I will give you the best history that I can.
I have had this tractor for 40 years and for the most part it worked fine. For the last few years when I would move the lever for forward or reverse, there would be a slow start of movement on initial cold start up.
This last weekend the marginal engine drain plug failed and I needed to put in a larger drain plug. That fixed the oil dripping from the engine.
To move the tractor I pulled up on the lever that depresses the two valves on the top of the transmission like I have done hundreds of times to put the tractor into neutral.
Finished with the engine drain plug and tried to move the tractor and it would not move. Nothing, but then it jerked forward when pushing the lever forward. Some times it seemed that the forward and reverse was being engaged at the same time.
Same thing happened in reverse. I played with it a few times and then it started to work kind of normal.
I started cutting the grass and got about 1/2 way finished when it just stopped. I took off the cover to inspect the two valves and found the right valve pin depressed into the nut. I took the valve off and tried to clean it but it did not seem to help. I positioned it in he up position and reinstalled it. Still no movement.
I dragged it into the garage and now it seems to be in neutral.
As noted earlier the input to the transmission seems to working properly. The linkages on the left side of the transmission move.
I now have nothing.
Thanks for your help.
