A soil aeration apparatus (10) may include aeration tines (50) that are actuated by a relatively compact gear system (60) that reduces the size and weight of the apparatus (10). In addition, a soil aeration apparatus (10) may operate without a centrally disposed support shaft, thus enabling the tine-holder shafts (30, 40) to be positioned closer to one another and reducing the size of the apparatus (10).
