You can see just how sharp our fairway mowers are! This isn't too good for the mower. In this case, I am sure someone just accidentally lost this out of their pocket. However, if the lightening alarm goes off, please mark your ball with something that, if you don't return, won't harm a mower. An example would be a tee or a plastic ball marker. Anything metal is not good because if the operator doesn't see it and it goes through one of our precision cutting units, down time will result.
