I built some wooden weedwacker holders about four years ago. They work well, but I am gonna upgrade and make some out of steel. I think I will use like 1" square tubing for the uprights, and custom fab some holders to latch around the wacker on its handle and opposite side. I think I will make mine to hold three wackers, and bolt on to the base of the trailer. I know they sell these for as cheap as $100, but I will probably only have to buy like maybe $20 worth of steel, and I have the rest myself. I will actually have some downtime in a few weeks, so I figure I can keep busy for a while making these.
