Checked out the Hustler FasTrak Super Duty 48"; dealer network is weak in my area compared to others, but a nice machine and a contender as I try to decide.
Will add mulch kit for full time mulching (thick bluegrass blend). Under one flat acre with lot's of landscape beds / inside and outside curves. Cut quality very important.
My current options at similar pricing:
Scag Freedom Z (48") with 20HP Kawasaki
Hustler FasTrak SD (48") with 23HP Kawasaki (will also add Flex Forks)
Toro Titan MX4880 with 22HP Kawasaki
The budget option:
Toro ZX4820 with 22HP Kawasaki
The Hustler is looking strong because of the added HP since I'll be mulching, but Freedom Z seems comparable beyond HP, maybe a better mulching system.
