available for the Navigator? I am in desperate need of additional mowers, and would rather have my tractor units running three extra days per week than purchasing a new stand on or rider. What really aggravates the living crap outta me was the line of bs I swallowed when buying the Navigator last year - believing that a side discharge deck would be available and with in a year. Well, it has been eighteen months now and no one seems to know when a side discharge deck is going to be available. Anyone try adapting a Walker side discharge deck to a Navigator?
