Just a quick word to the newbies and a reminder for those that have been mowing awhile. Watch out for the heavy frost and do not run the mowers on it! I speak from experience...last year I mowed a highly visible lawn while it was heavily frosted. I had done it before and had no problems, but this time it left these nasty brown (damaged grass) streaks everywhere the Walker went. I was never so happy to see the rest of the grass go dormant and turn brown. It took about a month and every time I drove by I was reminded of my stupid mistake. I won't be making that mistake this year.
