I purchased the quick attachment for my John Deere 3 series. The attachment itself fits great. very easy to install. The major problem was the "ears" that lock the rear attachment in place. When you go to unhook, the "ears" don't return all the way in to make it flush, which doesn't allow the attachment to be released. I even looked up reviews online to see if I did something wrong and I found a few reviews and videos of people having the same issue. Had to spend a few hours grinding down the metal "ears" about 1/4" to allow the rear attachment to be released. Once that was completed and spray painted to match, now it works how its supposed to.
