MF gc 2310 2375 backhoe doesn't work.

[vwdoc]

None of the controls work on the back hoe. It did it once last year and has been fine. I swapped the spool valves and made shure the fluid is flowing good, I swapped the input lines and blew the fluid out both ways... seems to be getting great flow. change hydraulic fluid & filter every 2 years using MF dealer parts. Tractor goes back & forth fine and front bucket works great.. I figured it would be one of the valves in the block... Any help would be great thanks..
And machine is a 2004 and has 315 hours on it.

You might want to post in the Massey Ferguson Owner/Operating Forum with a more detailed description. It is confusing to read.

Ok I will post it there. I figured hydraulics and the hydraulic block on these compacts were very close to being the same. but I don't understand what's confusing Please explain..
