I don't know what I did. I was waiting to send my Kubota M 8030 to the shop for a clutch. It has no clutch effect at all. The pedal still has tension all the way through, but, no release whatsoever. I could still move the tractor around by using 1st gear and low range , no problem. While on my way to park the tractor I had the brilliant idea to drag a fallen tree out of the way( I know I know!!). I started to move the tree when I bogged down. The wheels spun a few times, so I decided to change positions. After unhooking from the tree, I went to move the tractor and, it wouldn't move at all. I can put it in high or low range and any gear but it does nothing. It still runs as usual, all hdy's still work, and the pto still turns. I didn't hear any noise or any other indication that I broke something. I'm hoping the clutch just finally gave out completely, and I didnt break anything internal. What can I check for clues to what the problem is? Thanks for your help.
