I have a Walker Model C, 16hp, 42" GHS. I have alot of problems with this mower. New engine at 140 hours, now a new hydro at 150 hrs. I love the cut and how it operates, and the way it handles the clippings in the hopper, and the way it sucks the leaves in the fall. My lawn is 1 acre. 1 small hill, a sand mound, other then that pretty flat, slight slope on one side. I have a Hustler dealer near me, I looked at the Fastrack before , never used one thow. How would the 18hp 52" compare with what I have now. What can i do to see no clippings the way the walker mows? Would mulching deck/blades do the same thing as the Walker GHS or is side discharge ok? What about the fall leaves , what type of bagger attachment is available for fall leave clean up? Thank you.
