Introduction
David Brown 950 Tractor
The David Brown 950 is a two-wheel-drive agricultural tractor produced between 1958 and 1959. As part of the 900 series, this model was designed to provide reliable mechanical power for mid-sized farming operations during the late 1950s.
Engine and Performance
The tractor is powered by a 165 cubic-inch (2.7-liter) four-cylinder diesel engine. This liquid-cooled power plant generates 42 horsepower at a rated engine speed of 2200 RPM. With a compression ratio of 17:1, the engine is built for steady torque delivery in field conditions.
Transmission and Drivetrain
The 950 utilizes a Twin-Range transmission system, providing the operator with six forward gears and two reverse gears. Power is transferred to the wheels via a 254 mm dry disc clutch. Final drive is achieved through spur gears, and the tractor is equipped with mechanical drum brakes for reliable stopping power.
Hydraulics and Hitch
The hydraulic system operates at a pressure of 2000 psi (137.9 bar) with a pump flow rate of 7.5 gallons per minute (28.4 lpm). The rear hitch is a Type II/I configuration capable of lifting 1800 lbs (816 kg). From 1959 onwards, the tractor featured the Implematic system, which provides integrated draft and depth control for improved implement performance.
Dimensions and PTO
The tractor features a wheelbase of 76.75 inches (194 cm) and an overall weight of 4230 lbs (1918 kg). It is equipped with a 540 RPM rear Power Take-Off (PTO) system, which reaches its rated speed at 1800 engine RPM, allowing for the operation of standard driven implements.
Conclusion
The David Brown 950 remains a notable example of late 1950s engineering, offering a balance of mechanical simplicity and hydraulic capability. It is well-suited for traditional field tasks and general utility work where a robust, manual-steer, two-wheel-drive platform is required.
