Hey thank you for that. I am a fitter and turner by trade so I have a fare bit of mechanical exposure. I have never had anything to do with ride on mowers. So this is a new experience for me. I have changed the pulleys like suggested. However, I noticed in your pic that there are springs on the inside of the pulleys. I only have the one spring that looks to be the same size. Are these common springs that I can get from a mower shop and is there more parts behind the pulleys?
