About the KUBOTA GR2120 Diesel Ride-on Mower
Kubota GR2120 Diesel Ride-On Mower: A Feature-Packed Machine for Demanding Private Users
Expertly engineered for premium performance and exceptional operator comfort, the Kubota GR2120 Diesel Ride-On Mower meets the highest standards for both cutting quality and reliability. Designed for people who take pride in their lawns, this superb tractor mower combines Kubota’s renowned diesel efficiency with outstanding manoeuvrability and robust build quality. From its advanced steering system to high-capacity collection unit, every feature has been crafted to make mowing faster, cleaner, and much more enjoyable.
Reliable Diesel Power You Can Trust
At the heart of the GR2120 ride on mower lies a robust three-cylinder, water-cooled 778 cm³ diesel engine delivering 15.7 kW (21 hp) of consistent power. Kubota’s reputation for durability shines through in this design, which provides exceptional reliability and noticeably lower fuel consumption than petrol models. The engine’s smooth performance ensures dependable operation even under heavy loads, while an 18-litre fuel tank allows you to work uninterrupted for longer periods of time. Forward travel reaches 10 km/h (6 mph), with 5 km/h (3 mph) in reverse, giving you confident control across large areas of lawn.
Advanced Glide Steer Technology for Maximum Agility
Kubota’s Glide Steer technology transforms the way you handle tight spaces. This innovative hydraulic power steering system allows the front wheels to turn at an impressive 70° angle, letting you mow closely around trees, borders, and garden obstacles with remarkable precision. The result is an exceptionally small turning circle and minimal uncut grass left behind. It also helps preserve your lawn’s condition by preventing turf damage during tight manoeuvres. Combined with its four-wheel drive, the GR2120 moves smoothly across slopes, uneven ground, and narrow spaces with equal confidence.
Hydrostatic Transmission for Easy Handling
Efficient operation is a hallmark of the GR2120 ride on mower’s design. The hydrostatic transmission is controlled by a single pedal, allowing you to switch between forward and reverse seamlessly. This responsive system delivers consistent speed control and effortless handling. Kubota’s cardan shaft drive also supports smooth power transfer, while the oil-cooled PTO clutch enhances durability and reliability. The shaft-driven deck eliminates the need for belts, offering a more direct and efficient power delivery that demands less maintenance over time.
Superior Cutting and Collection Performance
When it comes to grass cutting results, the Kubota GR2120 excels. Its three-blade cutting deck has a generous 122 cm (48-inch) width, designed to maintain a clean and uniform finish across large areas of lawn. The hydraulically operated deck lift makes height adjustments easy, offering 11 cutting positions ranging from 25 mm to 102 mm. This ride on mower also supports reverse mowing, allowing for greater flexibility when trimming around obstacles.
Collected clippings are handled by a spacious 450-litre grass collector, complete with an electronic sensor that alerts you when it’s time to empty. Two side-mounted levers make the unloading process quick and thorough, while the enlarged discharge chute prevents blockages to keep your mowing session flowing smoothly.
A1 Operator Comfort for Enjoyable Lawnmowing
Kubota places a lot of emphasis on user comfort. The flat operator’s platform provides ample legroom and easy access to controls, while the soft-upholstered seat features parallel-linkage suspension for comprehensive support on uneven ground. Low-effort power steering and a relaxed seating position reduce fatigue during long mowing sessions, ensuring comfort without compromising on cutting precision. Every element of this machine is designed to make extended mowing tasks as pleasant as possible.
Safety and Peace of Mind
Safety is another of Kubota’s top priorities. The GR2120 riding mower is equipped with a seat belt and Rollover Protection Structure (ROPS) to shield the operator in the unlikely event of the machine turning over. This robust, thoughtfully designed feature helps you work confidently in all conditions. It can be folded down when driving under arches or through shed doors, and for convenient garden storage.
Optional Attachments for Greater Versatility
Kubota’s GR2120 is more than a ride on mower—it’s a year-round garden tractor. Optional attachments include a rear deflector, mulching kit, tow hitch, and lawn roller assembly, making this machine adaptable to a range of garden and estate maintenance tasks. The roller is ideal for creating a traditional striped finish, while the mulching kit recycles clippings into a nutrient-rich feed for your lawn.
Top Company, Solid Warranty
Over five decades in the business, Kubota is established as one of the world’s most trusted names in ground care. The GR2120 epitomises the company’s engineering expertise. For your added peace of mind, it is backed by an excellent two-year manufacturer’s warranty from the date of purchase (terms and conditions apply).

Roger Mitchell –
I have owned a GR2021 for 5 years . It takes care of my 2.5 Acre parkland/garden , navigating the trees with ease . It has proved very reliable and a joy to use , even cutting long grass .
On the minus side , the diesel engine whilst powerful is noisy, it is not happy collecting wet grass ( what mower is ) and the cost of replacement belts is prodigious !
