I had a tracked skid, they are NO dozer, UNLESS you buy the latest greatest Case skid model that can be set up as more dozer than skid, but it's designed to be both.
I've heard this before, a skid will push or pull like a dozer, a skid dealer here insisted it was true, so I challenged him to bring it over and we would put his big, tracked skid up against my little dozer in moving dirt, winner owns both free and clear. He started back pedaling right then...
Some people don't need a dozer, for them maybe a skid would be a better choice, but it won't be no dozer and that's for sure.
