Ed,
Perhaps you are referring to a front-end loader. My back-hoe, as most others also, has a front-end loader, which I use to do exactly as you describe...move dirt in the case where it is faster and easier to move with the loader than the dozer. I use the dozer to cut/push the dirt/clay into a pile and then the loader to carry it to the location, the dam in my case, and then use the dozer to spread and pack at the location. Its a technique that works well for me and makes use of the equipment I have. Both pieces of equipment cost about $10k.
