Abstract
A mine roller includes a bracket having a first end and a second end. The first end is adapted to be coupled to a vehicle. A table having a center region is coupled to the second end of the bracket for rotation about the second end in a first plane. The table has first and second telescopic portions coupled to the center region such that the table is extendable relative to the center region in opposing directions of a second plane that is perpendicular to the first plane. A roller bank is coupled to each telescopic portion of the table for rotation relative to the respective telescopic portion in a third plane that is parallel to the second plane.
