When I was shopping for my tractor, a friend of mine offered to give me his ballast box -- no charge. He didn't really like it. I didn't like it either. So I started looking for another solution.
I already had some suitcase weights left over from my previous tractor. So I decided to build on that and use Heavy Hitch's products for managing my ballast. I think their solutions provide a lot of flexibility and efficiency. I've used them to provide me with fast changeouts of ballast with minimal effort.
The attached pictures attempt to show my ballast system. Since I've had some trouble getting images posted in the right order, I numbered them. They make more sense if you look at them in order.
