Some cool stuff. I know when I worked on towers, many of them were remote and required chains, a company ski-doo or 'Argo' to get there in the winter. This would be way more practical!
I wonder what the price tag would be on those. I wouldn't be surprised if it topped 10K. I wonder if just having them on the front wheeels would be enough, since the rears would be running in the tracks of the fronts anyway.
