I believe the wheel height adjustment arm is the main problem with the grinding of the wheel gears. I proved this by fixing my Lawn Boy Self Propelled mower years ago. I simply installed a correct thickness stop spacer directly behind the wheel mounting bolt. Here is a video of my fix. Hope it helps someone else. https://www.youtube.com/watch?v=og8gIZkAvzo
