Custom 3 Point Weight Bracket

[Powereng]

Since I got my Kubota with FEL I discovered how much I need to get some weight on the back of the tractor. I've been torn between purchasing a ballast box vs. some kind of suitcase weight system. When I was home this weekend cleaning out the family farm I picked up some 140# JD wheel weights. I have an idea for 3 point hitch weight bracket where the round wheel weights could be mounted. Sort of like a Heavy Hitch 3pt receiver hitch bracket but with a post coming out the front that the weights could be load onto. When I get back to the office on Monday I plan to draw something up in CAD. However just curious if any of you guy have fab'd up something similar or know of something commercially available. Attached is a picture of the weights.

Thanks, Powereng
