FWIW - I think I have owned three of those 3-point shredders that you show. I found it frustrating that all were built with those metal straps, for if the tail wheel was forced up, say going through a ditch, the straps are unforgiving and are forced to bend. Because I am good at customizing when there is a need, on all of my mowers I cut out a 18"-24" piece in the center of each strap and welded a chain in it's place. Had to be very careful to ensure both sides were the same length. By making the change, the tail wheel easily floats with ground changes, the tail of the mower can be tilted as much as 45 degrees up without a problem, and the chain tension allows the deck to be lifted when I raise the 3-point.
