Hi. Im hiring a 1.5t mini-digger to level out a patch of ground and then dig the footings for my small outhouse. Does anyone have an advice on diving one of these things or anythign to look out for? The area (8m x 8m) has a gentle slop (about 8" differnce across the whole area) and I'd like to get it level before I dig the footings. Should I bother and if so, what is the best way of doing it? I notice that diggers also have a big shovel along the length of the front. Is this used for anythign in particular ? Also - what fuel do you use incase I need to top it up ? Thanks guys.
