We believe that you should cut your sod after about three weeks. It will be long and possibly wet. In order to make it as easy as possible to cut, we think it is a good idea to turn your sprinklers off a few days before you are going to cut it. Wet grass never cuts well.
We also would like you to use a small mower (NO RIDERS) and mulch the grass the first cut and bag it the second time you go over it. Yes, we want you to cut the grass two times the first time you cut it.
