tillerman 0 Posted August 1, 2005 Rick if you click on simple tractors at the top of this page, then go to parts and manuals ,then click on belt reference. That will tell you what length of belt you want. Works for me. Good luck. Richard Share this post Link to post Share on other sites
tillerman 0 Posted August 1, 2005 This may not work because there is no simplicity equivalent to the 300 and 400 series AC tractors. Share this post Link to post Share on other sites
