ABSTRACT:
Certain embodiments of the invention include an aerator that provides a shifting means adapted to alter the path of the aeration tines so that they do not impact the ground surface, the shifting being effected without lifting the entire aerator from the ground surface. Some embodiments of an aerator further include an energy modulation system that is capable of relieving a shock to the gear system caused by an aeration tine impacting debris, rocks or a hardened portion in the ground
