I have a drag behind harrow that I weigh down with whatever on my gravel drive. It is great for summer weeds, some leveling, and today to finally break up the 2 Inches of solid ice. As you can imagine, the weights fall off. I am looking for the weight per ft for some 3' long beams that I can weld on the front and chain to the middle or back. I am looking for eighty pounds per beam. My driveway is 1/10 of a mile, and yes, it tears up the yard when I turn around, but weeds grow back. I use my jeep in 4 low to pull.
