Description
When you're putting serious hours on your John Deere equipment, clean oil isn't just nice to have—it's what keeps those expensive internal parts from turning into scrap metal. This Baldwin BD40027 oil filter handles the big jobs, from dozers moving dirt all day to combines running marathon harvest sessions. With its large 4 11/16 inch diameter and nearly foot-long design, it's built to keep up with the heavy-duty engines that power your most demanding work.

- Robust 4 11/16 inch outer diameter handles higher oil flow rates without restriction

Built for Real Farm Work
This filter works across John Deere's heavy equipment lineup including track dozers, wheeled loaders, combines, and high-horsepower tractors. These are the machines that don't get to take breaks—whether you're pushing dirt with a dozer, loading grain trucks with a combine, or running a big tractor through marathon planting days.
Made to Last
Baldwin builds this filter to handle the temperature swings, vibration, and pressure changes that come with heavy equipment operation. The robust construction and quality filter media capture contaminants while maintaining proper oil flow, protecting your engine's expensive bearings, pistons, and other critical components from premature wear.
Installation Notes
Before threading on the new filter, wipe a thin coat of clean oil on the gasket, then hand-tighten only 3/4 turn after the gasket contacts the mounting surface. Over-tightening just makes the next change harder and can damage the seal. The large size means you'll want good access and maybe an extra hand to get it positioned right.
