Perhaps someone can help me understand this. I can see how the quick attach works on blades and stationary equipment. The lower pins lock and the upper mount rests in a hook. How exactly does that work in the instance of a 3 point mower where the top mount pivots to allow the deck to float? I can't imagine it staying in that hook. Is there an additional adapter needed to keep it attached or does luck hold it in place? I can see a nice improvement in hooking up the box blade or ballast box but the mower I can't quite figure out.
