Frequently Asked Questions

What filters do I need to service a John Deere 850B dozer?

Broken Tractor carries full filter coverage for the John Deere 850B crawler dozer, including primary and secondary air filters, fuel filter cartridge, fuel/water separator spin-on, engine oil filter spin-on, hydraulic filter, and cab air filter. This lets you handle both routine service and full maintenance intervals from one source. Match the part numbers listed for each filter to confirm the correct fit for your machine.

Which primary air filter fits a John Deere 850B dozer?

We carry two primary air filters listed for the 850B, SKU AT50526 and SKU AR61967. Both cover the 850B along with other John Deere construction and forestry models. If you are unsure which one matches your machine, confirm the part number against your existing filter or check with our parts team.

What is the difference between the primary and secondary air filter on the 850B?

The primary air filter is the outer element that catches most dust and debris before it reaches the engine, while the secondary air filter is the inner safety element that provides additional protection. For the 850B, Broken Tractor offers primary air filters (SKU AT50526 and SKU AR61967) and a secondary air filter (SKU AR79680). Replacing both helps keep dirt out of the engine during service.

Does the 850B dozer have a cab air filter?

Yes, enclosed 850B machines use a cab air filter to improve in-cab air quality. Broken Tractor carries a cab air filter, SKU RE12793, listed for the 850B and other John Deere dozer models. Confirm the part number matches your cab setup before ordering.

What hydraulic filter fits a John Deere 850B dozer?

We carry hydraulic filter SKU AR94510, which is listed to fit the John Deere 850B among other John Deere models. This element supports steady hydraulic flow and pressure during operation. Match the part number to your machine, and if you need help confirming fitment, call our parts team at (800) 909-7060.
