I had to read my wife this thread.... in hopes to get her to stop laughing / nagging me. I did the same exact thing on the 4wd lever on my Kubota. It has happened before where I caught my shorts and kinda tripped up getting off, but this time I got hurt. Momentum carried me (or the top half of me) off the tractor while my legs twisted and stayed on the platform. I wrenched my bad bad enough to go to the doctor. Hit the ground with my head, arms and shoulder. Nothing torn or broken, but having back surgery 3 years ago, anything this "minor" is cause for concern.
Think twice before getting off wearing loose clothing. I now hold my shorts with one hand and the FEL bar in the other.
