Anybody have a good idea on mounting gopro to tractor?

I just bought the new gopro hero and I'm trying to think of good ways to mount it to my craftsman without putting more holes in the body or frame. I was just going to mount it to the deck lever and probably will, but I have not tested it yet. As of now I have the roll bar mount, tripod mount, curved and flat adhesive mounts, head strap, and the hat clip.

The hat clip is out of question. I don't know how the head strap will do for making a decently steady video, but I'm iffy of it falling off hitting holes. The roll bar mount seams to be my best route, but it will be a little slanted to the right. Also, my exhaust comes out right under the deck lever and its a straight pipe 2 cylinder header, its quite loud. If it helps, I top out at 20mph. I'm trying to stay away from the pole idea, like fearlessfront's gopro mount, since I drive in very tight places.

If you use a gopro, leave a reply of how you mount it to your tractors, to help give me some ideas.

They do sell suction cup mounts. if you get one of those you wont need to drill holes and it will be steady too.

I suction cupped mine to the rear fender looking forward, didn't come out too bad. Mostly you end up with a lot of shaky footage with anything you do with a lawn tractor since there isn't any suspension. I tried it with a helmet mount and it was pretty bouncy, I didn't use it because I didn't like how it was all over the place. Probably depends on how smooth the terrain is too I guess. I was in pretty rough stuff.
