I just purchased a 20/52 Fastrak last Friday to mow my 4 acres. I was surprised by the quality of cut and power that the Fastrak has. Upgrading from a Murray (don't laugh) never felt so good!! I also purchased the hour meter and seat spring kit (did some research on the Internet before purchasing the mower) and it really makes for the smooth ride. I also have a few questions: 1. Does anyone offer a canopy to put on the Fastrak? Most of my mowing is out in the open and it would be nice to have a little shade. 2. How hard is it to change the mower blades on the Fastrak? Any tips for a Hustler noobie? Also, I've read about regular blades, hi lift blades and gator blades. What should I be mowing with?
