The least you should be doing is trimming around the heads and making sure there is no thatch down there, holding the heads from sealing. Yes, they should be raised, especially if they are 4 inchers, one reason I use 6" in turf. That being said, one of my sites that is going on 9 years is going to get some serious raising next year! Swing joints rule.
