A request for advice from the GTT braintrust:
So I wanted to change the hydraulic fluid on my tractor. It has 310 hours on it now, and according to records that came with it, the first change was done by the prior owner at 63 hours. The machine appears to have been well maintained and everything worked as it should - until now, that is. I felt pretty confident that I could handle the task with no problem since I'd done it before on my former x485 and scoped the procedure out a bit in forums here. I went to my dealership and told the parts guy I needed the supplies to change the hydraulic fluid in my 2025r. He set me up with low-vis deere fluid and a new suction screen. Thinking he knew what I needed better than I did, I walked out without a canister filter or the red dye for the fluid. My first mistake...
Everything seemed to go smoothly getting the old fluid out and the new screen in. There were very few metal shavings inside so I was happy about that.
It was probably 15 minutes that I let it drain before putting things back together and refilling. After over-filling it by about two quarts since it takes FOREVER for the sight glass to register the level of fluid (even after reading about the problems turtle had with his ) I siphoned it off to get to the correct level of new fluid.
Thinking I'm good to go, I fired it up and all seemed normal until I went to operate the loader and 3-pt. No worky, worky!!! Nothing. Zilch. Nada. Ran it at idle for 10 minutes and the sight glass sloooowwwwllly filled up while it was idling. Still no lift front or back. Did not try the steering or PTO. Honestly I was a bit worried about doing damage while running it with no fluid pressure.
After reading more about it online and re-reading the manual (where I discovered the missing canister filter) I'm at a loss for what might be the problem. Today I went and got the canister filter that I should have gotten at first, and I guess I'll keep the suction screen that I didn't need to get, and tonight I'll drain it all again and start over. While it was at the dealer I told the service manager this whole story, and he said to double check that I didn't put the suction screen in backwards so I'll do that while I'm at it tonight. Other than that, I'm clueless. I'll be much obliged for any advice you all can provide on what might be the problem, and if there is any more info you need just let me know.
