Single pump, open center hydraulics. Not as high performance as a
closed
center system, but much cheaper and simpler. You can probably
replace
the pump entirely for a few hundred $. Of course before you replace
the
pump be sure to check the relief valve since if that has an issue
it's
like $25. I got a small tractor with loader that had poor hydraulic
performance and all I had to do was clean and readjust the relief
valve
to fix it.

Maybe I'm a pessimist, but I'd be prepared to drop $3K or don't
start.
of course this is to get it back like new - rebuilt pump, new
fluids,
new filters, new guage, relief valve, and a few other gotchas that
always come along (like hoses that will pop right away, cylinder
seals
etc). I've repaired a LOT of tractors and the costs are always high.

Can you divide them into more and less unreasonable?

Does having machine tools generally help? I made or modified steel
parts for the pump, its drive, the relief valve, return manifold +
strainer and cylinders for my homebrew but I had to buy the new piston
seals and hoses and pressure-side fittings.
