On August 28, 2018, giants walked the earth at Alvordton, Ohio. On that day, the second biggest Big Bud tractor model, the 12V-92 Detroitpowered 650/50, and the next biggest, a Big Bud 525/50 (see Diesel World January 2018 or go to Dieselworldmag.com), plowed side by side at the Alvordton Plow Days. That was momentous enough, but the 650/50 plowed with the biggest moldboard plow ever made, the 21-bottom DMI plow, built in 1978 to be a show stopper.
The Alvordton-mill Creek Volunteer Fire Department has been putting on the Plow Days since 2009 as a fundraising function. It’s been growing bigger every year, and 2018 put it into the world-class category. In conjunction with Kunkle Farms and Meyer Farms, the Alvordton event is open to tractors about 40 years old. Obviously, that rule was waived in light of the significance of the Big Buds. Depending on Kunkle’s crop rotation, there can be as many as 150 acres of wheat stubble to plow. The real danger this
year was preventing the two monster plows from working up all the ground before the little guys could dip their plowshares.
Back in the January 2018 issue we talked about how the Big Bud tractors came to be. Built in Havre, Montana, they dominated the high-powered tractor market in the late ’70s and early ’80s, if not in volume then by size and power. The 1978 Big Bud 16V-747 was the biggest of those, powered by a massive 16V-92T Detroit rated at 760 horsepower. That was insane horsepower in that era, and while Big Bud was willing to build more of them, only one like it was produced. It remains the biggest ag tractor ever built.
The Series 3 tractors debuted shortly after the 16V-747 and the top dogs among them were the 650/50 and the 665. Both were powered by Detroit 12V-92T V12 diesels. The 650/50 was rated for 650 maximum flywheel horsepower, while the 665 made 665. The significant difference between them was in the chassis, with the 665 having a heavier nose and weighing about 1,000 pounds more. Only two of the 650/50s were configured for agricultural use, the others being set up for construction work. Only six 650/50s, two 665s, and one 650/84 were built. Why so few?
The Series 3 tractors were introduced with a beefy new Twin Disc transmission. Regrettably, those transmissions had teething issues and began dropping like flies. None of the Twin Disc updates fixed them. Twin Disc faced a massive problem, but Big Bud was in worse shape, having built a bunch of pre-sold tractors that sat there waiting for a working transmission—with no fix in sight. This ended up sending Big Bud into Chapter 11 and stopping production. As a result, just that handful of V12 tractors was built.
The day before the August 28 Plow Day, Larry Addleman and Daren Meyers got together for some test-and-tune field work with the two Big Buds. Addleman’s more powerful 650/50 was elected to pull the 21-24 DMI plow, while Meyers’ 1980 525/50 took on the
