Mack M100SX resurgence, being the biggest Mack truck ever constructed. Simultaneously, Welker Farms in Montana has been working on a 1977 Big Bud KT-450, transforming it into a custom Big Bud 700—one of the largest tractors ever produced. It is now completed and is proving its worth during the wheat harvest on the 10,000-acre farm.
Notice that I referred to it as “one of the largest” instead of simply “the largest.” The title of “the largest” belongs to the Big Bud 747, which is powered by a Detroit Diesel 16V71, stands 14 feet tall, and measures 25 feet wide. Nevertheless, the latest Big Bud from Welker Farms (which has three) is incredibly robust, weighing around 52,000 pounds when fueled and without any ballast. It is equipped with a 700-horsepower Cummins KTTA engine, replacing the original 19-liter diesel with a compound-turbo unit of the same size, and it features an Allison 6000 Series transmission.
The Big Bud is equipped with 75,000-pound Caterpillar axles, accompanied by custom Wold wheels fitted with massive Titan 1400 LSW tires. These tires are so large that the tractor’s original fenders had to be modified for accommodation. Expectably, this equipment has undergone significant customization, as new-old stock parts for a low-volume tractor produced in Montana during the 1970s are scarce.
Converting the Big Bud from a mere frame to a working tractor took about seven months—and a substantial amount of money. Welker Farms funded $114,700, while sponsors contributed $104,900 in products to facilitate the project. They accumulated a total of 4,000 man-hours on it, and had they hired a shop at $150 per hour for labor, it would have amounted to an additional $600,000. In total, if they contracted a professional shop for the work, it would have cost $820,000.
Creating the largest tractor was never the goal of building this Big Bud 700. Rather, Welker Farms aimed to create a piece of history operational on their land. It also serves the farm well due to its ease of service, unlike many modern machines. Though still gigantic, it causes significantly less soil compaction compared to a 747, and if repairs are needed, they should be much more manageable.
The Comeback of 700HP Beast BIG BUD!!
Currently, three generations are involved in Welker Farms, and it looks like this tractor will be around for a considerable time as well.

**Montana Farm Revives 1977 ‘Big Bud,’ Among the Largest Tractors in Existence, for Wheat Harvest**
In the expansive landscapes of Montana, an incredible restoration initiative has revitalized a segment of agricultural history: the 1977 Big Bud tractor. Celebrated for its remarkable size and power, the Big Bud is esteemed as one of the largest tractors ever manufactured, with its revival standing as a testament to the lasting impact of American farming machinery.
**The Big Bud Heritage**
Initially produced in Havre, Montana, the Big Bud tractor was crafted to fulfill the requisites of large-scale farming operations. With a weight exceeding 50,000 pounds and horsepower ratings surpassing 500, the Big Bud was designed to take on the most challenging agricultural duties, especially within the vast wheat fields of the Northern Plains. Its distinctive design incorporates a broad stance and sizeable tires, enabling it to navigate uneven terrain while reducing soil compaction.
The 1977 variant, in particular, was among the first produced by the Big Bud corporation, founded by the Leland family. The tractor quickly earned a reputation for its reliability and efficacy, becoming a mainstay on numerous farms throughout the Midwest and beyond.
**Restoration Initiatives**
The rejuvenation of the 1977 Big Bud has been a labor of love for a Montana farming family committed to safeguarding agricultural heritage. The project commenced when the tractor was found in disrepair, having remained unused for years. The family acknowledged its historical importance and opted to restore it to its original splendor.
The restoration process required extensive mechanical work, including engine overhauls, transmission rebuilding, and the replacement of worn components. The team also concentrated on cosmetic enhancements, repainting the tractor in its original hues and refurbishing the interior to guarantee it was both functional and aesthetically appealing.
**Modern Agricultural Uses**
Now that the restoration is accomplished, the Big Bud is equipped to handle the challenges of contemporary wheat harvesting. In spite of technological advancements and the emergence of newer, more efficient tractors, the Big Bud remains a formidable machine capable of managing large expanses of land. Its dimensions enable it to tow heavy implements, making it perfect for activities such as tilling, planting, and harvesting.
Farmers who have had the privilege of operating the revamped Big Bud have praised its performance, highlighting its capacity to cover extensive areas in a fraction of the time it would take smaller tractors. The tractor’s substantial horsepower and torque render it especially effective for preparing fields for planting and for harvesting crops.
**Cultural Relevance**
The rehabilitation of the Big Bud also serves as a reminder of Montana’s rich agricultural tradition and the necessity of preserving farming customs. As modern farming methods advance, many older machines are being retired or replaced. Nonetheless, initiatives like this emphasize the significance of maintaining connections to historical roots and honoring the innovations that have influenced the industry.
The Big Bud has emerged as a point of pride for the local community, garnering interest from agricultural enthusiasts, historians, and visitors alike. Its presence in the fields represents not only the technological strides made in the past but also embodies the work ethic and commitment that characterize farming life in Montana.
**Final Thoughts**
The revival of the 1977 Big Bud tractor transcends mere mechanical restoration; it celebrates agricultural heritage and innovation. As it navigates through the wheat fields of Montana, this iconic machinery continues to be an integral part of the farming community, demonstrating that even the largest tractors can leave a lasting imprint on the future of agriculture.
