I just built a front weight ballast box for my JD 3032E. It is built out of 2 inch angle iron and mounts to a 2 inch reciever hitch that I added to the front of the tractor. The box will hold 14 - 4 " x 8" x 16" solid concrete blocks for a total of 350 lbs. You can add more blocks to it also for more weight if you used a ratchet strap to hold them in place. Each block weighs 25 lbs. I will post some pictures of the build soon.
