Husqvarna- best lawnmower I've owned. It's an all wheel drive model. They cost a bit more up front but it was worth it not to have to push a mower through the thick wet grass we get down south.. That thing pulls me!
Have a 24hp Husqvarna rider and no problems. My wife and I live on a farm with about 2 acres two mow and still have the main drive belt on. Only thing I have changed out is the battery. People say it still looks new.
