When you’re baling hay on a dusty day or cultivating bone-dry fields, your air filter takes a beating. A good pre-cleaner stops dust and chaff before it ever reaches your main filter, doubling or tripling filter life and keeping your engine breathing easier. This 4-inch top spin assembly does exactly that—using centrifugal action to spin out the heavy particles while letting clean air continue to your filter.
What You’re Getting
- 4-inch inlet diameter fits larger air intake systems on mid to full-size tractors
- Top spin cyclonic design throws dust outward while clean air flows through the center
- Compact 9.39-inch height clears most hood configurations without modifications
- Durable construction that handles the vibration and temperature swings of farm work
- No moving parts to maintain—just mount it and let physics do the work
Built for Real Farm Work
This pre-cleaner is sized for tractors with 4-inch air intake systems, typically found on utility and row-crop machines in the 75-150 horsepower range. Whether you’re running through dusty harvesting operations, working dry cultivated ground, or dealing with the clouds of chaff that come with hay and straw work, this assembly keeps the worst debris from reaching your expensive air filter.
Made to Last
The robust housing handles the constant vibration and temperature changes that come with tractor work. The cyclonic separation chamber spins particles outward where they’re ejected through slots, while filtered air continues down to your main air cleaner. It’s simple, reliable technology that’s been protecting engines for decades.
Installation Notes
This assembly mounts between your air intake and main air cleaner housing. The 4-inch inlet should match your existing air intake pipe diameter. Make sure the discharge slots face downward so separated dust can fall away freely, and check that the overall height clears your hood and engine components before installing.
