I have a similar problem, JD E130. I zoned out and ran over the tree root. Mower died. Disengaged pto (manual) and restarted tractor, running fine, but tractor won't move because the blade is stuck in the root. Can I just try to take the blade off and roll the mower off to a safe place where I can replace the blade? I don't have a mower jack, winch or a truck. Thanks for your help!
