-19- ABSTRACT A self propelled lawn aerating machine includes a plurality of generally vertically reciprocally movable tines operated by a cam shaft for removing plugs of soil from a lawn. The tines are spring biased upwardly and in forward direction toward a bumper board located forward of the tines. When withdrawn from the lawn the tines strike the bumper board with sufficient force to break the soil plugs and cause the resulting loose soil to be scattered over the surface of the lawn as the machine moves along an aerating path. The bumper board has a raised position wherein it supports the tines in an idling position above the surface of the ground while the machine is moved across walkways, driveway, and the like.
