I am thinking about a larger ztr or wright stander 48 rh for later this year. I am comparing the Zs. In terms of reliability and performance which is better? The scag tiger cub 19kaw 48 velocity or exmark lazer hp 19kaw 46 triton. Which deck cuts better and is better at mulching down here in louisiana? Is the 19 kawasaki enough power? Any feedback on which would be best is apreciated.
