  1. Jeff here is a link to some John Deere branded items for this engine: https://www.greenpartstore.com/John-Deere-Model-GX95-Rear-Engine-Rider-Parts.html

    Oil Filter: John Deere Engine Oil Filter – AM107423
    Air filter: John Deere Paper Air Filter – AM101191 (will also need the foam pre-filter)

    As always, you can may find better pricing online or at your local dealer. My JD dealer usually stocks these items as my JD mower has this engine. I’ve also found compatible items on Amazon at decent prices.
