B2620 HST that has never given me any hint of trouble. Currently at 409hrs. At 400hrs I did the full required svc. This included full change of hydraulic oil and filters. I used SUDT2 and a Baldwin and a Donaldson filter. For the 8+ hours since the change, I have had zero issues.
Yesterday I went out to mow in 94deg weather with my finish mower. Before starting tractor, I checked all fluids due to recent maintenance and all were WNL. At end of almost 2hr mowing in high heat, neither the 3pt arms of the loader arms would move at high rpms. PTO and HST drive worked fine. If I brought engine RPMs to idle, the 2pt and loader arms would move but very slowly. Hydraulic hoses and fittings were VERY hot!
I brought tractor back to shed and shut it down. I did not have time to troubleshoot too much before I had to leave. Doing the online troubleshooting now. Postmortem as I left the farm... no visible leaks anywhere on or below tractor. After sitting for a few hours, hydraulic fluid dipstick indicted normal level and appearance of the newly changed SUDT2.
My online research reveals primary culprits as - clogged filters, faulty relief valve, air in lines, or failing pump. There seems to be a good bit of dogma for using OEM filters but I also see people saying they have had great results with Baldwin and Donaldson filters. I guess my first effort will be to drain SUDT2 into clean buckets and put in OEM hydraulic filters. Then make sure I bleed all the lines. I am also curious to see how it behaves when I am out there this coming weekend and start it up cold and run the loader and 3pt arms without doing anything else.
Any thoughts on other directions in which to head? The fact that this is all happening within 10hrs of a major fluid/filter change makes me feel that this is all self inflicted.
