Who this group is for
The argument here is durability rather than throughput. A fabricated deck takes an impact that dents a stamped one; a serviceable spindle is an hour in the shop rather than a deck replacement. You notice it in year six, not year one.
ZT HD Stealth is newer than the AriensCo line handout this grouping comes from, and is placed here by product category.
How to choose inside it
Start with your acreage
Under an acre, storage matters more than speed. Above three, deck width starts saving real time.
Then measure the gate
It is the hard constraint. The widest deck that clears it is usually the right answer.
Then think about the ground
Trees, beds and slopes reward a narrower, tighter-turning machine over a wide one.
Sorted by the ground they suit, not by price

Common questions
How much mower do I need for two acres?
Most two-acre properties are comfortable on a 42″ to 52″ deck. The gate and the obstacles matter more than the acreage once you are past about an acre.
Is a commercial mower worth it for a homeowner?
Sometimes. If you have real acreage, keep machines a long time, or mow rough ground, the heavier build pays for itself. If you have a flat half-acre, it is more machine than the job.
What is the difference between the ZT series?
Deck, engine and frame step up together as you move through the line. The comparison page puts them side by side.
