The Allis Chalmers Model 210, 220, and D21 tractors were versatile workhorses designed for a variety of agricultural tasks. These tractors, built by Allis Chalmers Manufacturing Company, were renowned for their durability and reliability, becoming popular choices for farmers in the mid-20th century. The Model 210, introduced in 1958, was a compact and maneuverable tractor specifically designed for lighter tasks like cultivating, mowing, and hauling small loads. The Model 220, released in 1959, offered increased power and torque, making it suitable for heavier duties like plowing, discing, and pulling implements. In 1961, the D21 was introduced as a more powerful iteration of the 210, featuring a larger engine and improved hydraulics. All three models shared a robust design, featuring a cast-iron engine block, a simple transmission, and a well-constructed chassis. They were known for their simplicity of operation, making them ideal for both experienced farmers and those new to operating a tractor.

The Allis Chalmers Model 210, 220, and D21 tractors were equipped with various configurations and options to suit different needs. The base model 210 came with a 3-cylinder engine that generated around 30 horsepower. The Model 220 boasted a more powerful 4-cylinder engine, producing approximately 40 horsepower. The D21, an upgraded version of the 210, also utilized a 4-cylinder engine but delivered a slightly higher output of 35 horsepower. All models offered a range of transmission options, typically a manual gearbox with 3 to 5 forward speeds and one reverse gear. They were equipped with a live hydraulic system, allowing for the use of various implements, including plows, cultivators, and loaders. The tractors were available in a variety of configurations, including a standard cab and a versatile canopy-style roof, further enhancing their versatility for different applications. The Allis Chalmers Model 210, 220, and D21 tractors, despite their age, remain valued by collectors and enthusiasts for their historical significance and robust construction.
