I no longer have my Yanmar, as I traded it in on a 4110 John Deere, I guess about 3 months ago or so. And the Deere has the same sway chain hook up as the Yanmar had. No difference at all, and it works for them, and it worked for me, on the Yanmar. I think you are doing something wrong, for it not to work. John Deere would have them change it on the ones that Yanmar makes for them, if it was a problem.
