Kubota Z421 Zero Turn Mower Review (2024)

The Kubota Z421 Zero Turn is a well-built semi-commercial mower. It is great for a part-time lawn care owner or homeowner with a large yard. This durable mower is easy to control and is capable of mowing a lot of grass, as you will see in this Kubota Z421 review.

While demoing this mower, I was surprised by the power and cut quality. The kawasaki engine, that is popular on many other mowers, offers plenty of power for some of the most demanding lawns. The cut quality of this mower was very good. It did a great job of dispersing clipping quickly and evenly.

The Kubota Z421 isn't the most comfortable mower on the market, but if you're looking for a simple mower that will last a long time and not break the bank, this is the mower for you. Let's take a look at some of the details.

Power

The Kubota Z421 provides a Kawasaki engine that produces the torque necessary to go through the toughest lawns. The Z421 features an air-cooled two-cylinder gasoline engine that produces 24 horsepower.

The Z421 provides a slight boost over the 22 horsepower you'd get from the Z411, the other mower in the Kubota Z400 line. The engine also uses a key switch starter.

Features

The Kubota Z421 uses the Hydro-Gear Commercial ZT3600 transmission to move power from the Kawasaki engine to the wheels. The transmission helps the Z421 move at about 10 miles per hour.

You can control the speed with a two-hand lever, while the foot pedal helps you stop the mower.

You can push and release the locking pedal on the deck to raise it up and then use the dial to adjust the cutting height. Push and release the pedal once more to lower the deck again to cut at the height you prefer. The dial system lets you adjust the cutting height by quarter-inch increments.

The rear tire is 24 inches and features a low profile, while the front tire is 13 inches and features a smooth surface with a pneumatic control setup. The extensive footprint on the tires prevents ground compaction while also preventing turf damage when turning.

You've also got a massive fuel tank that can fit about 6.8 gallons. You could keep your mower going for about six hours before refueling, although that number depends on conditions. The tank also features a sight window to display how much fuel is left.

Cut Quality

You can order the Kubota Z421 with a 54 or 60-inch deck.

The Z421 features three blades that slice through each bit of grass in moments. The blades are angled to produce a clean cut that prevents stress on the grass. The blades also raise the grass to ensure they are trimmed right, even if the grass is long or slightly damp.

You can also adjust the cutting height from 1.5 to 5 inches with increments of 0.25 inches in between. The dial system allows you to adjust the cut height.

Durability

Kubota has put in enough effort in ensuring the Z421 stays active and functional through any cutting project. The mower features a five-inch-deep welded deck with a sturdy steel body. All steel parts are reinforced and bolted to provide a secure layout that won't buckle.

Comfort

The large low-profile rear tire on the Kubota Z421 mower provides enhanced traction while absorbing shocks on the ground. The zero-turn mechanism on the wheels also ensures the mower can move over grass without creating excess vibrations while turning.

The seat is soft and features a high back. The seat slides six inches forward and back for your comfort. It has armrests to keep you relaxed while mowing. The foot pan is also wide enough to handle an easy entry and exit from the mower. The controls are also ergonomically laid out on the right side for easy access.

Aesthetics

The low profile on the Kubota Z421 makes it look appealing. The rollover protection structure at the top adds a quality look while also preventing significant rollover concerns. The structure also folds down for when you need to go under a low-clearance space or you need to store the mower in a compact area.

Build Quality

The welded steel deck is one of the best parts of this mower, as it provides a sturdy body that stays functional. The cover over the engine has enough vents to allow hot air to move out and prevent overheating, but the design keeps the physical body secure to where outside items won't enter the engine.

Safety

The rollover protection system bar meets all ISO 21299 specifications to keep potential rollover situations under control. The foot pedal parking brake will keep the mower secure so it will not move until you are ready to start mowing. The key-based start and stop feature also prevent people from accidentally starting the mower.

Price

The last part of this Kubota Z421 review to note involves the price of the mower. The 54-inch model is available for $7,227, while the 60-inch version is $7,770. Kubota provides various features to help people pay for their mowers, including a 0% down payment and no APR for 48 months. The offers Kubota provides for its mowers will vary.
