JD 310D backhoe reverser problem.

[craig6]

Bought a JD 310D at a county auction. It worked fine. Was told by county it worked fine. Had it picked up and delivered. Everything worked fine. I was not around when shop man brought it into the shop to check out. When I arrived, I wanted to try it out, so I started it, cycled the parking brake switch, but it would not move. Tried alot of things, shifter, FR lever, checked wires and connections, relays, solenoids all seem to be working but still won't move. When checking the oil level, oil blew out of fill tube but level wasn't overfull. It even blew the filler cap/dipstick out, might have lost a pint or so. I believe there is a return line from the trans to the fill neck but I'm not sure what would make it push oil out like that. Anyway, it still won't move. I don't know if something happened when I wasn't around that he is not telling me about or what. Has anyone had this problem or have any answers or possibilities? Thanks for any help.
