John Deere 670 with weak hydraulics

[RustyShackleford]

The JD 870/970/1070 models also have a spin-on throwaway cannister style transmission/hydraulic filter in series on the suction side.

Ours has that too. And of course I'll change it too.

Like "qualsite" says, the screen is commonly found to be covered with crud and/or smashed. Straighten it out and reuse. The screen usually fits loosely over a couple of projections. It is not a fluid-tight fit at all. You can make your own with 200 mesh stainless steel hardware cloth from Ace hardware, or even sew on patches with stainless steel thread.

Seems odd that it's that fine of a mesh and yet not fluid-tight.

I realized I better have a filter-replacement plan in place before I drain the system. I don't see this stuff at Ace. But @rScotty does this look like the right stuff ?
