If you post in the future please give all your info in your initial post, like telling us you are just curious if anyone knows. You didn’t provide model number until asked. You didn’t tell us you contacted MTD and got a different model number. You didn’t tell us you had a third model number. I spent a half hour trying to find an answer for you, because I thought you needed it now. I am putting you on my don’t waste your time list for the future. That way I can help those who really have a problem.
