Cutting one of my biggest property's(race track) on Saturday i had a small problem. They use rope to block off area's and while cutting along this rope i had to make a turn back. All of a sudden my blades shut down and i see the rope swinging some, go to engage the blade and the button is gone! Rope got hold of it and when i turned it ripped it off. Not even a 1/4 way done and this needs to finished today. Thank god my WB, uses the same switch as the rider and ten min. later i was cutting like it never happen to me. Thank god for universal switches, save my a$$. You never know when you will need a spare mower even if it is for parts.
