Introduction
John Deere 950 Compact Utility Tractor
The John Deere 950 is a compact utility tractor manufactured by Yanmar in Japan, produced between 1978 and 1989. Designed for versatility in agricultural and landscaping applications, it served as a robust entry in the compact segment of the era.
Engine and Performance
The tractor is powered by a Yanmar 3T90-J engine, a 3-cylinder liquid-cooled diesel unit with a displacement of 1.7 liters (105 cubic inches). It features a bore and stroke of 90 mm and operates at a rated speed of 2400 RPM. The engine produces a gross power output of 31 horsepower (23.1 kW) with a compression ratio of 20.4:1.
Transmission and Drivetrain
The drivetrain consists of a gear-type transmission providing 8 forward and 2 reverse speeds, utilizing a 210mm dry disc clutch. Tractors manufactured after 1984 (serial number 20001) are equipped with a live two-stage clutch to improve operational control. The machine is available in either two-wheel or four-wheel drive configurations.
Hydraulics and Hitch
The hydraulic system is an open-center design operating at a pressure of 2030 psi (140.0 bar). Hydraulic fluid capacity varies by production year, ranging from 4.75 gallons (18.0 L) in early models to 5.25 gallons (19.9 L) in later units. The rear hitch is a Category I three-point hitch featuring position control for implement management.
Dimensions and Operator Station
The John Deere 950 features a wheelbase of 68.9 inches and a ground clearance of 15.3 inches. The operator station is protected by a two-post Roll-Over Protective Structure (ROPS). Steering is manual by default, with power steering available as an optional feature. Braking is handled by mechanical expanding shoe differential brakes.
Conclusion
