When you're running a Valtra, Valmet, or Massey Ferguson tractor day after day, you know how important clean oil is to keep that SISU 4-cylinder engine humming. This oil filter captures all the metal shavings, dirt, and combustion byproducts that want to turn your engine oil into an expensive grinding compound. It's the kind of part you don't think about until it's too late—but replacing it regularly keeps your tractor running strong season after season. What You're Getting Full-flow design ensures every drop of oil gets filtered for maximum engine protection High-capacity filter media traps contaminants while maintaining proper oil pressure Anti-drain back valve keeps oil in the filter so you get instant lubrication at startup Spin-on design makes oil changes quick and mess-free Built to handle the temperature swings and vibration of real farm work Built for Real Farm Work This filter fits a wide range of European tractors including Valtra A-Series, N-Series, and 600-900 Series models, along with Massey Ferguson 3600 and 4400 Series and select Case IHC CS models. These are the utility and mid-range tractors that handle everything from loader work and hay operations to field cultivation and general farm chores—the kind of versatile machines that need reliable filtration to keep earning their keep. Made to Last SISU engines are known for their durability, but they depend on clean oil to reach their full potential. This filter uses quality materials that stand up to pressure fluctuations and temperature extremes, with a robust housing that won't crack or leak even when things get rough in the field. Good to Know Change this filter every time you change oil—typically every 200-250 hours depending on conditions. Hand-tighten it snug after the gasket contacts the mounting surface, then turn it another 3/4 turn. No need for a filter wrench unless you're removing an old one. A little oil on the gasket before installation makes the job easier and helps prevent leaks.
