A friend of mine in the Lawn Care business has a 60 inch Lazer that has to be at least 6 or 7 years old. I asked him yesterday how many hours on it and he said over 1000. How many belts I asked him did he replace. He said none. All are the original belts. What is the normal belt life on these machines when properly maintained? 1000 hrs seems like a lot to me.
