Introduction

Big Bud 650/50: Heavy-Duty Articulated Tractor

The Big Bud 650/50 is a high-horsepower articulated four-wheel drive tractor produced between 1980 and 1981 in Havre, Montana, USA. Designed for large-scale agricultural operations, this machine is engineered for heavy traction tasks and high-output fieldwork.

Engine and Powertrain

The tractor is powered by a Detroit Diesel 12V92T, a liquid-cooled V-12 turbocharged diesel engine. It features a displacement of 1104 cubic inches (18.1 liters) and produces 650 horsepower at a rated speed of 2100 RPM. The engine generates a maximum torque of 1915 lb-ft at 1300 RPM, providing the necessary force for demanding pulling applications. Power is managed through a Twin Disc TD-92-2610 power shift transmission, offering 9 forward and 2 reverse gears.

Mechanical Configuration

The 650/50 utilizes an articulated power steering system, allowing for maneuverability despite its significant size. Braking is handled by a pneumatic disc brake system. The tractor is equipped with 35.5-32 tires on both the front and rear axles to maximize traction and distribute its substantial base weight of 60,000 lbs (27,216 kg).

Hydraulics and Dimensions

The hydraulic system is of the closed-center type, featuring a pump flow of 36 gpm (136.3 lpm) and a total reservoir capacity of 100 gallons (378.5 liters). With four valves available for implements, the system is designed for high-capacity hydraulic requirements. The machine measures 264 inches (670 cm) in length, 130 inches (330 cm) in width over the fenders, and has a wheelbase of 157 inches (398 cm), providing a stable platform for field operations.

Operator Environment

The unit is fitted with the 'Cruiser Cab' as standard equipment. This enclosure includes air conditioning to maintain operator comfort during extended hours of operation in extreme environments.

Conclusion

The Big Bud 650/50 is a specialized tractor engineered for large-scale, heavy-duty agricultural environments where high drawbar pull and significant hydraulic capacity are required.
