I researched the hell out of ZTRs before making my last purchase. Ended up with a Dixon Ultra 60" which is their middle of the line light commercial/heavy residential. It's a twin to a Husqvarna with the exceptions of a much better seat and a different mechanism to raise and lower the deck. It was the best I could find for the money. Paid $5k for it about 8 years ago.
Everything I learned about ZTRs:
ZTR's are not the best choice if you have a lot of hills.
Heavier models are better on hills.
If you have a lot of trees, you can't afford NOT to have a ZTR.
If you have rough ground, most all beat the **** out of you. A heavier mower is better.
If you have rough ground, buy a Ferris. It's the only one that offers full suspension.
Full suspension makes a Ferris a poor choice for hills and ditches.
Most important is what size hydraulic pumps they use. Find one that uses the larger commercial pumps, They will last much longer and offer a higher top speed.
Wider decks scalp more than narrower decks.
A center mounted deck is more maneuverable, but an out front deck is better at getting under bushes and into corners.
The engine and pump setup are far more important than whether the deck is stamped or fabricated. Stamped decks offer better aerodynamics for grass discharge, but in the end it's metal thickness that determines durability.
If you ever want to add an aftermarket snow blade such as the one made by Swisher, make sure the way the front end is designed in a way that will accept it.
Some engines are better than others. Some models have multiple engine options.
Most all are made from standard industry components. There's a lot of interchangability of parts.
There are forums out there for landscape professionals that discuss every facet of ZTRs extensively. They'll tell you what's good and what's not.
Hope this helps!
