I have a Great Dane 61" Super Surfer. These are no longer available. I will use it till I retire. I have a ztr, a front deck, and a walk behind, as well as my stander. If Wright made a stander with a diesel engine, I could sell three mowers and buy one. Before buying any new mower, I would check out the service dept and how they handle warranty repairs and loaners. I would go to the landscaping expo in Louisville Kentucky which is in October each year and get a price quote directly from the manufacturer.
Then take that quote to your local dealer. It will save you thousands, I'll say that again, THOUSANDS of dollars.
