ABSTRACT:
An aerator device for attachment to the front end of a power riding lawn mower has two features which enable a spiked roller assembly to guide itself smoothly through a desired path and to make turns without excessive digging in of the spikes. The roller assembly includes a plurality, and preferably three, of rollers disposed coaxially on a shaft with each roller being rotatable independently of the others, facilitating turning. Self-tracking of the rollers on a desired path is provided by vertical mounting of a pivot pin connected to the roller assembly in a journal supported by a frame forward of the roller axis. The roller assembly pivots to follow the frame journal without operator intervention when propelled forward.
