The Caterpillar Twenty-Two, or CAT 22, is one of the most iconic early models from Caterpillar's impressive range of agricultural and industrial machinery. Introduced in the late 1930s, it was one of the first "small tractors" made by Caterpillar, designed for lighter tasks on farms and small construction jobs. Despite being overshadowed by larger, more powerful tractors that followed in the years to come, the CAT 22 remains a symbol of innovation and reliability, making it a notable piece in the history of heavy machinery.
Introduction to the CAT 22 Tractor
In the era of its introduction, the CAT Twenty-Two was a revolutionary piece of equipment. During the late 1930s, the demand for smaller, more efficient tractors for agricultural work and light construction was increasing. Caterpillar, already an industry leader with its larger tractors, was quick to recognize this need. They designed the CAT 22 to fill the gap between hand-powered farming tools and the larger, more cumbersome tractors typically used for heavier operations.
Manufactured from 1937 until 1957, the CAT 22 was part of Caterpillar’s early attempts to build a compact, versatile machine suitable for use on smaller farms and light-duty projects. Its low weight and relatively modest size compared to other tractors of the era made it ideal for tasks like plowing, grading, and hauling, tasks that were previously difficult to manage with larger machinery.
Design and Specifications of the CAT 22
The CAT 22 was powered by a 4-cylinder gasoline engine, producing approximately 22 horsepower at the flywheel, which is where it earned its name. The tractor had a simple, yet robust design, with many of its components shared with other Caterpillar models of the time, ensuring durability and ease of repair.
Key Features:
The versatility of the CAT 22 made it popular on smaller farms, where larger tractors would have been too much of a burden both in terms of size and cost. With the right attachments, the CAT 22 could be used for a wide range of tasks such as plowing, harrowing, planting, hauling, and even basic grading.
Though it was small compared to its contemporaries, the CAT 22 was a highly effective machine for its intended purpose. It helped farmers and small construction crews save time, increase productivity, and manage their workloads more efficiently.
Additionally, because of Caterpillar’s reputation for durability, the CAT 22 was trusted by farmers, particularly those in more rural or remote areas where equipment downtime could mean severe loss in productivity.
The Impact of the CAT 22 on the Industry
The introduction of the CAT 22 marked a pivotal point in the development of agricultural and construction machinery. It demonstrated Caterpillar's ability to respond to market needs, expanding from large construction machinery to include more compact, specialized equipment for niche markets like farming. This innovation set the stage for future small tractor models in the Caterpillar line-up.
Although the CAT 22 was eventually replaced by larger, more powerful models like the CAT D2 and D4, it was an important predecessor. It bridged the gap between hand tools and large-scale machinery and provided a foundation for the advancement of tractor technology.
Legacy and Collectibility
Today, the CAT 22 is considered a collector’s item. Vintage machinery enthusiasts and collectors value the model for its historical significance, ruggedness, and the role it played in shaping the agricultural and construction equipment industries. Restoring and maintaining a CAT 22 is a challenging but rewarding task, with many enthusiasts taking pride in keeping these historic machines running.
It is not uncommon to see CAT 22 tractors at vintage equipment shows, where they are often admired for their engineering simplicity and longevity. For those interested in vintage equipment, restoring a CAT 22 can offer a deep dive into the past, allowing enthusiasts to experience firsthand what working with one of these classic machines was like.
Challenges with Maintaining the CAT 22
Like all vintage equipment, maintaining and restoring a CAT 22 can present challenges. Parts for the CAT 22 can be difficult to find due to its age, and those that are available are often expensive. However, many parts from later models of Caterpillar equipment are compatible with the CAT 22, making repairs and replacements somewhat easier.
Owners of the CAT 22 must also deal with its simple yet effective engine and mechanical systems. While these components are robust, they are not as efficient or powerful as modern engines, and ensuring that the engine and transmission are in good working condition requires a solid understanding of older mechanical systems.
Conclusion
The CAT 22 remains an important piece of Caterpillar's legacy, representing a key step in the evolution of agricultural and light construction equipment. Its simplicity, reliability, and versatility made it a trusted machine for small-scale operators during the mid-20th century, and its historical significance continues to be celebrated today by collectors and machinery enthusiasts. The story of the CAT 22 is a testament to Caterpillar’s forward-thinking approach to meeting the needs of farmers and operators in a rapidly changing world.
By looking back at the design and success of the CAT 22, we gain insight into the roots of modern construction and agricultural machinery, illustrating how far the industry has come while still honoring the machines that laid the groundwork for today's technologies.

The tractor had a simple, yet robust design, with many of its components shared with other Caterpillar models of the time, ensuring durability and ease of repair.
Key Features:
- Engine: The CAT 22 was powered by a 4-cylinder, 2.2-liter gasoline engine. While modest by today’s standards, it was sufficient for the tasks it was intended to handle, offering a combination of reliability and efficiency for small farm operations.
- Transmission: The transmission was a mechanical, constant mesh type with 4 forward speeds and 1 reverse, providing versatility in different field conditions.
- Track System: Much like other Caterpillar machines of the era, the CAT 22 used a continuous rubber track system instead of wheels, making it much more stable on soft or uneven terrain. This was particularly important for farming, where the ground conditions could vary significantly.
- Size and Weight: The CAT 22 was compact for its time, weighing around 5,000 pounds. It was light enough to be used on smaller plots of land but still offered substantial power for various tasks.
- Steering: It utilized a unique "differential steering" system, where turning was achieved by varying the speed of the tracks, rather than using a traditional steering wheel. This provided excellent maneuverability in tight spaces, such as around farm buildings or on narrow lanes.
- Hydraulics: The early versions of the CAT 22 did not feature the advanced hydraulics we associate with modern tractors. However, later models incorporated simple hydraulic systems for improved implement control.
