Utility Tractors

International Harvester Company (IHC) with its McCormick Deering division along with the J.I. Case were the pioneers of the utility tractor commonly referred to as Standard Tread Tractor or Industrial tractor.
From almost the very beginning, Tractor companies had a knack for getting the most from its tractors. Early Case steam Road Rollers were a classic example of an adaptation of existing machinery to the Construction Equipment market.

These machines provided a profitable sideline for Tractor companies due to the fact that engineering and production costs were lower than building an entirely new machine.

In the early 1920's Intentional Harvester Company began to explore the potential for a simpler brand of utility tractor. Standard tread tractors were useful for far more than simply plowing; the company merely needed to get the tractors into the right location.
Rather than complex conversions, a utility tractor could be created with little more than a paint job a new set of stickers and wheels and possibly a different seat Despite the simplicity of creating a industrial tractor, getting into the industrial market was an entirely different matter.

With tractor dealers in location that served the farmer most all dealers couldn’t support expanding into industrial tractor sales or later into construction equipment sales For decades sales and distribution of the utility tractors would be a obstacle that hindered tractor companies from expanding into the construction equipment industry.
 Despite the challenges IHC With a concentrated effort of advertisements and sales people, put its tractors to work on an incredibly diverse range of jobs.

The Birth of the Utility Tractor
The first utility tractor adapted for industrial use was the 1922 McCormick-Deering 10-20 The tractors were simply 10-20s with the serial numbers indistinguishable from other McCormick-Deering 10-20s. 1923 the McCormick-Deering 10-20 sold to industries was designated the Model 20. Cast iron disc wheels were used front and rear A foot accelerator, suspended front end, high-back seat, Down mount muffler, dual rear tires, and rear-wheel brakes were added in 1924. Development continued for 1925, and highspeed (10.4 miles per hour!) top gear and transverse leaf front suspension were added. Front and rear bumpers and an assortment of wheel lugs were added as options.
Sales for 1925 are listed as "several hundred" and The company responded to the demand by adding an "IND" suffix to the serial number in 1925. In 1926, production of Model 20s reached 1,400 units, and the Model 20 was assigned unique serial numbers that began at 501 and were coded "IN."
  Case Utility Tractors

Cases President Leon Clausen felt strongly about the industrial marketplace for Case equipment and repeatedly stressed the importance of industrial applications of farm tractors. On April 14, 1928, a newly released Model L was equipped with a crawler unit. Following extensive tests, Model L and smaller Model C industrial tractors were soon in production. In February 1929, Clausen required engineering to provide a high road speed for LI tractors to be used in California.
These units had a spring in the front axle because of the the hard rubber tires and the high gear speed used for road work. A seat backrest was provided as standard equipment for Model LI tractors and a foot throttle was standard. Since the cast wheels were heavy enough, agricultural wheel weights were not needed. In a June 6, 1930, memo to engineering, Clausen asked that the following be added to Model LI units:
• Provision for a 5th wheel to pull trailers.
• Rear wheels with expanding ring rims to make tire changing easier.
• Heavier rear wheels to avoid bolting on agricultural-type weights.
• A pulling point for chains to be built in, front and
• Provision for extension rims to be added for more traction.
• Arrangements for crawler track applications to take the side thrust of grader blades.
• Heavier front axles to take the weight of cranes, shovels and excavating equipment.
• The addition of a very low and very high gear speed. In 1930, a Bates track conversion was also tested. A Trackson unit soon followed
Construction Equipment revolution

As the Standard type utility tractor matured so did its versatility. companies began marketing various "push-pull" implements, like dozer and scraper blades, If these tractors could move dirt and stone, they could handle other materials as well; if they could push and pull, they could lift; too The advantages were so great that sales started to climb.

There's little doubt Case's successful Industrial Tractor was the reason Case was choose to supply tractors to the military during World War II.In a time of government restricted production of new tractors Case produced more than 15,000 for military use.

 Allis Chalmers announced the Model IB tractor in the 1939, early sales literature for the "IB" Allis-Chalmers noted that it "drives like a car as it has similar controls with a foot controlled throttle, clutch, and brake. In addition there are individual hand brakes on each rear wheel." The low, compact construction of the IB industrial tractor made it ideal for work in small, cramped areas. It used the same four-cylinder, 3% x 31/2 inch engine as the general purpose Allis-Chalmers B tractor.

McCormick Deering

McCormick Deering 10-20 This was the International Tractor that followed the McCormick Deering Titan. It came out in 1923 and was discontinued in 1939. A total of 219,000 were made and the peak production year was 1929. It was slow and cumbersome, but was excellent for plowing as well as on the belt. It carried the same four cylinder engine as the "Regular Farmall" introduced that same Year by International Harvester Company. In 1923, the 10-20 was listed at $785; the 15-30 at $1250. By 1939, the 10-20 was listed at $950 with steel lugs, and $1158 with rubber tires.

Farmall Tractors
International Harvester Company built 135,000 regular Farmall Tractors between 1923 and 1932, when the name was changed to "F-20." (The F- 12 was also introduced in 1932 by IInternational Harvester and 132,000 F-12's were built between 1932 and 1938.)
