I'm a homeowner with 3/4 acre. I'm considering buying a used 48" hydro Scag Walk Behind and am hoping to get some input. I'm weighing this option against buying a new Fastrack. Any one out there have a pump or hydro motor go out on a Scag? If so after how many hours (read or approximated)? How many hours would you expect a hydro Scag Walk Behind used commercially to have before running into significant problems? What problems have you had with yours and at how many hours? Any suggestions on how to gauge the condition of a used one? Seems like more often then not there is no hourmeter. Thanks for any input.
