Tuscarora, MD | You will need to split the tractor and remove the 2 spd. The quad range transmission is a synchro range with a 2 spd power shift in between the clutch and transmission input shaft.
My 4430 locked up just the same way. In my case someone forgot to put the thrust washer on the clutch pack and it slowly machined the hub which broke the spring, thus locking the clutches...Very bad. New parts are very expensive. I had my local machine shop make me a new hub end. It's used almost everyday and 13 years later it is still running.
Sometimes the bolts back out of the planetary pack which is also bad. I suggest you fix it soon. It's pretty easy for someone with some mechanical experience.
Also replace the engine and pto clutch, and rear seal while you have it split. Change all filters and clean screen as they probably have grindings floating around.
Hope this helps.
