The John Deere 950 is a utility tractor that was made from 1978 to 1989. It's a small, sturdy machine with a 2WD chassis and manual steering. The tractor is powered by a Yanmar 3T90-J diesel engine with 3 cylinders. This engine is liquid-cooled and naturally aspirated, producing 31 hp at 2400 rpm. The engine's power and size are below average compared to other tractors. This tractor has a gear-type transmission with 8 forward gears and 2 reverse gears. It features a three-point hitch at the rear, which is useful for attaching various implements. The 950 also has a PTO (Power Take-Off) that can run at 540 rpm, allowing it to power different attachments. With an open operator station and a two-post ROPS (Roll-Over Protective Structure), it provides basic safety for the driver. The tractor's compact size, measuring 122 inches long, 53.3 inches wide, and 53.1 inches high, makes it easy to maneuver in tight spaces. Its operating weight of 2700 lb is relatively light compared to other tractors.
