KUBOTA Z1-421 Petrol Zero-Turn Mower (Z1-421)

Kubota Z1-421 Petrol Zero-Turn Mower – A Premium Machine with Outstanding Manoeuvrability

Designed for faster, smarter lawncare, the Kubota Z1-421 Petrol Zero-Turn Mower delivers professional-looking results for homeowners with larger lawns. Combining a powerful Kawasaki V-twin engine, responsive zero-turn steering and durable 107 cm cutting deck, this premium machine makes light work of large, landscaped gardens.

The Kubota Z 421 zero turn mower offers superb cutting quality, impressive comfort features and straightforward operation. Its compact dimensions allow it to work efficiently around trees, flower beds and garden features, while Kubota’s expert engineering ensures it’ll remain unbeatably reliable for years.

Reliable Kawasaki V-Twin Power

This ride-on mower is fitted with a Kawasaki 726 cc air-cooled petrol engine producing 14.1 kW (19 hp). It’s a smooth-running 90-degree V-twin engine that has been developed to provide dependable performance, low vibration and excellent fuel efficiency throughout demanding mowing sessions.

A robust cast aluminium crankcase and cylinder heads help to keep overall weight down while maintaining excellent durability. The generous 12.2-litre fuel tank allows longer periods between refuelling stops, making this zero turn mower ideal for extensive residential properties.

Routine maintenance has also been made simple. The combined filler and dipstick are positioned for convenient access, while key service points are easy to reach during regular inspections.

Zero-Turn Steering for Outstanding Control

One of the biggest advantages of the Kubota Z 421 is its exceptional manoeuvrability. Kubota’s zero-turn steering system allows the mower to rotate within its own footprint, making it easy to navigate around obstacles with remarkable precision.

Twin steering levers independently control each rear drive wheel, giving smooth and accurate forward and reverse movement. Tight turns around trees, borders and shrubs become far quicker than with a conventional lawn tractor.

The motion lever drive system works alongside Hydro Gear EZT® (ZT-2200) hydrostatic transmission, providing infinitely variable speed control without gear changes. This allows the mower to accelerate smoothly up to 10.5 km/h (6.5 mph) when travelling forwards and up to 6.4 km/h (4 mph) in reverse.

Low-profile drive wheels and an electromagnetic PTO clutch both contribute to dependable everyday performance and effortless operation.

Professional Cutting Quality Every Time

The Kubota Z421 zero turn includes a strong welded rotary deck measuring 107 cm (42 inches) wide. A substantial 114 mm deck depth helps deliver consistent airflow, improving grass lift for a cleaner, more even finish.

Once the twin blades have cut the grass, it is efficiently discharged to the side of the machine. The blades’ improved design reduces operating noise without compromising cutting performance. The result is a crisp, professional-quality finish across a wide range of grass conditions.

Cutting height can be adjusted between 38 mm and 108 mm (1.5 to 4.25 inches). A simple rotary dial allows precise adjustment in 6 mm increments, making it easy to achieve the exact finish you require throughout the growing season.

Deck lifting is equally convenient thanks to the foot-operated mechanical lift system, leaving you with both hands free to control the machine.

Optional Mulching for an Even Healthier Lawn

For customers interested in mulching, we sell the Kubota Z421 Mulching Kit as an optional extra.

Once this is fitted, rather than collecting or ejecting grass clippings, the mower finely chops them before returning them to the lawn. This helps recycle valuable nutrients, supports healthy grass growth and reduces the need for waste disposal.

As you can see, Kubota zero turn mowers Z421 are flexible machines, able to adapt to different mowing preferences throughout the year.

Comfort Designed into Every Detail

Long mowing sessions become far more enjoyable thanks to Kubota’s thoughtful operator-focused design. The spacious platform provides generous legroom, making it easy to climb on and off the machine while allowing comfortable movement when driving.

Kubota’s K-Ride comfort system features a deluxe high-back seat complete with adjustable suspension, lumbar support and armrests. The seat is easy to slide backwards and forwards, allowing operators of different heights to find a comfortable driving position.

The steering levers are also adjustable to suit the operator, helping maintain precise control. A conveniently positioned cup holder keeps refreshments close at hand—ideal for long mowing sessions in warmer weather.

Simple Controls and Easy Maintenance

Every one of the Kubota zero turn Z421’s controls has been positioned for intuitive operation. The steering levers, deck lift, height adjustment dial and switches are all within easy reach, allowing new users to become familiar with the machine quickly.

A practical wash port allows the deck to be cleaned by simply attaching a garden hose, helping remove wet grass and debris after use. Removing the floor panel provides fast access to the drive belts, simplifying routine inspection and maintenance.

Built for Safety and Durability

Like all Kubota machines, the Z1-421 has been engineered for years of dependable service. It has a very sturdy construction and weighs 282 kg, helping provide excellent stability while mowing.

A high, rigid roll bar comes fitted as standard, offering the driver additional reassurance during operation.

This riding mower measures 1,890 mm (L) x 1,075 mm (W – without the discharge deflector) x 1,650 mm (H), giving it a compact footprint without sacrificing operator comfort or mowing capability.
