For many, the jump from a traditional lawn tractor to a zero-turn mower is intimidating. The learning curve of "lap bars" can be steep, and the stability on slopes can feel uncertain. At WGM Ltd, we are seeing a massive shift in interest toward the Cub Cadet Ultima ZTS Series.
The "S" stands for Steering, and it represents a revolution in lawn care. By combining the 360-degree maneuverability of a zero-turn with a familiar steering wheel, Cub Cadet has created a machine that is both incredibly fast and exceptionally stable on hills.
In this article, we look at the three core tiers of the range: the Z1 107, the Z2 117, and the flagship Z3 127.

Synchro-Steer™: The Secret to Hill Stability

The standout feature across the Z1, Z2, and Z3 is Synchro-Steer™ technology.
Unlike traditional zero-turns where the front caster wheels "flick" around freely, Synchro-Steer links the steering wheel to both the front wheels and the independent rear transmissions. When you turn the wheel, the front wheels steer while the rear wheels vary their speed simultaneously.

The Benefits:

• Unmatched Stability: Handles slopes of up to 20 degrees where lap-bar models might slide.
• No Turf Tearing: Because the front wheels are steered, they don't dig into the grass during tight turns.
• Familiarity: If you can drive a car, you can operate a ZTS.

Z1 107S: The Entry-Level Powerhouse

The Z1 107S is the perfect introduction to zero-turn mowing. It features a 107cm (42") AeroForce™ fabricated deck, which is welded rather than stamped for superior durability. It’s ideal for large residential lawns where you need to navigate around trees and flower beds with precision.

Z2 117S: The Professional Choice

Stepping up to the Z2 117S brings the legendary Kawasaki V-Twin engine into the mix. Kawasaki engines are renowned for their longevity and smooth power delivery. You also get a larger 117cm (46") cut and upgraded EZT 2800 transmissions, which are more robust for tackling slightly rougher terrain.

Z3 127S: The Estate Master

The Z3 127S is designed for those with significant acreage. With a massive 127cm (50") triple-blade deck, it slashes mowing time. It features the ZT 3100 commercial-grade transmissions, which are serviceable (unlike the Z1 and Z2), meaning this machine is built to last for decades with the right maintenance.

Comfort & Maintenance

Cub Cadet hasn't just focused on the "business end" of the mower. The Ultima series is built around the driver:

• Open Frame Design: Makes it incredibly easy to get on and off the machine, with plenty of legroom.
• LED Headlights: Standard across the range, allowing you to finish the job as the sun goes down.
• Easy Deck Access: The floor pan can be removed without tools, allowing you to clean the top of the deck and access the belt drive in seconds.

Which one is right for you?

If you have a standard large garden and want to move away from a tractor, the Z1 107S is a fantastic value. However, if your land is hilly or you want the extra peace of mind of a Kawasaki engine, we highly recommend the Z2 117S. For estate owners who want a machine that bridges the gap between residential and commercial performance, the Z3 127S is the ultimate choice.
