I found a piece of 8" steel pipe, 28 1/2" long with 3/8" thick walls. I am thinking of cutting it in half to make two weights. Filled with concrete they should weigh about 80# each. For the front I will keep it simple and make a bracket. For the back it gets more complex as I have a sleeve hitch and a PTO. Any harm in supporting 160# on the sleeve hitch while running a snowcaster?
