A self-cleaning mounting system for a ground roller assembly to be used on a mower such as a flail mower including a stationary sleeve bearing positioned on mounting shafts extending from either end of the ground roller. The stationary sleeve bearing is positioned in a housing which is vertically positionably with respect to the mower housing. The housing includes a stationary helical flight and a seal guard which fits within the ground roller. The stationary sleeve bearing is protected on either end from dirt and debris getting between the inside surface of the stationary sleeve bearing and the outside surface of the mounting shafts on either end of the ground roller.
