International
Harvester
 |
A Tractor
Company is born
In 1902 after months of negotiations J.P. Morgan and Company purchased both the
McCormick Harvesting
Machine Company. and the Deering
Harvester Company., along with two smaller harvester companies. Thus the
International Harvester Company was
created. |
International Harvester began building gasoline tractors in 1906, making them the first company in the small
tractor business. The earliest
lightwieght International Harvester tractors had a friction drive system which gave the tractor a 15 belt
horsepower rating.
Two Tractor
lines one
company.
In 1908 International Harvester introduced the Titan model that was sold by Deering dealers and produced at the companies Milwaukee, WI plant. The company’s Mogul line that followed in 1910 was manufactured at the Chicago plant and sold by McCormick dealers. Because of Antitrust regulations that resulted from the 1902 merger International Harvester had to operate several separate entities within its corporation for a few years.

The International
Harvester’s Mogul 8-16
tractor began rolling
out of the Chicago
factory in 1914. The
Mogul 8-16 was a simple
and easy to operate
single-cylinder tractor
that was also easy to
maintain and repair. Its
price was affordable and
it became very popular. |

Optional PTO |
|
In 1919, IHC began experimenting with PTO-equipped International 8-16s, and in 1921, the PTO
became available as special order equipment on the International 15-30. The new
McCormick-Deering 10-20 and 15-30 also appeared in 1921, and the PTO was available on
both machines. The Farmall used a PTO as early as 1922, and it became an integral part
of the tractor's design.The next hurdle was standardization of PTO shaft rotation speeds,
coupling size, and splining. Under the auspices of the American Society of Agricultural Engineering
(ASAE), representatives from tractor manufacturing companies met to attempt to standardize the PTO
coupling so that tractors and implements from different manufacturers would be interchangeable.
It took about five years to become reality, but by 1931 ASAE had mediated a standard for the PTO
and it was being applied to any imaginable implement. The PTO continued to develop with tractors,
eventually shaking out 540

The first Farmall tractor with an optional diesel engine is the M. It started
