The front end loader was always slow coming down...and has gradually gotten slower and slower coming down to the point it does not come down at all now until you shut the engine off, basically turning off the hydraulic pump and letting the oil drain back to the tractor sump.... Both of the hoses to the cylinders would have had to have been providing pressure to the cylinders because I lifted some huge loads of dirt, firewood, etc., and if they both were not providing roughly the same pressure seems like the whole frame would have bent itself to pieces..... It has always worked going up just fine....I am thinking that both lines out of the top are pressure AND drain lines depending on which way the lever is moved...but maybe there are some "O" rings worn out or junk blocking the drain holes somehow that is creating too much pressure to allow the lines to drain while the pump is actually running now days... Do you think that might be possible?

Plumb it like I told you. There's nothing on that valve but notches in the spool that mover over the holes where the hoses are hooked.

Do you want me to post a link to this on another forum so others can see it if you think I'm wrong?
