Just about to buy a John Deere tractor 120 series. Stopped in to my local Hustler dealer and saw the Fastrak 44 18HP Honda. I only mow a 1/2 acre, but believe in buying quality and buying it once. Is it worth it for a home owner to spend double the price of the JD for this unit? What can I expect for a life span and maint. cost over a riding unit costing half as much. I have some experience with Scags and Bobcat equipment, how does the Hustler quality compare? Thanks!
