ABSTRACT:
A grinding machine to remove markings such as painted lines from a paved surface includes a wheeled carriage to be moved over the paved surface. A grinder is positioned beneath the carriage to contact and grind the paved surface. A suspension acts between the carriage and the grinder to allow the grinder to follow the profile of the paved surface as the grinding machine is moved thereover. A drive is supported by the carriage to actuate the grinder.
