The hitch pump has nothing to do with the power steering . That works off the MCV pump . So here is what to do First off make sure that you are indeed full on the hyd. oil or above the mark . Change the filter install a new filter and gskt. First try and run the tractor at around 1800-2000 RPM and turn the steering wheel to the left and keep turning it , if it does not pick up prime in a couple min. then you can look on the back side of the MCV valve housing and on the back side of it you will see a plug that takes a 5/8ths wrench it will be the small one towards the bottom Make sure that the tractor engine is shut down , Remove that plug Get back up on the tractor and start it up BUT BGE READY TO SHUT IT DOWN FAST as that little plug can pump out a lot of oil real fast when it does pick up prime . There could be several things that have caused this problem . (1) your MCV pump is getting weak (2) the O/Ring between the speed transmission is old and hard and lost it's sealing (3) you could have a stuck valve in the MCV (4) the sump check plug is leaking . (5) you could have a crack in the suction tube and be sucking air .Now if when you pull the dip stick and it say's that you are down JUST A GALLON IT LYES you may be down 5 gallon. If you run a loader on that tractor when the loader is up your level in the transmission is way down so it maybe in your best interest to over fill by five gallon.

Today's Featured Article - Fabrication (Who Me? Make it myself?) - by Chris Pratt. First of all, what are the reasons for not fabricatin your own parts? Most judgements on what should be purchased rather than fabricated stem from: Originality - If the tractor restoration is to be 100% original, it is likely that you should spend the time and money to locate the component in the used or New-old-stock market. Since this can be extremely difficult, you may want to fabricate the item or purchase a modern replacement temporarily, but eventually, you s ... [Read Article]
