tl90a hydraulics work fine when cold. when tractor warms up hydraulics wont work at idle. rpm's must be 1250 or better to work. any ideas?

can you be more specific about what wont work?
or what it does actually do.. whine, squeel, nothing at all?
Could be a worn out pump. Do you have a pressure gauge?
Can you put a hard number on 'warmed up'? ie. 140*, 180*, 220*? Actual readings on the filter and the top and bottom of the hydro case please, don't guess.

When was the hydro filter changed last?

What is the time frame between start up and hydraulics not working?
