I am thinking of putting something on my tractor to carry tools and saw. I need to find something that will hold about as much as can fit into one of those large plastic rubbermaid totes. I was using one of those to put my saw, chain oil, small mixed fuel gas can, chaps, etc. in and would bungy it down to the seat on the backhoe behind operator seat. But this is not sturdy enough and I will not be doing any longer for fear of having it come off and dumping everything. Any ideas let me know.
