The item you are viewing is a John Deere 48" Tow Behind Aerator. It is the largest Aerator for towing behind a lawn tractor, with a wheel base of 58" and an aerator system of 12- four point aerator hole points. The actual aerator is 48" with a weight bed of about 49" by 18", large enough for 5 solid cinder blocks. The unit was purchased last August and has only been used one time. It is like Brand New!
