Tractor farmall H

Got this tractor in on a trade. Not sure if it runs. All cylinders have a mix of diesel and marvel mystery oil in them. I believe its been 12v swapped. It does turn free. Was told loader was put on in 2007 and operated like it should and was parked due to the fella buying a loader. 1000obo. You haul and load as I do not have a way to get it on a trailer but am willing to help.
