Abstract
A lawn aerator has a series of tine assemblies spaced along a driven shaft driven by a motor. Each fine assembly has a plurality of tines for aeration extending in a substantially radial pattern about the driven shaft. The inner tine assemblies along the middle portion of the driven shaft are secured to the driven shaft to drive the aerator along the lawn as the driven shaft rotates. The outer tine assemblies adjacent to the ends of the driven shaft are rotatably mounted to the driven shaft. This permits the outer tine assemblies to rotate independently and thereby makes the aerator more maneuverable and easier to turn. Removable weights can be attached to either side of the aerator housing to help maintain a straight course when traversing a slope.
