I am in the market for a new mower. I am concidering the Dixie Chopper, but also the Kubota ZD if I could find one in my price range used. I do some commercial mowing, but will be cutting a lot of pastures/fields with this new mower. I know the Dixie Chopper has the fastest blade speed, and am pretty confident it will do quite well with the fields if the height is within reason, but would the Kubota possibly be a better choice. I want this mower to last, and be reliable because it will not be just cutting nice grass. I plan to buy one with a 52'-60' deck. Would it be obsurd to even concider a chopper over the diesel aside from price, or because of the field mowing is it reasonable?
