The RC was a general purpose tractor designed to compete with International Harvester's Farmall. Powered by a four-cylinder Waukesha engine it produced 17hp at the belt. It also had a three-speed transmission and the unusual "chicken roost" steering arm.

THE INTERNATIONAL HARVESTER FARMALL

The Farmall was the first all-purpose tractor made by International Harvester. Produced from 1924 to 1932, it could pull plows and cultivate crops. On many farms it would be a tricycle row crop Farmall that replaced the horse and set the style of tractors for years to come.With the introduction of the Farmall 20 the original Farmall came to be referred to as the "Regular".

THE ALLIS-CHALMERS MODEL U

In 1847, Edward P. Allis started a company in New York that sold millstones and water wheels. In 1869, they went into building steam power engines and pumps. Then in 1901, Edward P. Allis & Company merged with Fraser and Chalmers along with the Gates Iron Works to form Allis-Chalmers. The company moved to Wisconsin and there, in 1914, they built their first tractor but it wasn't until the introduction of the 15-30 in 1918 that the company had a really successful tractor. In 1928, A-C aquired the Monarch Tractor Company; in 1931, Advance-Rumely of LaPorte, Indiana; in 1953, the Buda Engine Company of Harvey, Illinois; in 1955, the Gleaner Harvester Company; and in 1959 the French company Vendeuvre. A-C's manufacturing plants became such a landmark in the Milwaukee area that one city even took on the name "West Allis".

In 1929, the company introduced the United tractor which would later be renamed the Model U. The "U" was the first Allis-Chalmers tractor to be painted "Poppy Orange" rather than dark green and was also the first production farm tractor to offer pneumatic tires. Although they were an added expense, pneumatics made for a more comfortable ride and let the tractor be driven at higher speed on roads but most importantly they required about half the power to do field work. Soon all tractor manufacturers would be offering them.

J. I. CASE'S "OLD ABE"

"Old Abe" was the name of the eagle used in the Case trademark. He was a real American Bald Eagle that served as the mascot of Company C of the Eight Wisconsin during the Civil War. He survived 38 battles during the war and for years appeared with his fellow veterans in numerous parades after it had ended.

MASSEY - HARRIS

Both Daniel Massey and Alanson Harris were Canadians who had established successful farm implement companies in the mid 1800s. In 1891, the Massey Manufacturing Company and A. Harris Son & Company Ltd. merged to form Massey-Harris. However it wouldn't be until 1917 that the company began selling tractors. Their first attempt was a marketing agreement for the Bull tractor that ended in failure. In 1919, they formed another agreement, this time with the Parrett Tractor company of Chicago, Parrett went out of business in 1922. M-H tried again in 1928 with the acquisition of J.I. Case Plow Works and the Wallis tractor line. The Wallis was a success and established M-H in the tractor business. In 1953, Massey-Harris merged with Ferguson to become Massey-Ferguson.

Henry Wallis started the Wallis Tractor Company in Cleveland, Ohio in 1912 but he soon moved to Racine, Wisconsin where his firm merged with the J.I. Case Plow Works. Wallis tractors were known for their fuel efficiency and U-shaped steel frame. When Massey-Harris bought the J.I. Case Plow Works Company they sold the Case name back to the J.I. Case Threshing Machine Company. In 1929, the Wallis 12-20 was introduced, it was also sold as the Massey-Harris 12-20, Certified 12-20 and provided the base on which the later Massey-Harris Pacemaker and Challenger tractors would be built.

MINNEAPOLIS-MOLINE

Minneapolis Steel & Machinery Company was formed in 1902, first they built steam engines then later a line of tractors under the Twin City name.

They introduced the Twin City 12/20 in the year 1919, it was a major move by the company toward lighter tractors. It featured unit construction and a novel engine that had four valves per cylinder. Based on the 12/20 concept the 21/32 was introduced in 1929. That same year, M.S.& M merged with the Minneapolis Threshing Machine Company and the Moline Implement Company to form Minneapolis-Moline Power Implement Company.
