I personally have only used a Swisher 60". Not putting them down by any means just saying it was not what I expected. Way under powered for what I was trying to do. Same complaint from many other people who have tried them in my area. I pulled mine with a 102 Cub Cadet and most time the Swisher determined how fast I could drive. Like the way it handled around tress and such, but need something heavier duty. I have upgraded to the 35hp Cat powered Bad Boy and probably don't need it but it would make even faster mowing and I wouldn't have to find a second person to help me. Plus I think it would be cheaper than a Zero turn. 2 huge pluses for me.
