I don't understand the not moving from side to side, I have a set of Pats Quick Hitch on a bx 2200, with a 5 ft. bush hog, I just went outside and raised the mower, and removed the pins from the telescoping stabilizer links and the mower will move from side to side, with no restrictions. The lift arms move on the balls at the front of the lift arms with no restrictions from the quick hitch. If you could see the entire system you would see that it is well thought out and works flawlessly. The Quick Hitch has been modified (improved) from the ones pictured on the site, with the arms set at the correct width, and just below the impliment pins, just back up to the pins and they automatically line up, raise the lift arms and they lock onto the pins automatically. With the bx, it really makes hookup a lot easier. Will post pics later.
