Tc-30 hydrostat problems

[Joesmith101]

Not sure if this is the proper location to post my problems. I'm new to this site.
But on my 2002 new holland tc30. When I push the hydrostatic foot pedals it makes a loud growling like its at low idle trying to take off in high. But the tractor is on the low side at high rpm. And the hydrostat fails under a load and will completely stop working when pushed under a load. The problem is in forward and reverse.
All tractor controls on hydraulics continue to work fine. And tractor runs fine. The problem seems to be intermittent but is occurring everytime I use it.
I'm not sure what to look for or how to trouble shoot further to fix the problem?
Thanks.

Joe,
I have a similar problem on my TC45D. On mine, pushing the forward or reverse pedal when the engine is off is fairly easy. However when the tractor is running pushing the forward pedal is very difficult. Reverse works the same as when the engine was off. My problem just started a short time ago but has happens every time I've used it recently.
If you tried anything or find a solution, please post. Thanks.
