Allis-Chalmers Model 6-12

Tractors had not yet managed to completely replace the horse team for all farm tasks.

The product category of row-crop tractors as we know them today had not yet been developed, and the Allis 6-12 had a very attractive value proposition.

Unfortunately that proposition was also suspiciously similar to that of the Moline Universal tractor, which had been on the market for about 2 years before the Allis 6-12 appeared.

Two-wheel tractors would continue to have a place in agriculture both in the U.S. and around the world, but they would no longer compete in the same market segment as the larger four-wheel row-crop designs.

However, the Allis-Chalmers Model G, introduced two decades later, was an interesting design that in some respects echoed the concept of the 6-12, albeit now "facing the other way", with the implement leading and the motorized drive unit now pushing rather than pulling.
