what's the best aerator for, on average 1/3 acre lots. about 20% irrigated properties. some lots are smaller, some a little bigger. i have a $200 pull behind aerator for the 318 john deere which works O.k. but it is difficult on the smaller properties to turn/back up if walk behind is the one you suggest i want one that is easy to handle and turn. i want it to go nice and deep and draw good plugs on hard turf.
