ABSTRACT:
A machine for levelling a surface has ground engaging levelling members pivotally mounted on a main frame for back and forth vibratory or oscillatory motion relative to the main frame in a normal direction of travel of the machine. Each levelling member has a longitudinal axis which extends laterally with respect to the normal direction of travel of the machine and there is an eccentric drive for providing the back and forth motion which may be connected to a power takeoff shaft of a tractor.
