Comparison Between Kubota Z421 Vs Z422

Features Of Kubota Z421


The Kubota Z421 mower has a big low-profile rear wheel that enhances traction and absorbs ground vibrations. Using zero-turn wheels also ensures that the mower doesn’t create excessive vibrations while turning over grass.

The back of the seat is particularly high, and the cushioning is plush. For your convenience, the seat can be moved forward and back by six inches. To keep you comfortable while mowing, it has armrests.

In addition, the mower’s foot pan is wide enough to allow for a simple entry and exit. In addition to being conveniently located on the right side, all of the controls are also designed with user comfort in mind.


To ensure that the Z421 remains operational during any cutting project, Kubota has invested a significant amount of time and effort. With a 5-inch-deep welded deck and a strong steel chassis, this mower is built to last longer. Steel pieces are strengthened and fastened together for a sturdy structure that won’t sag or collapse over time.

Quality Of The Cut

The Kubota Z421 can be ordered with either a 54-inch or 60-inch deck. Three razor-sharp blades on the Z421 make quick work of even the thickest grass. To avoid stressing the grass, the blades are inclined.

Even if the grass is long or slightly damp, the blades elevate the grass to ensure that it is trimmed correctly. The cutting height can also be adjusted from 1.5 to 5 inches with 0.25-inch increments in between. The height of the cut can be adjusted using the dial mechanism.


Powered by a Kawasaki engine, the Z421 employs a Hydro-Gear Commercial ZT3600 gearbox to provide power to the wheels. The Z421 can reach a top speed of 10 miles per hour because of its transmission. The mower’s speed and stopping power are controlled by a two-handed lever and a foot pedal, respectively.

The cutting height can be adjusted by pushing and releasing the locking pedal on the deck. Once again, push and release the pedal to lower the deck to the desired cutting height. Cutting height can be adjusted in quarter-inch increments using the dial mechanism.

It has a low-profile rear tire measuring 24 inches and a smooth surface measuring 13 inches with a mechanical control arrangement. Ground compaction is prevented by the tires’ large footprint, which also reduces turf damage when turning.

Additionally, you’ve got a 6.8-gallon gasoline tank. Depending on the weather and other factors, you may be able to use your mower for up to six hours before needing to refill. Sight windows show how much fuel is remaining in the tank.


With its Kawasaki engine, the Kubota Z421 can tackle even the most difficult lawns. The Z421 is powered by a 24-horsepower two-cylinder gasoline engine with air cooling. Z421’s 22 horsepower is slightly higher than Z411, the other Kubota Z400 mower in the lineup. A key switch starter is also used to start the engine.


The Kubota Z421’s modest profile makes it attractive. At the top, the rollover safety structure provides a high-quality appearance while also preventing serious rollover issues. If you need to fit the mower into a tight place, the structure may be folded down so that it can fit beneath a low-clearance region.

Build Quality

One of the main features of this mower is the welded steel deck, which gives a robust body that is always functioning. To preserve the engine from overheating, the engine cover contains several vents that allow hot air to escape while also keeping the physical body secure.


In the event of a rollover, the accident protection system bar complies with all ISO 21299 criteria. Mowers can be parked with a foot pedal parking brake to prohibit them from moving while they are being used.
