I need another mower for this year, so I have narrowed down the choices to a few units. The Grasshopper is 61" with 27 hp and costs $8700 without a bagger; it has been sitting out all winter and is very dirty and has some rust. One of the Hustlers is a regular z with a 60" deck and 25 hp; it costs 9100 with the triple bagger, is in very good condition, but was a demo and has around 50 hours. The other Hustler is a super z with a 60" deck and 31 hp; it costs 8500 without the bagger, is in very good condition, but was also a demo and also has around 50 hours. I mow Kentucky Blue Grass primarily; would a Hustler with a bagger do well on this type of turf? I have heard bad things about their cut quality on northern grasses. I need a bagger on any of the mowers, so the Grasshopper and super z would cost more than the regular z that comes with a bagger.
