I mounted two hardened steel all-thread rods on my front bumper (7" in length). Then I had corresponding holes drilled in three 2" thick solid steel stock (2" thick x 6" wide x 15" long, about 75 pounds each). I slip each steel plate over the bolt studs and then fasten the whole thing together with a flat washer and nut. Kinda takes a little time to set it up, but I found the steel stock sitting out back of a welding shop (scrap pile). With the cost of the bolts and paying them to drill the holes, I have about $50 into 225 pounds of front weights. Besides, I just leave then on, except during mowing season.
