The 1863 was designed to use a Cat."0" 3 point hitch which will accept some tillers and disc attachments, as well as many other implements. There is also a sleeve hitch adapter (A-frame) which allows you to use the sleeve hitch type attachments.
I hope Kraig will pop in here with a pic or two. He can illustrate the item much better than I describe it. I would look to Xtreme Motorworks, one of the fine sponsors of this site, for more information. They make an excellent 3 pt. hitch kit as well as attachments, including the sleeve hitch adapter I mentioned. Simply click on the colorful links above for their website.
