Howdy and welcome… I just joined myself.
I still have my fourth Lawn Boy. It's at lest 12 years old with less than three hours running time. It developed a fuel or reed problem and won't start. I've gotten old and lazy so I don't feel like working on it. I just used it to do a little trimming that I now do with a trimmer. I do have the differential with drive axles from a self propelled Lawn Boy that I scrapped many years ago. I thought I might find a use for it.
Have a good one.. Don S..
