Introduction
Big Bud 525/20 Four-Wheel Drive Tractor
The Big Bud 525/20 is a heavy-duty four-wheel drive tractor manufactured in Havre, Montana, USA, between 1979 and 1982. Designed for large-scale agricultural operations, this machine represents a period of high-capacity tractor engineering focused on extreme traction and power.
Engine and Performance
The tractor is powered by a Cummins 12V149 liquid-cooled, 6-cylinder turbocharged diesel engine. With a displacement of 1150 cubic inches (18.8 L) and a bore/stroke of 6.25x6.25 inches, the engine delivers a rated power of 525 hp (391.5 kW) at 2100 RPM. The intake system utilizes a dual dry element air cleaner to ensure engine longevity under dusty field conditions.
Transmission and Drivetrain
The drivetrain features a Fuller transmission system providing 12 forward gears and 2 reverse gears, allowing for precise speed selection during heavy tillage or hauling tasks. Power is delivered through a four-wheel drive configuration, ensuring maximum tractive effort. The steering is managed via a hydrostatic power steering system, which facilitates maneuvering the machine's 150-inch (381 cm) wheelbase.
Operator Environment and Electrical
The operator station comes standard with the Cruiser Cab, designed to provide comfort during extended operational hours. The electrical system is built on a 24-volt starter circuit with a negative ground configuration, utilizing an electric starter for reliable ignition.
Conclusion
The Big Bud 525/20 is engineered for high-intensity agricultural applications requiring significant drawbar pull. Its robust powertrain and standard four-wheel drive configuration make it suitable for large-acreage farming and heavy-duty implement management.
