I miss worded it’s the pressure control valve sorry. It’s just below the rock shaft on the right side of the tractor.- Shaggy97

4440 Lost Hydraulics
Trying to diagnose a hydraulic problem on my quad range 4440. I’ve lost steering, 3point lift, and both remotes. It all came shortly after I changed the pressure relief valve fitting that was leaking. Still have clutch and brakes. What should I start looking at first? Front pump, rear pump...- Shaggy97
