Danny, another thought about your post. What is the spacing on your pins on the KK rake? On my blade, it is about 30". Most of my other implements are between 22 and 24.
What I found with Pats, and others have referred to it here but I just didn't comprehend what they were saying, is that if you set your Pat's alignment to fit with a 24 inch spacing, you cannot back up to one with a 30" and have it align. Obviously, you have to spread the lift arms, which is no big deal.
But do this simple test. With your lift arms set at 24", align the ball (or Pat's) to be square with the pin. Now slide one arm out another 3" or so, to simulate the wider implement. You will notice that the ball (or Pat's) is now so out of angle that a pin would not go in it. Of course, with Pat's, you can adjust the alignment, but that kinda defeats the benefits of having Pat's.....
I still like the system, only now I am MUCH smarter and will check the size of any new implement I buy or will make sure I can successfully mod a used one to have 24" spacing on my pins.
Hope this clarifies.
