I received mine Friday. I was happy to find that there was no problem with the draw bar attachment. It fit perfectly over the draw bar arms. The problem was that the width was a bit too narrow to go over the pins of my implements (a box blade and a rear blade). Both implements were the same spacing, but the H.F. quick hitch was a bit narrower. Maybe 1/4 to 1/2 inch. I used a floor jack and a length of 4x4 to spread the quick hitch arms a tad. It was easy to do. Ends up distorting the quick hitch a bit, but doesn't affect the functionality any. First problem fixed.
Next problem: The lower hooks would not go onto my box blade due to the thickness of the hooks. They hitt some brackets on the box blade. I had to take a hack saw to the box blade and trim about a half inch off the bracket. Worked up a good sweat and got the bracket trimmed back to where the hooks on the quick hitch would fit. Problem two solved. The quick hitch now fit nicely on my box blade, except that the top hook doesn't have enough clearance to just hook under the top pin on the box blade. I have to pull the top pin on the box blade, position the hook on the quick hitch, and slide the top pin into the box blade, through the hook on the hitch. Not as "quick" as it should be, but still an improvement. At least I don't have to wrestle with the bottom pins to attach the box blade.
Problem three. The top pin of my rear blade has even less clearance for the top hook on the H.F. quick hitch. There's no way the hook will fit. I will need to order the "adapter" from H.F. Then both of my implements will fit nicely.
Problem four. Tried to order the adapter from H.F. Was told that they were on back order 'till August 4th. And since they cost less than $10, I can't order one 'till they are in stock. So I guess I have to wait 'till August 4th and try again to order one.
Once I get the adapter, the quick hitch should work pretty well with the two implements I have.
By the way, the swell web page that lets you review your order on H.F. still shows that mine has not shipped yet and is still on back order....
