I have a diesel International 2504 with a T/A. The other day I was using a post hole digger then moved it to another job site. It worked flawlessly... I started it up a few days later and now I have no power steering, any hydraulics (3pt or otherwise), and the PTO won't engage. The tractor drives fine, but it takes 3 grown men and a small elephant to turn the wheel without power steering. Any ideas of where to start? I was thinking the hydraulic pump, but the PTO doesn't run on hydraulics - or does it? This is a newer machine to me and I've done work on most of the rest of the machine, but this one has me stumped where to start. I really don't want to start splitting the machine blindly. Thanks for any and all help!
