I have a 2001 Husqvarna ZTH-6125 zero turn mower that I bought new. It is now 25 years old. My only wish is that I had bought it 10 years earlier.
The deck is adjustable from 3 to 6 inches (IIRC) and with sharp blades and the deck height set to 3 inches it will cut 12 inch high DRY grass with ease, even with its 61 inch cut. It will cut wet grass well, but not as smoothly as dry grass.
The beginning of the second season I had to replace all the hydraulic lines, as they leaked at the ferrules. Poor design on the part of Husqvarna. One coil went bad just last year, I replaced both with new Kawasaki units. Other than that, just maintenance items. The engine burns no oil.
For all but the last 3 years I cut 10 acres of grass weekly. The mower cut my time in the seat in half compared to a tractor and bush hog. Push mowing/weed eating is near zero because you can cut that close.
