My Exmark came with the roll bar and I was determined to get use to it. It was in the way most of the time. Then one day I hung a guy wire off of a telephone pole and the Exmark got to about a 45 degree angle in just a split second. As soon as I got home, off came the roll bar. The first time I took the mower in for tune-up the mech said they were told not to work on any mower with the roll bar removed. I told him I had been wanting to try one of those new Husqvarnas. He started getting his wrenches out. My point is, I think the roll bar will cause more flips than would otherwise happen. Anyone else with similar experiences? Or do you like the roll bar?
