I bought what I thought was a jd 300 backhoe. It had jd 300 on the loader arms. But now I found a tag on the back right of the tractor portion that says 300-b so I'm confused
Post up some pics for us to help you id the hoe.. and should be a tag with model and s/n, if that is the tag you say has you confused. Pics of these things will help answer your questions..
