That same thing happened to our 8050 powershift. Sounds like the nut on the end of the input shaft failed or bearing failed. We took the valve body off the right hand side of the tractor, then you can stick a bar into the transmission under the main shaft, if you have up and down play a split is the only way to fix it. Sorry about the bad news.

You say it will pull in reverse high range. There is no reason that it shouldn't be able to pull in low range if it will pull high range. That being said, if there's any oil dripping from the bellhousing, the big nut is probably loose. Removal of the right side fuel tank and then the power shift valve assembly will allow you to reach in from the side and get a long pry bar under the front clutch packs and see if you can move it up and down. You should get very little movement, like pretty near zero movement. If the nut has backed off it will obviously move.

Could have shared bolts off in clutch housing. What ever it is, it's a complete rebuild. MACK

I don't think it's productive for you to question why it did what it did and when it did it. You have a problem that needs to be addressed, so figure it out or don't use the tractor any further until you do. The large nut on the front end of the transmission has a history of loosening up on its own. If that isn't it, then you must have a shift control valve problem. Either way, the shift valve and fuel tank have to be removed to diagnose the problem.

Matt, anytime a power shift tractor is brought to me with a suspected major problem, I always put it in a position in the shop where it can be split. I don't want to put the valve body back on just to move it over to a different location after I have removed it. I even spin the rear wheels out for added room if it has that option before I take the valve body off. Expect the worst and hope for the best.

I am looking for someone to fix this problem for me. I am from the UK, London webcam live. But actually, location does not matter as you can get access to my computer in a remote mode through different tools. You just need to have a few spare minutes. I would be very grateful if someone can at least diagnose the issue. Let me know if you are ready to devote some time to me.

I think that you have to give more information like model, exact description of problem and your location.
