An excavator is usually on tracks and has a long arm to reach out and dig holes and trenches, such as the one above. A micro excavator is a smaller excavator usually used in tight spaces such as under houses, rooftops and backyards. These types of excavators are smaller and lighter than original excavators are and are built for confined spaces. Micro excavators range from 600mm-1000mm wide, and are used to dig holes for swimming pools, remove large rocks or stumps and dig trenches for sewer, storm water pipes, electrical, or communications conduits.
