Read articles →This is a hands-on repair video, not a walkaround: it targets a specific frozen-up rockshaft control valve on the 4000 series (three-point hitch arms stuck or unresponsive), a common problem when a backhoe replaces regular use of the hitch. It walks through removing the six-bolt cover, freeing seized solenoids with WD-40 and gentle heat, replacing three O-rings, resetting the lowering adjustment nut, and resealing the cover, framed as a way to avoid a roughly $1,000 dealer valve replacement. Best for owners troubleshooting stuck lift arms themselves.
