You can find used ones on Ebay for fairly reasonable prices. You can save even more by building your own with a used pump.

I think the simplest solution is to adapt a high-pressure filter (with a bypass) to connect to the front PTO. 8 GPM (or 12 GPM or more, on the larger PTs) and it wouldn't take long to circulate all your oil through it, even though the filtered oil is dumping back into the tank and mixing with the unfiltered oil. I'm not a mathematician, but it seems like 10 to 15 minutes of run time occasionally, and you'd have well filtered oil...
I don't know if these would qualify as "affordable", but this brand has filters that can handle up to 6,000 PSI spikes and has bypasses as low as 50 PSI...You need an affordable, reliable bypass setup that can handle the full flow and pressure of the PT and yet have a low enough relief setting to not destroy the filter. Maybe I am always looking in the wrong places but I have not found one. Surplus has one with the low end relief adjustable down to 125. Maybe then put a lower pressure one after that that can get down to the filter range? I am starting to get nervous already. Any idea what the pressure would be midline in the run when the PTO is in full bypass. The flows are so high i bet it is close to, if not above, the filter rating (media, not the can) even though the end of the line is open. If that is true, then you would need to run a separate return line back to the tank.
Or am I thinking about this all wrong?
