One does have to wonder, did the culvert or the loader come first? - a real life chicken and egg...
Yep but you can doze with a loader you can't load with a dozer. I guess you could load with a dozer if the truck was parked next to the pay pile and the dozer pushed the pay of the top of the pile onto the truck but probably would burry the truck in the process.
As far as did the culvert or the loader come first goes. I would imagine the invention of the mole loader was the result of years of hand digging out culverts until someone who had probably worked in an underground mine thought of reducing the size of a loader used down there
