Okay. I believe I figured it out.
And, Mike, it does make short work of hooking up the MX6. If only the @#$% knuckle on the PTO shaft would hook up easier then I'd be set.
It looks like the Frontier Box Blade, ballast box, and even the Buehler Farm King Finish mower will fit fine. If they connect that easily then I should be in great shape.
Note to JD - put different cotter pins on those units. The flip type with the smaller shank works better and you don't need a pliers to ratchet the little buggers off!
I'll check out the manuals and see what they have to say - otherwise I'm pretty impressed with it. Probably saved my back and bad neck discs alot of hassle by having it, too.
Thanks for everyone's help!
