Greetings!! I really need some help selecting a new mower 46-48" cut in the $2000 range.I have right at 2 acres to cut and my current mower is a 14 year old Craftsman 42" with a great running Kohler Command 15.5 but the deck is thinning,needs new tires ect,it has served me well. I know from experience that the Kohler Command is a durable motor. I was looking at the Cub Cadet 1000 series,some have the single Kohler Courage,twin and the twin Kawasaki,I've heard some bad in the past on the single cylinder Courage motors but not much on the twins,the other mower I like is a Snapper SPX 22/46,it has the B&S Professional series twin on it. It would be great if I could find a residential mower like what I have with a Kohler Command but have not found one.I'm leaning toward a Cub Cadet but which motor is the most durable.Any other mowers recommended? I do plan on buying from a dealer and not a box store.I take really good care of my equpiment which is a big part on the life of the mower but some engines are better than others.My concern revolves around the heart of the mower "the motor"
