What size box blade?

[Iowachild]

I am looking to purchased a box blade for general leveling and driveway maintenance work. I have a 19 HP tractor that weighs around 2800 to 3000 lbs. with the FEL installed. I have read you should go wide enough to cover width of rear tires. That would require a 5 foot blade. Two questions: Do I have enough tractor for a five footer and what should I look for when buying the blade?
