Fordson Super Major hydraulic issue

[LeeAm33]

I have a 1963 Super major with a hydraulic issue. They lift no problem and hold weight etc but as soon as i clutch the tractor the hydraulics drop even when the hydraulic lever is at the top. When i release the clutch again the hydraulics go up again. Any ideas?

What happens if arms are up and you stop engine do they still drop if so you have a leak on hyd system do the arms go up and down when driving it without touching lift lever..

Lift the arms to nearly the top and pull the A S C out and see if they stay up

Hi I have check both things. Arms drop as soon as engine stopped. They do not stay up when ASC is out. Also they will only go up if the tractors PTO is engaged.

Would the last point not be normal?

With them dropping with ASC in and out means there is a leak in the cylinder most likely piston seal.
They can only go up when the PTO is engaged as it is the PTO shaft that drives the pump.

There will be a wealth of knowledge on here but you could also seek some info on the Fordson forum.
