Bristoe, there has been lots of good ideas and suggestions made already, so I wont add to them. My Dad was pulling up a small oak tree, about as big around as your thumb, with a jubilee. He did several things wrong, such as pulling uphill and raised the drawbar. When the front end came up, he stabbed at the clutch, but his foot slid off the pedal. Before he could try again the tractor was coming over backward. Some how he managed to crawl between the seat and steering wheel enough that it didn't crush him. Broke several bones and spent a week in the hospital, but he's still kicking. Just be careful.
