EXACT: I know what you are saying about productivity. We are a full-service landscape maintenance company with 25 years in business. We have become extremely productive at what we do and hate it if anyone judges our work on how long it took us to do it. I had a Snapper plugger die on me last Fall after about 15 years. As you can guess from 15 years of use, I really haven't done enough aerating in the past to justify the cost of the LS. However, I am believer that if you invest in equipment, you are forced to find work for it. Additionally, I am converting to organic lawn care and aeration is one of the core (haha) organic aids.
