What to order with it really depends on what you plan to use it for aside from mowing, maintaining manure piles and moving bedding etc.
With the BH I assume you have some stumping to do, or plan to have. If you plan to harvest some of the wood off your lot, or if your property has a particularly long drive or entryway for snow removal, or if you plan to use ground engaging equipment for food plots, search this site for advice given by people who have written about what works best for them, or what hasn't worked. Too many details to list in a single post but there is a lot to learn by reading about the experiences of others.
You've chosen a very capable tractor, there are many different implements / attachments that you can use with it. Let us know what you decide, some of us live vicariously through those who are doing what we wish we could. :thumbsup:
