Hello, I just purchased a 20/52 Hustler Fastrak this year, and am very happy with the quality and power. However, the factory blades seem to leave alot of uncut pieces of grass. I would like to try the mulch kit and/or gator blades. Can someone tell me the best place to find these parts? What does the mulch kit actually consist of? My only other thing I would like to add is a spring seat, the factory one is a real kidney shocker over bumps. Where can I buy Fastrak accessories? Thanks in advance.
