Any idea what could cause slow hydraulics? All hydraulics are slow. Tilt, Side shift, Lift and even when Lowering.

I checked the pressure on the delivery hose connector, and it is correct based on manual, at 2,500 psi. I also drained all the hydraulic oil, and filled it in with new 10 gallons. The old oil was dirty and dark red, please see second picture.

One of the possible symptoms is if it manifests itself to a significant extent when the oil is cold, there may be a disturbance in its flow (saturated filter, foreign body in the intake line - part of the valve, damaged O-ring... and the like), mechanical impurities or disturbed controls. It is also important whether the problem arose increasing intensity or at the moment... Do the pressure check at min. 60 degrees Celsius

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
