Steering and loader work slow and jerky

JD5425 3000 hrs really great tractor but last two months have had trouble with the hydraulics. Improves some with higher engine speed. Feels the same in cold or warm conditions. Level is up nice, but have never changed the fluid or filter. Any suggestions?

So you have never changed your hydraulic filter/fluid in 3000 hours and wonder why you are having hydraulic issues?
I’d change the fluid and filter right away and hope that’s the only thing you have to do.
Good luck!

Check for a screen filter also. You just need to clean it out and put back in.

Hopefully the filter is just so plugged that its causing cavitation. Considering the hydro system service interval is 600 hours, theres a pretty good chance that its trashed.

If his hydraulic filter is a magnetic base “donut”, it may be plugged with metal flakes.

Ok thanks guys, your comments make sense. I see in the manual that there seems to be two or three separate reseviours for the hydraulic oil. Is that correct? one is for the sysciShuttle -10 gals. and one for the power Reverse 12 gal. So that's a lot of oil. Do you normally use the JD HyGuard, or something else like from Tractor Supply? HyGuard seems to be nearly twice as much as others. Is it better stuff?
So I do I find the drain plugs?
Thanks for your help with this.

Between new oil and cleaning/replacing filters, the filters are the more important element. If the oil can't get through the clogged up filters, it can't get to the pump. When increasing the revs doesn't help any more, the hydraulic pump will be scrap.

On which oil to use, look at it this way: The original oil was probably HyGuard. It's not only twice as expensive, it's probably better. The original oil lasted 3000 hrs. How can you argue with that?

I wonder if it lasted 3000 hours or if it's totally shot and destroying the system? I'd never, never consider running any lube oil that far, motor or gearbox.

If it was mine, I think I'd spruce it up and trade it in.....Why change the oil when you can change the tractor instead....lol

I don't think we are talking about running the same oil 3000 hrs, more about whether to replace it with Tractor Supply generic or HyGard. He's in NY. I'd use Hy-Gard in their winter viscosity.
