John Deere 5520 jumpy hydraulics steering suction screen clogged

This is a narrow, hands-on repair clip, not a review: an owner troubleshooting jumpy hydraulics and steering on a John Deere 5520 traces the problem to a clogged intake suction screen located behind the PTO, pulls it out, and shows just how dirty it is before cleaning it with starter fluid and a brass brush. Useful for 5520 owners chasing the exact same symptom; skip it for specs or walkarounds.
