When your John Deere’s engine starts running rough, missing under load, or getting hard to start, it might be time to check those spark plugs. A worn plug can rob you of power and fuel economy just when you need your tractor running at its best. This medium heat range plug keeps your engine firing cleanly and consistently, whether you’re pulling through tough ground or running PTO work all day.
What You’re Getting
- Medium hot design handles a wide range of operating conditions without fouling or overheating
- 14mm thread with 3/4″ reach fits properly in your engine’s combustion chamber
- 13/16″ hex makes installation and removal straightforward with standard tools

Built for Real Farm Work
This spark plug is designed for John Deere tractors that see varied operating conditions – from cold morning starts to hours of steady field work. Whether you’re cultivating, mowing, or running hydraulic implements, this plug maintains consistent ignition across different engine loads and temperatures.
Made to Last
Farm engines work hard, and spark plugs take a beating from temperature swings, vibration, and varying fuel quality. This plug is built to handle the demands of agricultural work, maintaining proper gap and electrode condition through extended service intervals.
Installation Notes
Thread the plug in by hand first to avoid cross-threading, then snug it down to the proper torque spec. Don’t over-tighten – the 3/4″ reach is designed to position the electrode correctly in the combustion chamber. Check your gap before installation and replace plugs as a set for best performance.
