Same here. Mine is fully stocked with 16 42-pounders pretty much at all times. I've been looking for some 70-lb. weights myself to swap in there, but can't find them either. I love the compact form factor of the HH, and having the cart & casters is a big help moving it around when I don't have it on the tractor. I'm also keeping an eye on the new add-ons they are making for it, specifically the landscape rake & back blade. I don't have either of those implements, so adding the functionality of both at basically the cost of one is pretty intriguing.I think it's great - easily move 600lbs and depending on what I'm doing with the ballast/tractor don't always take it off when it's on the 3pt.
