John Deere 670 with weak hydraulics

[gstrom99]

So it doesn't have a replaceable filter like an oil filter ? Dunno if it's Japanese, but sounds like it probably is. This looks like a spin-on hydraulic filter: Fits John Deere 650 670 750 770 790 850 870 950 970 990 RE27284. But looking at the service intervals (see attached file) it looks like it doesn't.

The filter to change, is #5 in your parts list. There should also be a metal screen to take out and clean. The "trans" oil is used for all hydraulic functions. The service manual will show this process.

That's super-helpful to know the tranny oil and hydraulic is all one system, thanks.

So, how do you get the metal screen out ?!? Looks like lots of crap has to be removed. Except, looks like there's a cover at the far end of the suction line connection (so on the right-hand side of the tractor) and you just remove that (and maybe one little suspension piece) ?

Guess I'll buy a new filter, replace that and the oil (I assume the oil all dumps out when I remove the screen). Can't find a part# for the screen so just clean that I guess. And go from there.

P.S. Mis-spoke earlier, the bucket DOES move slower than it did, even when un-loaded.
