I am currently making a rear ballast “box”. I had an old quick hitch that the previous homeowner left in our barn. It fits on my L2501 three point hitch, but doesn’t fit my rotary cutter. I made a form of wood, and am filling it with concrete around the quick hitch. It will use four 60 lb. bags of Quickcrete to fill the form. So when done, I should have a rear “box” ballast the weighs 240 lbs. plus the 35 lbs of the quick hitch. Pics when it’s done.
