Frequently Asked Questions

What filters do I need for a John Deere 850K dozer?

Broken Tractor carries fuel, air, cab fresh air, and DEF filters for the John Deere 850K crawler dozer. This includes spin-on fuel filters and fuel filter kits, primary and secondary engine air filters, a cab fresh air filter, and a DEF filter for machines with SCR aftertreatment. Match the part number to your machine to confirm the correct fitment.

What is the difference between the primary and secondary air filter on a John Deere 850K?

The primary engine air filter (SKU RE62220) is the outer filter that catches most incoming dust, while the secondary or inner air filter (SKU AT171854) is a safety element that guards the engine when the primary is removed or lets dust through. Both fit the 850K and are typically replaced as a set. We carry both for the 850K dozer.

Does the 850K use a spin-on fuel filter or a fuel filter kit?

Broken Tractor offers both for the John Deere 850K. The spin-on fuel filter (SKU RE533910) is a single element replacement, while the fuel filter kit (SKU RE525523) covers a complete fuel filter change. Choose based on what your service interval calls for, and confirm the part number matches your machine.

Does the 850K dozer have a DEF filter?

Yes, machines equipped with SCR aftertreatment use a DEF filter, and we carry SKU DZ114640 for the John Deere 850K. Fitment can depend on how your machine is configured, so match the part number or confirm with the parts team before ordering.

Will these 850K filters fit other John Deere serial number ranges?

Fitment can vary by model and serial number, so the best way to be sure is to match the part number listed for each filter to your machine. If you are unsure which filter is correct for your 850K, confirm with the Broken Tractor parts team at (800) 909-7060.
