I know exactly, what You mean saying "...M8540 runs out of traction...". But that depends on design and works to do. I need dozer for road repairs, some landscaping, rocks pushing ... well, snow is the last thing I need it for.
Talking about dozer I mean similar like in the following video:

Interesting piece of equipment; I've never seen one like that. It seems as though it would work well for the tasks you described.
