Is the 13hp Kawi on the model S Walker enough for a 42" GHS deck? Or should I go for a model C? Also, can you get the slide in bins for the 6.7 catcher, or only the 9.0 catcher? I am hoping to get one bought here pretty soon if I can get one cheap enough. Either going new or slightly used. Also, if anyone wants a 50 inch Dixon, send me a PM.
