The Allis Chalmers D21 Series 2 tractor was a workhorse of the agricultural industry, known for its durability and reliability. Introduced in 1962, the D21 Series 2 was a significant upgrade over its predecessor, featuring a more powerful engine and improved transmission. It was powered by a 4-cylinder, naturally aspirated diesel engine that delivered a robust 61 horsepower, making it suitable for a wide range of farm tasks, from plowing and cultivating to hauling and harvesting. The tractor's robust design included a heavy-duty frame, a live rear axle with a differential lock, and a hydraulic system capable of powering various implements. The D21 Series 2 also boasted a comfortable operator station with a spacious cab, adjustable steering wheel, and easy-to-reach controls.

The Allis Chalmers D21 Series 2 was highly regarded for its versatility and efficiency. It offered a wide range of transmission options, including a standard 6-speed gearbox, a 12-speed gearbox, and a creeper gear option for precise low-speed operations. This versatility, combined with its powerful engine and reliable construction, made the D21 Series 2 a popular choice for farmers seeking a durable and capable tractor for their operations. The D21 Series 2 remained in production until 1971, leaving a lasting legacy as a dependable and capable workhorse. While it has been discontinued for many years, the D21 Series 2 continues to be cherished by enthusiasts and collectors who appreciate its historical significance and enduring performance.
