Man, not what I found when I was researching for mowers. Husqvarna was one of the better Lawn Tractors. As far as tranny goes, mine is a K57R Tuff Torq which is beefed up version from there K46. I actually haven't mowed yet but as far as driving around the yard I think it's a very tight mower.
Cub was not rated as well, I'm just say'n.
