Marty, I do not know who makes NH loaders, but I suspect NH does. There are many 3rd party loaders. Perhaps Woods is the best known brand and I know of several more. Look through the posts on this board (don't limit yourself to NH discussions). Also, you could use the search feature to look for "FEL" or other variations of terminology. Good Luck. NH currently does not make a quick-attach bucket, but I think Woods does.
