Thats some good information you gave me. Thanks. I'll try to look at it tomorrow. I tried once before to turn the axle by hand: jacked up the back end, took one of the wheels off, and push the bypass rod forward. The video on the 2nd page of this post shows that. But I'll do it again if I have no more odd jobs to do. I'll take some photos, maybe some closeups if I can; or maybe another video . Whatever this is I think it came from the factory like this. But not BOTH hydros. I myself can see thats highly unlikely. I've never been able to push it easily. It takes all I've got to even begin to make the wheels turn; but I'm 76 but not doing too bad for that age. I called the shop I bought it from today and asked them "what would make an MX5060 drive in forward or reverse regardless whether the bypass rods are in or out"? He had no idea, he said he'd never seen that. His guess was something internal in the transaxle, maybe a stuck valve or something to do with those valves....like you said. I said "well its that way on both sides". If the problem was just on one side, when you push both rods in then only the bad side would make the wheel move. He was puzzled. What is so odd is its both sides pull no matter where the bypass rods are positioned. So, I'll try to do what you said tomorrow. I'll let you know.
