hoeman does make a good point but even if you need some modification for a particular implement you only have to do that once. I have a bushhog rotary cutter, woods rake, woods backblade, and a no name box blade. Only the box needed some tweaking, everything else fit fine. (The top link connection point can be pinned at different heights). My box blade had to have some metal cut away to allow the lower arm to access the pins)
