Nothing’s more frustrating than a tractor that cranks but won’t start, especially when you’ve got work waiting. If your John Deere gas engine is running rough, missing at idle, or just won’t fire reliably, worn spark plugs are often the culprit. This medium hot heat range plug with power tip delivers the steady, strong spark your engine needs to run smooth and start every time.
What You’re Getting
- 18mm thread diameter with 1/2 inch reach fits proper in your cylinder head
- Power tip design creates a hotter, more efficient spark for better combustion
- Non-resistor construction provides maximum spark energy to ignite fuel mixtures
- 7/8 inch hex makes installation straightforward with standard tools
- Medium heat range works well in most operating conditions
Built for Real Farm Work
John Deere gas engines power everything from compact utility tractors to older workhorses that handle daily chores around the farm. Whether you’re running a small tractor for mowing and light loader work or firing up that trusty gas engine for PTO work, reliable ignition makes the difference between getting started and getting stuck.
Made to Last
Farm engines work hard in dusty, demanding conditions, and your spark plugs need to keep up. This plug uses quality materials that resist fouling and electrode wear, so you get consistent performance season after season. The power tip design helps burn off deposits that can cause misfiring.
Installation Notes
Gap these plugs to your engine’s specifications before installation—most John Deere gas engines call for around 0.025 to 0.030 inches. When removing old plugs, let the engine cool first and blow out any debris around the plug wells. Thread new plugs in by hand to avoid cross-threading, then snug them down with a socket wrench.
