I believe this mower was brought into the Hustler lineup for a specialized market purpose, are you at will to say which market? I personally would think this mower best suited to smooth, large open manicured areas. I just can't see a city or county turning their employees loose with a mower of this caliber to cut road ditches and medians.
The 104 is designed to maintain A, B and C turf like you said. Roadside ditches we would consider D type turf which is better suited for a tractor. Example applications would be golf course roughs, parks, sport fields, rural properties or any large areas that are maintained on a regular basis.
