Kubota B2-231 DB: compact four-wheel-drive tractor with 16 kW, a water-cooled three-cylinder diesel and an enclosed cab for confined working spaces
Kubota is a Japanese manufacturer that has made its international name chiefly with compact four-wheel-drive tractors for garden, municipal and smallholding use. The B2-231 DB belongs to the smallest power class of this range.

The B2-231 DB is powered by a water-cooled three-cylinder diesel engine of 1,123 cm³ displacement, delivering 16 kW, or 21 hp, at 2,500 rpm. Cab height is 1,597 mm, width is 1,092 mm and the wheelbase is 1,500 mm. The front hydraulics lift up to 970 kg, and drive is delivered to all four wheels.
At under 1.1 m wide with four-wheel drive, the B2-231 DB belongs to the compact tractors designed for narrow lanes in nurseries, cemeteries or municipal service. The enclosed cab allows year-round use in all weather, while the small overall size makes turning in confined spaces possible, and the wide track for such a narrow machine helps keep it stable when working close to kerbs and raised beds.
When buying a used compact tractor of this type, it is worth checking the front hydraulics for leaks at the lift cylinder and valves, since implements are frequently swapped here. The cab should be checked for rust at the sealing surfaces, and the engagement of the four-wheel drive for smooth operation. The steering linkage and front axle pivot also deserve attention, since compact tractors of this size are often steered sharply in tight spaces. Kubota spare parts for this size class are generally well available through specialist dealers.
