Introduction
Big Bud KT525: High-Capacity Four-Wheel Drive Tractor
The Big Bud KT525 is a high-horsepower four-wheel drive tractor produced between 1977 and 1978. Manufactured in Havre, Montana, USA, this heavy-duty machine was engineered to meet the requirements of large-scale agricultural operations during the late 1970s.
Engine and Performance
The tractor is powered by a 6-cylinder Cummins turbocharged and intercooled diesel engine. With a displacement of 1,150 cubic inches (18.8 liters), the engine produces 525 horsepower (391.5 kW) at a rated speed of 2,100 RPM. This liquid-cooled power unit is designed for sustained high-torque output necessary for heavy tillage and traction tasks.
Transmission and Drivetrain
Power is transferred to the ground via a Fuller Road Ranger transmission system. The drivetrain provides 13 forward gears and 2 reverse gears, allowing the operator to select the appropriate speed for various field conditions. The configuration utilizes a 4x4 all-wheel drive system to maximize traction.
Hydraulics and Steering
The KT525 features an open-center hydraulic system. It delivers a total hydraulic flow of 44 gallons per minute (166.5 liters per minute), with the steering circuit and the main pump flow each contributing 22 gallons per minute (83.3 liters per minute). The vehicle is equipped with hydrostatic power steering to manage its substantial mass.
Dimensions and Chassis
The tractor has a shipping weight of 43,000 lbs (19,504 kg), providing significant ballast for heavy draft work. It rides on 30.5x32 agricultural tires on both the front and rear axles. A standard factory-installed cab was provided to ensure operator environment control.
Conclusion
The Big Bud KT525 is a specialized high-capacity tractor designed for heavy-duty agricultural environments. Its combination of a high-displacement Cummins engine, robust manual transmission, and substantial operating weight positions it as a machine suited for large-scale soil cultivation and intensive field operations.
