This week I have been running a Lull for a mason on a commercial cold storage project and was watching the excavator spread base course with a D5 dozer, they had 4-5 quads hauling but thought I could have easily kept up with the 70XT. Has anyone ever read or witnessed a skid vs dozer comparison? Something that would compare purchase price, maintenance and production between the two? It was something I was wondering as I was shivering away the day.
