The John Deere 855 is a classic compact tractor from the 55 Series. It’s powered by a 24‑hp Yanmar engine and has good lifting capacity.

Understanding these specs helps you know how your machine performs and makes sure you buy the right parts that fit correctly.
Overview of the John Deere 855
The John Deere 855 is manufactured by John Deere at two plants in the United States: Horicon and Augusta. Its size and power are between small garden tractors and large agricultural tractors, so it is very suitable for industrial owners, small farmers and people who do garden maintenance.
In the final years before the shutdown, the tractor cost about $16,000 new. It wasn’t cheap at the time. But it is durable and versatile, which is why it is popular. Also, John Deere has a derivative model —John Deere 856. This version is primarily used for grass maintenance work such as lawn mowing.

Common JD 855 Problems
Some common issues with the John Deere 855 include:
- 4×4 System Failure: A lot of owners have issues with the 4-wheel drive not working. This is usually caused by a worn front driveshaft, or worse, damaged gears inside the front axle. You can check it by seeing if the driveshaft turns when you put it in 4WD.
- Engine Won’t Shut Off: Some people find the engine keeps running even after turning the key off. This is almost always the fuel shut-off solenoid on the injection pump. It just needs to be adjusted or replaced.
