Ken, I might be wrong but I think what the OP was getting at was the mower was able to flex (tilt) from side to side. Most all mowers can tilt from front to back. Go to the link of the kingkutter mower he provided in his 2nd post and study that picture closely. Especially those two small zinc plated hinges where the A-frame for the top link attaches to the mntg brackets on the mower deck. I'm also guessing there may be some sort of a swivel joint under that hood where the two bars join (that pull up the rear of the mower deck). I think all that is what lets the A-frame tilt side to side. I've never seen this in person so like I said, I could be wrong about it.
