World's Largest Farm Tractor
They're calling it the world's largest, most powerful and tallest farm tractor. It's the 750 hp "Big Bud", custom built by Northern Mfg., Havre, Mont., for Elmer and Melvin Rossi, of the 20,000 acre Rossi Brothers Farm, located near Bakersfield, Calif.
The 100,000 lb. monster is powered by a 16V-92T Detroit 16 cylinder turbo-charged diesel. Although the engine as installed is rated at 750 hp, later models may be applied at up to 880 hp from the turbocharged and aftercooled configuration of the 16 cylinder engine. B. H. Goodsite, of Detroit Diesel Allison, a division of General Motors, told FARM SHOW. The 750 engine powering the giant tractor develops maximum power at 2,100 rpm. Torque reaches a peak of 2,408 pound ft. at 1,400 rpm, according to Goodsite.
Believed to be the tallest tractor ever built for farm use, it stands 15 ft. tall and 20 ft. wide. Its tires are 8 ft. in dia.
The tractor's accessories include a mini-computer to calculate tractor efficiency, such as pto speed, battery voltage, true ground speed, acres worked per hour and distance traveled. It's also equipped with a closed-circuit TV screen and camera so the operator can watch implements work, an AM-FM stereo, a CB radio and an automatic transmission. Other accessories include a refrigerator, air conditioning, hydraulic suspension seat and tilttelescope steering.
