You posted in the Announcements forum that you could not find a thread that Lawrence Stone posted about his tow aerator, so I figured I would post it here so others will be more likely to see this and learn how to search for a specific post. I went to search and typed in aerator as the Key Word and lawrence stone as the user name of what you are searching for. It has to be in lower case since his screen name is in lower case. Click on Perform Search and you will get several threads. This is the one you want. http://www.lawnsite.com/showthread.php?s=&threadid=11871&highlight=aerator I hope this helps.
