Buying a Kubota GL21 – GL23 – GL27: buying advice & experiences
Suitable for the entire Kubota GL series (Grandel): GL19, GL21, GL23, GL25, GL25K, GL26, GL27, GL29, GL32 and GL33, including the DJ versions GL23DJ and GL27DJ. This series is also known as the Hinomoto NX series (NX19 through NX33).
The Kubota GL21 and its siblings in the GL series (Grandel) are among the most popular compact tractors imported from Japan to Europe. A 4WD tractor of around 1,000 kg with 19 to 33 hp, power steering, and a 16/16 shuttle transmission: that's a package that still performs excellently even thirty years after production. In this buying guide, you'll learn what to look out for, what the differences within the series are, and how the GL series compares to the later GL201 series.
Kubota GL series: the models at a glance
The GL series (Grandel) was built in Japan in the early 1990s and never officially entered the European market – virtually every example here is a grey import. The series shares one basic design: a water-cooled 3-cylinder Kubota diesel engine, four-wheel drive, wet disc brakes, integral power steering, and a shuttle transmission with 16 forward and 16 reverse gears.
| Model | Engine | Power | Weight |
|---|---|---|---|
| GL19 | D1403-L (1,393 cc) | 19 hp / 2,500 rpm | 1,020 kg |
| GL21 | D1403 (1,393 cc) | 21 hp / 2,600 rpm | 1,040 kg |
| GL23 | D1463-L (1,463 cc) | 23 hp / 2,500 rpm | 1,060 kg |
| GL25 / GL25K | D1463 (1,463 cc) | 25 hp / 2,600 rpm | 1,130 / 1,050 kg |
| GL26 | D1503-L (1,499 cc) | 26 hp / 2,600 rpm | 1,200 kg |
| GL27 | D1503-L (1,499 cc) | 27 hp / 2,600 rpm | 1,150 kg |
| GL29 | D1503 (1,499 cc) | 29 hp / 2,700 rpm | 1,190 kg |
| GL32 | D1503-H (1,499 cc) | 32 hp / 2,800 rpm | 1,210 kg |
| GL33 | D1703 (1,647 cc) | 33 hp / 2,700 rpm | 1,290 kg |
When checking the type designation, also pay attention to the letter codes from the manual: S = power steering, M = Monroematic (automatic depth control), MA = Monroematic Auto, U = U-shift transmission, X = reversible PTO, and Y = safety frame. The GL26 and GL33 were supplied with a safety frame as standard.
Kubota GL21 vs. GL201: what's the difference?
The names look similar, but they represent two different generations. The GL19 through GL33 form the first Grandel generation (early 1990s). This was followed by the GL200 series and, from around 1996, the GL201 through GL467 (Grandel II), which was also sold as the Hinomoto NX series. Technically they're closely related: the GL21 and the GL201 both have a 1.4-litre 3-cylinder engine of about 21 hp, the same PTO speeds, and the same layout with 4WD and shuttle. The GL201 series has more modern styling, a redesigned dashboard, and some components differ. Many wear parts such as filters, oil seals, and lighting overlap between the two series, but always check this per part. A full comparison can be found in our article on the specifications of the Kubota GL201 series.
Buying a Kubota GL21: what to look out for
The engines in this series are known to be virtually indestructible, provided maintenance has been kept up. So focus mainly on the maintenance history and not just the hour meter – with grey imports, that's often not original or accurate.
During inspection, be sure to check the following. Start the engine cold: it should start briskly after a short preheat and should not emit blue smoke once warmed up. Check the oil and coolant for emulsion or contamination. Test the shuttle and all gears, the PTO, and the lifting mechanism (raising, lowering, and holding position under load). Look underneath the tractor for leaks at the front axle, rear axle, and steering housing. Check whether the four-wheel drive engages and disengages properly and whether the wet brakes grip evenly on both sides. Rust is rarely an issue with this series; neglected minor maintenance is far more common.
Important with grey imports: note the chassis and engine number from the type plate and always order parts based on that. There are version differences within the series – for example, the GL19 and GL21 have a heavier front axle version than you'd expect based on the build year, which matters for things like oil seals.
What does a Kubota GL series tractor cost?
Prices for these models generally range between €3,500 and €7,500, depending on hours, condition, and specification (indicative, second-hand market as of mid-2026). A GL21 with good tyres, demonstrable maintenance, and a well-functioning lift usually falls in the middle of that range. Examples with Monroematic or a safety frame fetch slightly more.
Is the Kubota GL21 a good choice?
For anyone looking for a compact, reliable 4WD tractor for a paddock, vegetable garden, small-scale contracting work, or forestry work, the GL series is one of the safest choices in this segment. Parts availability is good: filters, gaskets, oil seals, clutch components, and lighting are all readily available. There are weak points too: the tight entry for tall drivers, the lack of a cab, and, on older examples, dried-out fuel hoses and hardened injector nozzles. All of these are fixable and no reason to pass on an otherwise sound tractor.
