Turf aeration device

An improved method of aeration, consisting of attaching a turf aeration device to a pulling vehicle, where said turf aeration device comprises a frame having a drive shaft, wherein said frame is attachable to a pulling vehicle having a power take-off portion;

• where the device has a power transfer means, operatively attachable between said drive shaft and said power take-off portion, for transferring power from said power take-off portion to said drive shaft;
• and a plurality of aerator mechanisms operatively attached to said drive shaft and said frame, each said aerator mechanism comprising a lower link member, having a base end and a distal end, wherein said base end is pivotally attached to said frame;
• a tine holder, adapted to hold at least one tine, pivotally attached to said distal end of said lower link member, a roller frame rigidly attached to said frame, said roller frame having a rolling means positioned for ground contact when said turf aeration device is deployed in an operating position, and a means to allow limited rotation of the aeration device toward or away from the pulling device, whereby said means to allow limited rotation allows said rolling means to automatically adjust in response to ground contours when said turf aeration device is deployed in an operating position thereby rotating said frame toward or away from an attached pulling vehicle, said method further comprising the steps of installing tines in said tine holders, positioning said turf aeration device on the ground, and moving forward, pulling said turf aeration device across the ground.
