I bought a used GT5000 last weekend. I brought it home and cleaned it all up. It's got a B/S 22HP motor and a 50" deck. Problem is I can't find a rear bagger that fits it. I called Sears customer service and they told me a rear bagger was never designed for this model!!!! Has anyone ever had any luck modifiying a 42" or 54" 3 big bagger before?
