Patent ID: 8424613

Claim:
An aerator attachment for zero turn lawn equipment having a forward end portion and a forward frame the aerator attachment comprising: a mounting means adapted to attach to the zero turn lawn equipment such that the means for attachment is pivotal about an axis that is generally parallel to the ground; a cross frame assembly pivotally connected to the mounting means such that the cross frame assembly is pivotal about an axis that is generally parallel to the ground, the cross frame assembly comprising at least one first frame member and a second frame member attached perpendicularly to each other; wherein the first frame member is pivotally attached to the mounting means such that it is pivotal about an axis that is generally parallel to the ground; at least one caster assembly, each fully rotatable in 360 degrees and reversible without requiring disengagement from the ground and independently mounted onto the second frame member of the cross frame assembly, the at least one caster assembly rotatable about an axis that is generally perpendicular to the ground when the attachment is engaged, the at least one caster assembly comprising a means for retaining at least one tine rotor assembly fully rotatable thereon; and an adjustable actuating mechanism comprising an extendible arm with two legs, the first leg being pivotally connected through the mounting means to the forward end of the lawn equipment about an axis that is generally parallel to the ground and the second leg pivotally connected to the second frame member of the cross frame assembly about an axis that is generally parallel to the ground, the actuating mechanism mounted such that when the tine rotor assemblies are engaged the front end of the lawn equipment is adjustably at least partially lifted off the ground to allow adjustable depth penetration by the tine rotor assemblies.
