Im having a hard time finding the connection kit to turn my Ryan core aerator from a pull behind unit to a 3pt. hitch unit to pull behind my tractor. My dealer who sold me this aerator knows nothing about this kit. But I have seen it on here from other scapers and 2-3 years ago I rented a 3pt. hitch version on my aerator. Im not sure of the model of this unit but its the really heavy pull behind unit with all the spoons are attached to the weighted metal disks.
