The Caterpillar Grader has long been a trusted tool in the construction and mining industries. Whether you’re working on road maintenance, land leveling, or precise grading tasks, these machines stand as a symbol of durability and reliability. For collectors, mechanics, or anyone with a CAT grader in their possession, knowing its exact age and history can be both informative and practical.
This article delves into how one can determine the age of an old Caterpillar grader, specifically focusing on the model with the serial number 8H747. By understanding Caterpillar’s serial number system and the history of the 8H series, we can piece together the context of this grader’s origin, its place in the larger picture of CAT’s legacy, and what that means for current and future owners.
Understanding Caterpillar Serial Numbers
Caterpillar, much like other major heavy equipment manufacturers, uses serial numbers as a unique identifier for each machine. These numbers are much more than just a form of identification; they can provide essential details about the machine, such as its model, year of manufacture, and even specific production details.
For older machines like the CAT 8H747, the serial number system follows a certain format that varies by the era of the equipment. In the case of the CAT 8H series, the number "8H747" is indicative of the machine’s production run within a specific timeframe. Caterpillar used the 8H series of graders primarily during the late 1950s and early 1960s, a period when graders were undergoing significant advancements in terms of engine power, control systems, and overall efficiency.
By analyzing the last digits of the serial number, enthusiasts and experts can pinpoint the exact year the grader was manufactured. Serial number decoding involves a combination of historical knowledge of Caterpillar’s production cycles and cataloged data provided by the company or other authoritative sources like the CAT Service Manual.
The CAT 8H Series Grader
The CAT 8H series is a significant chapter in Caterpillar's history of construction equipment. Manufactured as part of CAT’s commitment to providing highly durable and versatile graders, the 8H series was known for its sturdy construction, powerful engine, and precise grading capabilities.
These machines were often used in road construction, land development, and even some mining applications where accurate surface leveling was required. The introduction of these graders marked a transition from earlier models, with technological improvements in hydraulic systems, operational efficiency, and operator comfort.
The CAT 8H747, with its serial number, is likely to belong to this series, representing a vintage piece of machinery. While these machines are no longer in widespread commercial use, they remain a valuable collector’s item, especially for those interested in the evolution of construction machinery.
How to Determine the Age of Your Grader
In determining the exact age of an old CAT grader like the 8H747, you’ll need to follow a few key steps:
Collecting and restoring old machinery, particularly vintage CAT graders, is more than just a hobby for many enthusiasts. Vintage machines often hold significant historical value and can become a centerpiece for museums or private collections. Furthermore, the restoration of these machines can be a labor of love, providing a glimpse into how construction equipment has evolved over decades.
The CAT 8H747, as a model from the late 1950s to early 1960s, may not be as fast or efficient as modern graders, but it represents a milestone in construction technology. It’s a testament to the craftsmanship and engineering that Caterpillar became known for during this era. For collectors, the restoration of such a machine is an intricate process that requires sourcing original parts, consulting manuals, and sometimes even collaborating with other vintage machinery enthusiasts.
The Role of Graders in Road Construction History
Graders like the 8H747 played an integral role in shaping the landscape of modern construction. The technology behind these machines enabled the precise leveling of roadbeds, which is essential for creating the foundation for asphalt or concrete roads. The importance of this function cannot be overstated, as proper grading ensures the longevity and durability of roads.
Back in the 1950s and 1960s, when the CAT 8H series was in its prime, the need for well-built infrastructure was on the rise. The boom in road construction during the post-war era, especially in North America and Europe, spurred rapid technological innovation in equipment like graders, bulldozers, and scrapers. These innovations helped pave the way for the highways and roads we rely on today.
Final Thoughts: The Enduring Legacy of the CAT 8H747
The CAT 8H747 grader, though old by today’s standards, is more than just a machine—it’s a link to the history of construction equipment. For those fortunate enough to own or restore one of these vintage graders, it offers a unique opportunity to appreciate the history of construction machinery and to keep the legacy of the Caterpillar brand alive.
Whether you’re in the market for a collector’s piece, a restoration project, or simply have an interest in the history of graders, understanding the age and significance of the 8H747 is an essential step in preserving this iconic piece of heavy equipment. By respecting its history and continuing to share stories about these machines, we keep the past alive for future generations of builders and equipment lovers.

- Check the Serial Number: As mentioned earlier, the serial number is the most direct way to pinpoint the manufacturing year. For CAT graders, the first digits of the serial number typically indicate the model series, and the following digits correspond to the production sequence. For example, the serial number "8H747" suggests that it is part of the 8H series.
- Consult the Caterpillar Production Data: Caterpillar maintains extensive production records for its equipment. By referencing the serial number, it is possible to determine the exact production year of your grader. These records can sometimes be found through dealers, official service manuals, or online databases specifically dedicated to heavy equipment history.
- Research Historical Data and Sources: There are several online communities and forums that specialize in vintage machinery. Often, members of these forums will have the precise manufacturing dates or an intuitive understanding of the serial number system. Some websites even offer tools to decode serial numbers for Caterpillar and other manufacturers.
- Inspect the Machine for Model-Specific Features: Even though knowing the serial number is key, examining other elements of the grader such as the engine model, tire type, and hydraulic systems can offer additional clues about its era. Early models may lack the more advanced features seen in later models, providing a rough estimate of the grader's age.
