The shop where I work has a job where we use 3/4" plate steel and burn "windows" in it. I purchased some of the cutouts and had them machined by the guy on the machine next to mine. First I made a bracket that I slide on to the front bumper then just hang the weights on it. I have 10 of them and I think they weigh 25# each. I have a B7510 21hp 4x4 hsd they work great to hold the front down! :thumbsup:
