Thanks for your reply gfp55, yes it is a hydro transaxle! The transaxle doesnt seem to be locking the wheels as the mower will move forward and back ok but i cannot get it out of field because it is on a hill and i cant physically push it uphill even with help and i cant get a car or big tractor anywhere near it to tow it up. I removed the cutting deck but is still too difficult to move.
The only thing i thought it could be by looking at it was the transaxle. I turned the rear wheels when mower was jacked up off the ground and the wheels turned in opposite directions....just letting you know in case that helps at all.
