I have a TC-25D Boomer with SuperSteer and the appropriate NH loader, it has appx 300 hours on it and has been maintain to factory specs. My first winter, I notice it would squeal really loud when you pushed full down or back on the hydro pedal, but it would quit when it warmed up. Now it squeals most of the time when the pedal is full down back or forward, reguardless of temperature. Fluids are good and filters are good. Anyone else have this problem??? ,

When you push the peddle down full you are pushing the maximum amount of oil. I would suspect you are getting a little bit of oil cavitation or the pressure release safety valve is opening. As the tractor ages the release valve spring may soften and provide less tension. I might switch to a lower cool viscosity synthetic hydro fluid and see if it goes away.
I would look back in the posts. I believe there was a similar discussion on a TC-33 or 40. ....
