Is anyone using Pats QH with a KK 48" tiller? It looks like it would be a very tight fit, but might make it.
You may be using 2 different hitch names together.
Pat's is the Easy Change, just see the ads on this site. No reason the KK tiller , or any other Cat-1 device wouldn't fit using Pat's. (I have the 48" KK tiller, by the way).
The QH, or the Quick Hitch differs from Pat's system. It's the big bulky steel frame that you semi-permanently mount to your existing 3PH.
I am using the Quick Hitch I procured from HarborFreight. You are right, it is a tight fit with the KKII 48" gear drive tiller.
A lot of folks, including me, used a bottle jack to spread the lower coupling points on the QH, in order to fit some of the implements that were just a hair too wide at the pins. I had to spread mine, at most, about 1/2".
Pat's system allows you to still use the lateral swing you have in your lower linkage arms, allowing for a wider variety of widths of implement pins.
Pat will stop by this thread and correct me if I have mis-spoken.
The QH is the cheaper way to go, but, it also has some inherant issues that you may have to deal with, like the lower-pin-width issue.
