loader arm goes very slow on New Holland L778 skid steer?

Question

when i move the loader arm it goes very very slow and when i move the bucket it is at normal speed, 2 filters i have replaced and it still does it, i have checked the linkage lock and it is fine. i took the back gaurd of the whole skid-steer to see if i can find anything, but i need more information if io am going to tear into it more.

Answer 1

The valve could have defective seals, or the piston seals in the cylinder are worn. Try hooking up another cylinder to the lines, it will tell you if the problem is in the cylinder or the valve.
