Certainly don't mine post of my former 2210. But I will say, the box in the picture above is 280 lbs, 100 lbs of wheels weights, and 140 lbs of clip-ons and I have found it to be well suited for ballast for 97% of my use (gravel, sand, or whatever). Whenever I need more weight for moving heavier material, I just put two 75lb sand tubes across the box.
