Tim, the attachment is a photo of one of the pins from my YM1110D. I loaned my tractor and tiller to a friend for a summer, and he lost one. I have never replaced it. If you like, I can take some measurements for you so you can have some made, or try to get some from a dealer. The pins for my YM1301D work on my YM1110D, but the larger diameter section is longer so they stick out a little bit.
