I could use some good ammo in the form of general information to give my customers when they ask why I have raised the mower decks at the beginning of July. I usually give them the basic "So the lawn stays healthy and doesn't burn up too quickly in a period of dry weather" What other reasons can I put in my arsenal??? I live in Central Indiana. Lots of different grasses. I would say mostly say bluegrass. Thanks to all in advance!!!!!
