Last Updated: September 2024

Overview

The John Deere 850 is a compact utility tractor that was made from 1978 to 1989. It's a small but capable machine, perfect for light farm work and yard tasks. This tractor has a 2WD chassis and manual steering, making it easy to handle in tight spaces.

Under the hood, the John Deere 850 has a Yanmar 3T80-J engine. This diesel engine has 3 cylinders and puts out 25 horsepower, which is below average for tractors but good for its size. It has a liquid cooling system to keep it running smoothly. The tractor has an 8-speed forward and 2-speed reverse gear transmission, giving the driver good control over speed. It also has a rear three-point hitch and a 540 rpm PTO, useful for attaching and powering various tools. At 2,400 pounds, it's a lightweight tractor that won't compact soil too much. The open operator station with a roll-over protection system (ROPS) keeps the driver safe while working.
