Kubota B7200 4wd not working

[jdccpa]

Hello all, I have a late 80's model Kubota B7200 HST with 4wd/front wheel assist. Per the lever position, the tractor is in 4wd but the front wheels are not pulling/assisting. The lever will move a little bit (the shaft isn't seized in the case) but it will not come out of the 4wd position. I have tried moving slowly in reverse, changing directions, changing high to low range, and pulling up on it really hard....all with no success. When I pulled up strongly and was moving slowly in reverse, the front tires locked up and began sliding....letting me know that the drive shaft and linkages are all connected. To me, it appears to be an internal issue, likely related to the seized lever. Does anyone have any thoughts on this issue?

Thank you in advance for any assistance!!

If you tried to disengage the 4wd and you locked up the front wheels doing so, you have a serious internal issue.
You will need to open it up and find out what is going on with it.
