to-30 hydraulics

[farminfool]

Was abusing my to-30 pulling a tree out with rear blade on back for extra traction.
After many tries it came out but now I have no lift on three point arms.Arms lowered with control but no lifting. Checked for pressure at port under seat and nothing.. Where do I start looking now

I had the same problem on mine. I replaced the pressure relief valve on the hyd pump.

Had similar thing happen (years back) on my TO-30 and followed the I&T Manual for R&R of hydraulic pump. Said to FIRST remove the side ports and reach in and jiggle something to see if it was stuck.

(I failed to read that FIRST suggestion, until after draining and removing the pump and having it on my workbench ready to work on it. )
