Does anyone know if there is a dump from the seat grass collection system for a Ferris IS3000? I checked there website and all they have is a 2 and 3 bag unit that you have to get off and dump. I was looking for something similar to what you see on a grasshopper or dixie chopper. I have the brocure from when I purchased my machine and its shown there however the dealership doesnt seem to acknoledge that it was once available. I was curious if anyone knew if they still existed or if there was a aftermarket alternative?
