Oh yes, ice sucks! Even for tracked vehicles I'll bet.
You do not want to be on ice with a steel tracked tractor. You now have a
bunch of ice skates. My uncle slid sideways down an ice covered hill on a
crawler. In Spokane a friend had the bright idea of driving his crawler up
an ice crusted hill in the hope that it would break up the ice. It slid
into the ditch and was left there until spring melted the ice.
