Deere has a ballast box that quick attaches on theirs. It is a box that you fill with heavy stuff, and could also hold tools, chains, etc.
I already have a pond scoop, so I am adding weight to it for now...
Lots of folks use a box blade or other heavy implement. You might justify a heavier boxblade which also works better than a light one. You can add weight to the boxblade, too.
My owners manual covers ballasting pretty well, and it pretty much expects you to put ballast in the tires AND a rear balast.
