 is somewhat smaller) and both were manufactured from 1923 to 1939. The 22-36, slightly differing in appearance, came later, made from 1929 to 1934.

With a 381.7 cubic inch (6.3 Litre) 4-cyl kerosene burning engine built by International Harvester, the tractor produced 27 horsepower at the drawbar and 35 horsepower at the belt at 1050 RPM, as opposed to claimed power of 15 and 30. International Harvester was pretty conservative with its published numbers, as the 15-30 produced nearly twice the advertised horsepower at the drawbar.

This deluge of power was transferred to the lugged steel wheels through a three speed transmission with one reverse gear. Rear wheels were 50x12 inches while the fronts were 34x6. Top speed in high gear was a slothful 4 MPH. The weight of the tractor was 6000 lbs. as it came off the assembly line.
