Hydrostat problems New Holland tc30

[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 hydrolics 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.

When was the last time You change Both Hydraulic filters ? There are 2 filters . Not sure , would have to get out my manual for my 2003 TC30 , but I am thinking 1 is for hydraulic controls and 1 is for HST .
I have almost 800 hours on mine and have had no issue's with the hydraulic's or HST .

I just recently bought it. Didn't know there were separate filters for each. Thanks!
