Highly recommend putting fluid in your rear tires if you haven't already done so.  That will add a couple hundred lbs.  Your 3 pt will lift about 600 lbs at 24" behind the lift arms, but most implements used on a BX are lighter than that.  I've found a 400 lb. box blade works well as counter weight and it's a useful implement as well.  That's probably a good weight for a ballast on the 3 pt... maybe more if you don't do the tires.
