JD 1030 Hydraulics slow when hot.

Hello I have an old John Deere 1030. I am using TDH fluid in it but when the track runs for 30 minutes or longer I can feel the hydraulics getting weak.

Is this a fluid issue or do the pumps get weak over time and I need to replace it? Or rebuild it?

Thanks
 

Does THD hyd oil meet spec's of J20C? How many hrs of use since hyd filter was changed & hyd oil suction screen checked/cleaned? Only correct method to determine hyd problems is by performing good diagnostic procedures. One thing to do is be sure hyd filter relief valve(items 18-20) isn't stuck open.
