I sold my Cub Cadet RZT 42. That had to be the roughest riding lown mower I ever owned. Uncle Arther affects my lower back and that mower didn't help the cause any. I don't have anything against Cub Cadet but that one just didn't do it for me. I went back to a tractor type which rides better. I don't know if all zero turn mowers ride like that or not but I've noticed others that appeared that way.
