ABSTRACT:
A soil aeration apparatus may include aeration tines that are actuated by a relatively compact gear system that reduces the size and weight of the apparatus. In addition, a soil aeration apparatus may operate without a centrally disposed support shaft, thus enabling the tine-holder shafts to be positioned closer to one another and reducing the size of the apparatus.
