The IH International Harvester McCormick B250 and B275 tractors were iconic workhorses in the agricultural world, known for their robust build, reliable performance, and versatile capabilities. Introduced in the late 1960s, these tractors were part of the "B" series, designed to replace the earlier "Super A" and "Super C" lines. Both models were powered by International Harvester's own diesel engines, the B250 featuring the 3.9-liter D-239 and the B275 utilizing a larger 4.1-liter D-242. These engines delivered impressive torque, making them ideal for challenging tasks like plowing, tilling, and heavy hauling. The B250 generated approximately 54 horsepower, while the slightly larger B275 boasted roughly 65 horsepower. Both models offered a variety of transmission options, including a standard 4-speed manual with an optional 2-speed rear axle and a more advanced 6-speed synchromesh transmission for smoother shifts. The B250 and B275 were also renowned for their robust construction. Their cast iron frames were designed to withstand years of demanding operation in tough agricultural environments. Both models featured a live hydraulic system, which provided power to implements and allowed for the use of various attachments. The cabs were spacious and well-designed, offering improved comfort and visibility for the operator. The B250 and B275 played a vital role in transforming the agricultural industry, helping farmers increase productivity and efficiency. Their reputation for durability, power, and versatility made them a popular choice for farms and ranches throughout the United States and beyond. While production ceased in the late 1970s, these tractors continue to be celebrated for their enduring legacy and practical value.
