Read articles →This is a hands-on owner walkthrough of replacing cab air filters and corroded retention hardware on a 2014 New Holland T4.95, not a generic overview. It shows both fender locations, removing stuck corroded pins with locking pliers, cleaning debris and drain channels, applying anti-seize and fluid film, and installing new filters and clips, plus rough part prices (~$14 each, ~$163 total kit). Best for current T4-series owners doing this exact job themselves.
Posted by an owner-operator (Modern Country Living) documenting real maintenance on their own tractor, not a dealer or sponsored review.
They are located in the fenders on both sides, mirror image filters, accessed by rotating small pins to pop the cover out.
Use locking pliers with hard, toothed jaws (called a vampire tool) to grab the corroded screw head and spin it out when a screwdriver cannot get purchase.
The owner says to get in there from time to time and look, since corrosion on the hardware can make the job more difficult over time.
