In the interest of starting the new year on the right foot and sharing some mistakes that happened to me in 2006, I'm going to start this thread with several mistakes that I made. I wish everyone health, wealth, and happiness in 2007: 1. Keep BOTH hands on the hedge trimmer when it's running at all times. (Lesson learned - 6 stitches on my left knee) 2. Steep hills are for walk behinds, string trimmers, or for growing ground cover. (Lesson learned - ZTR mowers will slide downhill at a rate of speed twice that at which you have the ability to jump off) 3. A 48" deck (or 60" or 52" or whatever) means exactly that. Don't try to squeeze the mower between the work truck and a wall. (Lesson learned - new front left tire on work truck where the mower blades cut through the tire) While each of these incidents are embarrassing to me I hope that others can learn from my errors.
