Have you replaced the hydraulic oil filter? Maybe it is restricted so that you aren't getting good fluid flow which would keep you from building the pressure that you should. Was the replacement pump a new one or a used one?

Problem is a lot worse than filter. I took the tractor to shop in John Deere shop Hernando, Mississippi. I have replaced the filter, pump , replaced all o-rings so I doubt you would be able to figure out over the internet.
I would like a refund please.
