How much machine do you need?
Two questions. Cubes to move, and what you are building. The answer is the machine class, the hours it will take, and whether to hire it or own it.
1.5 m³A man-day. One labourer with a pick and shovel, ordinary soil.
15 m³An excavator-hour. A 2 t mini does a labourer’s week before lunch.
