Cub Cadet’s New Ultima Mowers

Cub Cadet’s New Ultima MowersCub Cadet’s new Ultima ZTR isn’t just an update, it’s an all-new model that uses new construction techniques. The result is a level of performance and comfort that would make it competitive in the commercial market, yet it’s sized and priced to be within reach of consumers.


The first thing most people notice when seeing the new Ultima is its unusual frame. Instead of using a flat ladder frame, it uses a continuous, fully welded 2×2 inch tubular square spaceframe that wraps around major components, adding stability and stiffness while keeping weight down.

The operator sits in a high back seat attached using polymer isolation mounts, while the foot plate has a rubber mat and the lap bars have overmolded hand grips. Together, these parts limit the transfer of vibration to the operator, making the Ultima exceptionally comfortable. Getting a good hand position is easy: just loosen the knob near the base of the lap bar, hold the bar where it feels comfortable, and tighten the knob back down. No tools are required.

Need to mow when the sun isn’t cooperating? LED work lights are built into the foot plate so you can mow when it’s cloudy or dark out.


The Ultima is offered with decks ranging from 42 to 60 inches. Deck height is set using a spring assist foot lever coupled to a large, clearly-marked knob next to the operator. Just push down on the lever and twist the knob to one of 15 settings ranging from 1 to 4.5 inches.

All but one model comes with Cub Cadet’s new Aeroforce deck. It uses a constructed shell with internal baffles and blades designed to deliver performance approaching that of a stamped deck. In independent tests conducted by Ohio State University, the Aeroforce outperformed every competing deck in the market segment, delivering a better finish with less clumping.

All models have an offset front axle that lets you get closer to curbs and edges, reducing the amount of trimming you’ll need to do after you mow.


The frame is built so that it surrounds the engine, protecting it from impacts without blocking large sections like the steel panels used on most ZTRs. The spindles are maintenance free, and the footplate can be pulled out to get access to the belts without having to remove the deck. The battery can be accessed by flipping up the seat.


The Ultima is available with Kohler’s 7000 Series and Kawasaki’s FR Series. Both models are consumer engines, but they’re based on their professional counterparts. Full pressure lubrication systems and heavy-duty air cleaners help ensure a long life.


ZT1 42
This model has a 22 HP Kohler 7000 Series engine and uses a pair of Hydro-Gear EZT-2200 wheel motors that can propel the mower to a top speed of 7 mph going forward and 3 mph in reverse. Its 42-inch deck is the only one in the lineup that uses a stamped shell, trading durability for a better finish.

ZT1 46
This model has the same engine and hydrostatic system as the 42, but it comes equipped with a 46-inch Aeroforce deck.

ZT1 54
Step up to this model and you’ll get a Kohler 7000 rated at 24 HP and a 54-inch Aeroforce deck.

ZT1 50
This model uses a 23 HP Kawasaki FR Series and comes with a 50-inch Aeroforce deck.

ZT2 50 and 54
ZT2 models use ZT-2800 hydrostatic motors, increasing top speed to 7.5 mph going forward and 3.5 mph in reverse. The ZT2 50 has a 50-inch Aeroforce deck, while the 54 has a 54-inch deck. Both models are powered by a 23 HP Kawasaki FR Series.

ZT2 60
The top-of-the-line Ultima mower has a 24 HP Kawasaki FR Series and a massive 60-inch Aeroforce deck.


Cub Cadet offers a limited lifetime on frame and fabricated deck shell. Kohler and Kawasaki guarantee their engines for three years with no hour limit, and Cub Cadet offers the same guarantee for everything on the mower aside from the deck and engine.
