The sheepsfoot roller is another piece of equipment that is not common in Newfoundland as it is best used on soil types that are not present here. It gets its name from the imprint left on the soil after it has passed over; it looks like a herd of sheep had just walked over it. Working on a site where the soil is being compacted by a sheepsfoot roller makes it difficult to walk around, the indents left behind are about 6" in diameter and about 4" deep. It is like walking around on a large 'Bat the Mole' game.
POINTS TO REMEMBER:
- drum with metal knobs called feet
- feet reduce contact area and therefore increase pressure
- good for compacting silts and clays
