I know it makes sense to use a timing belt! But all the successful reduction systems use a v belt! I hear that at an idle the belts get destroyed quickly. There must be a reason why they use a v belt instead. Maybe if the propeller hits grass or bugs in the air it could destroy the belt. But if that was the case what about the old sunbeam lawnmower! With the 2 blades cutting grass with timing belt’s, and an electric motor in between! I had one and it went threw belts at least once a year. Maybe that’s why lawn tractors use v belts and they last a long time. If any one knows why let me know. I still haven’t heard from gates belts I think I will have to email them. again
