hey guys I have a quick question.... Yesterday I decided to get my dads 129 out. Took me about a half hour to fire up... sounded good so I thought I would try mowing with it... oh boy didnt take long before I realized that the blades were shot... Question is how can I determine what deck size I have on this old girl so I can get new blades....I always thought that it was a 42 in but im just not sure.
