Introduction
Big Bud 16V-747: Heavy-Duty Articulated Tractor
The Big Bud 16V-747 is a specialized four-wheel drive tractor produced in 1978 in Havre, Montana. Recognized as the largest tractor manufactured in the 20th century, this unique machine was custom-built for Rossi Farms to perform deep tillage operations.
Engine and Powertrain
The tractor is powered by a 16-cylinder, liquid-cooled, turbocharged and intercooled diesel engine with a displacement of 1472 cubic inches (24.1 L). It generates a gross power output of 960 hp (715.9 kW) and 2500 lb-ft (3390.0 Nm) of torque at 1200 RPM. The power is managed through a Twin Disc power shift transmission, providing 6 forward gears and 1 reverse gear.
Hydraulics and Mechanical Systems
The hydraulic system utilizes a load-sensing pump with a total flow capacity of 65 gpm (246.0 lpm) operating at 2000 psi. Mechanical control is facilitated by articulated power steering and pneumatic braking systems, ensuring handling for a machine of this scale.
Dimensions and Construction
The tractor features a wheelbase of 195 inches (495 cm) and an overall width of 250 inches (635 cm). Its shipping weight is 95,000 lbs (43,092 kg), which can be ballasted up to 130,000 lbs (58,968 kg) to optimize traction. It is equipped with 35x38 tires on both the front and rear axles.
Conclusion
The Big Bud 16V-747 represents a singular milestone in agricultural engineering, designed exclusively for extreme soil engagement tasks such as deep ripping. Currently preserved as a museum piece, it remains a reference for heavy-duty tractor design.
