I have an embarrassing story. I was mowing a yard last summer for a friend(he was in a wreck and unable to do it himself) The front yard has a slope down towards a ditch. The ditch is very shallow but steep sloped. I was going to make one more pass on the bank with my ZTR and then finish it with a pusher. The grass was wet and it started sliding down the hill. I tried to stop it but it was no use. I slid down to the ditch and the deck dug in. I turned the mower towards the road to drive out and the rear bumper bottomed out leaving the tires spinning in the air. I had to get my truck out in the street totally blocking the road. I only had some pull type tiedowns in the truck. Keep in mind this is a 1100 lb mower. I hooked the only 2 straps I had to the mower and broke one of them trying to pull it out. Boy did I look like a real professional!!!!
