On paper, the Ferris ISX800 and Wright ZTS look very similar.
Both are commercial zero-turn mowers designed for serious work. Both run the same Hydro-Gear ZT-3400 drives. Both top out around 10 mph. Both target contractors who want a durable mower without jumping into the $15K+ price range.
But once you move past the spec sheet, these two machines follow very different design philosophies.
One prioritizes comfort and operator experience.
The other focuses on simplicity and durability.
If you’re trying to choose between them, understanding those differences matters more than the specs.

Ferris ISX800: The Comfort-Focused Commercial Mower
The Ferris ISX800 has been on the market since 2018, which gives it something the Wright doesn’t yet have: years of real-world ownership data.
Ferris built its reputation on suspension, and the ISX800 continues that tradition with:
- Independent front suspension
- Rear suspension system
- Suspension seat
Together, these components create one of the smoothest riding zero-turn mowers in this class.
On rough ground, the suspension allows operators to maintain speed without beating up their back or the machine.
Many operators who switch to Ferris say they won’t go back to a rigid mower.
Potential Downsides
That comfort does come with trade-offs.
Compared to simpler machines, the ISX800 has:
- More grease points
- More moving parts
- Higher repair complexity
Some owners also report:
- Deck buildup in heavy or damp grass
- Reduced traction in ditches where suspension unloads a rear tire
None of these are deal breakers, but they are worth knowing before buying.
Ferris ISX800 Key Specs
- Cut Width: 52” or 60”
- Engines: Kawasaki FT730 or Briggs CXi EFI
- Hydros: Hydro-Gear ZT-3400
- Fuel Capacity: 6 gallons
- Top Speed: 10 mph
- Deck: 10-gauge ICD Cutting Deck
- Spindles: Aluminum greasable
- Warranty: 2-year unlimited hours or 4-year / 500 hours
- Price Range: ~$11,700 – $13,100
Wright ZTS: Simplicity and Value
The Wright ZTS is a much newer mower.
That means there isn’t the same long-term ownership data yet, but Wright has a strong reputation for building extremely durable commercial equipment.
Instead of full suspension, the ZTS uses:
- Independent front suspension
- Suspension seat
Interestingly, this suspension style is very similar to what Ferris previously used on models like the IS2100 and IS3200, so while it’s new for Wright, the design itself isn’t unproven.
Where the ZTS really stands out is simplicity.
Wright intentionally designed the mower with fewer service points and less complexity.
Key Design Philosophy
The ZTS eliminates several things common on other mowers:
- No grease points
- Simplified electrical system
- Heavy deck construction
- Sealed cast-iron spindles
The goal is simple: build a mower that is hard to break and easy to maintain.
Wright ZTS Key Specs
- Cut Width: 52” or 61”
- Engine: Kawasaki FT730
- Hydros: Hydro-Gear ZT-3400
- Fuel Capacity: 7.5 gallons
- Top Speed: 10 mph
- Deck: 7-gauge AeroCore deck
- Spindles: Ductile iron sealed
- Warranty: 2-year unlimited hours or 5-year / 500 hours
- Price Range: ~$11,400 – $11,600
Ferris ISX800 vs Wright ZTS: Key Differences
When you compare these machines side-by-side, a few clear differences appear.
Ride Comfort
Winner: Ferris
Ferris still leads the industry in suspension design. If you mow rough ground daily, the ride quality difference is noticeable.
Simplicity & Maintenance
Winner: Wright
Fewer moving parts and no grease points mean less maintenance over time.
Deck Strength
Winner: Wright (on paper)
A 7-gauge deck with iron spindles is heavier-duty than the Ferris 10-gauge deck with aluminum spindles.
Engine Options
Winner: Ferris
Ferris offers more engine choices, including EFI and higher horsepower options.
Drivetrain
Winner: Tie
Both mowers use the same Hydro-Gear ZT-3400 transmissions, which are proven in this class.
Final Verdict
If price were equal, the Ferris ISX800 would likely be the safer choice.
It offers:
- Full suspension
- Years of real-world data
- Excellent ride comfort
However, price is rarely equal.
If the Wright ZTS is $700–$2,000 cheaper, the equation changes.
At that point the ZTS becomes a compelling option because you get:
- Lower upfront cost
- Simpler maintenance
- Heavy-duty deck construction
- Proven Wright durability
In other words:
- Choose Ferris if comfort is your priority.
- Choose Wright if simplicity and value matter most.
Both are legitimate commercial machines.
There isn’t a wrong choice here.
