Wow, looks like an interesting project. :welcome: to TBN! I am kinda a simplicity nut too, I have a Simplicity 9518 tractor that I have been working on for over a year, it is my mechanical rainy day project. It is a Diesel, there are some 5 or 6 versions of it through different brands. i love the simplicity garden tractors, one of these days when I get my 9518 running again i am gonna go get another simplicity, fun little machines to work on. :thumbsup: Here's a picture of my 9518, I added a set of ROPS to it and fabricated a bracket that attaches them to the axle for support. :thumbsup:
