Your original post was not directed any one person since you did not include a quote...it was a broad sweeping comment that you stated as fact.
Nice try. Mine was the third post and used the pronoun "you" so was obviously responding to the OP. Choosing to read it as "everyone" was your choice.
The OP stated that he/she has several different implements to attach to the tractor. It is a fact that some implements are not made to exactly match the tolerances of a particular frame-style hitch. You found that out as fact since you had to modify several implements to fit your Deere quick hitch according to your own words.
In my second post (#18), details of why disappointment was likely were explained.
Nevertheless, there is no point in engaging in a pi$$ing contest with you. You are happy with you setup and that is the bottom line. My point is that the OP will most likely be happy with a quick hitch system that can conform to a variety of different implements that may not be constructed to the specific standards required by frame-style quick hitches.
As far as "disappointment" is concerned, it is very likely that you were pleased with the implements that fit right up to your quick hitch and "less pleased" with those that did not. It is a matter of semantics.
And yes, I have owned and used a couple of frame-style quick hitches. Also owned are a variety of implements, some home-made, that do not conform to standard measures. Rather than modify them all, the simple fix of using the Pat's system was chosen.
BTW, I try not to quote unless necessary to save bandwidth and clutter (like this lengthy post turned out to be).
Done.
