No worries, the rider is going to use a karate block on the tumbling snowmobile.

Just came across what looks like a near death snowmobile experience in the mountains. Have you ever dreamed of being attacked with a chainsaw? This is like that only instead of a chainsaw it is a tumbling pissed off snowmobile chasing the offending rider down a steep narrow rocky couloir.
The rider shifts into a high speed spinning and tumbling slide down the steep chute. He attempts to grab and hold the tumbling speeding 600 pound snowmobile.
You can see the video from the perspective of the guys at the top of the mountain:
