The Allis Chalmers Model B tractor was a beast of a machine, with a robust powertrain that made it a joy to work with. It produced 18 horsepower from its 4-cylinder engine.

One of the standout features of the Model B was its efficiency. With a top speed of 5 miles per hour, it was perfect for smaller farms or homesteads where precision and control were key.

The Model B's engine was also incredibly reliable, with many owners reporting thousands of hours of trouble-free use.

Key Features

The Allis Chalmers Model B tractor was a game-changer for farmers in its time. Its high-clearance design made it perfect for truck farming, allowing farmers to work in tight spaces.

The Model B's adjustable front axle was a feature that set it apart from other tractors. For $20 extra, farmers could get an adjustable front axle with 10 spacing increments, ranging from 38 to 60 inches.

This high-clearance design was not only practical but also attracted foreign sales, making the Model B one of the first truly international tractor models made.

The Allis-Chalmers Model B was designed with high-clearance in mind, making it a popular choice for farmers who needed to navigate rough terrain.

Farmers could set the front axle for a 43- or 50-inch tread, or opt for an adjustable front axle with 10 spacing increments for $20 extra.

This high-clearance feature was especially useful for truck farmers, who needed to traverse uneven terrain with ease.

The arched front axle and high rear-axle clearance also made the Model B a hit with farmers who worked in areas with frequent flooding or waterlogged soil.

The Model B's high-clearance design even attracted foreign sales, with the tractor being shipped to countries in Europe, Africa, Australia, and South America.

High Power-to-Weight Ratio

The B's high power-to-weight ratio was a major selling point, and for good reason - it was given a high-torque engine that turned out 15½ belt hp.

This power plant was later replaced with an Allis-Chalmers-built 116- and then 125-cubic-inch power plant, which turned out 22¼ hp at the Nebraska Tractor Test in 1943.

That's a significant increase in power, and it's impressive considering the B's weight of just 2,000 pounds.
