The Kubota B2650 tractor, with its rich heritage, reliable engine, advanced transmission, and versatile features, is a valuable asset to the agricultural sector. Kubota’s commitment to excellence shines through in this compact utility tractor, Let’s learn more about prominent features:


The Kubota B2650 compact utility tractor is equipped with the highly reliable Kubota D1305 engine, which is renowned for its exceptional performance and efficiency. This three-cylinder, natural aspirated diesel engine boasts a displacement of 1.3 liters and a total capacity of 1261 cm² (76.9 in). It features a cylinder bore of 78.0 mm (3.07 in) and a piston stroke of 88.0 mm (3.46 in). These specifications contribute to the engine’s outstanding power delivery and fuel economy, making it an ideal choice for agricultural applications.

The Kubota D1305 engine generates an impressive maximum output power of 26.4 PS (19.4 kW; 26.0 HP) at 2,500 rpm. This power ensures that the Kubota B2650 tractor can handle a wide range of demanding tasks with ease. Whether it’s plowing through tough soil, mowing dense vegetation, or hauling heavy loads.


The Kubota B2650 tractor is equipped with a hydrostatic transmission, which is a modern and efficient transmission system. This type of transmission uses hydraulic fluid to transfer power from the engine to the wheels, providing smooth and seamless speed control. The B2650’s hydrostatic transmission features infinite (3-range) forward and reverse gears, allowing the operator to select the appropriate speed for the task at hand.

This versatility enables precise control and maneuverability in various operating conditions. Whether it’s slow and precise movements for delicate tasks or higher speeds for efficient transport, the hydrostatic transmission provides the flexibility to match the tractor’s speed to the specific requirements of the job.

With the hydrostatic transmission, the Kubota B2650 offers impressive speed capabilities. It can achieve a maximum forward speed of 19.0 km/h (11.8 mph) and a maximum reverse speed of 14.3 km/h (8.9 mph). This allows the tractor to cover more ground quickly and efficiently, reducing the time required to complete tasks and improving overall productivity. The transmission oil capacity of the Kubota B2650’s hydrostatic transmission is 15.0 liters (15.85 US qt, 13.2 Imp qt).

Hydraulic System

The Kubota B2650 tractor is equipped with an open-center hydraulic system, a reliable and versatile hydraulic type commonly used in agricultural machinery.

The Kubota B2650 has a hydraulic capacity of 15.0 liters (15.85 US quarts, 13.2 Imperial quarts). This capacity ensures an ample supply of hydraulic fluid to meet the demands of the hydraulic system, The tractor features a single hydraulic valve, which acts as a control mechanism for regulating the flow of hydraulic fluid to specific attachments or implements.

The pump flow of the hydraulic system on the Kubota B2650 is 5.0 gallons per minute (18.9 liters per minute), the 5.0 gpm pump flow ensures a steady and reliable supply of hydraulic power.

The total flow of the hydraulic system is 8.7 gallons per minute (32.9 liters per minute). This total flow rate combines the pump flow with other hydraulic functions, providing sufficient power for simultaneous operation of multiple hydraulic systems or implements. For steering functionality, the Kubota B2650 has a dedicated steering flow of 3.7 gallons per minute (14 liters per minute).

Other General Features

The Kubota B2650 comes packed with a host of features designed to optimize efficiency and operator comfort. With power steering, maneuvering the tractor becomes effortless, allowing operators to navigate their fields with precision. The inclusion of wet disc type brakes ensures reliable and responsive stopping power, enhancing safety during operation.

The B2650 offers two operator station options. The B2650HSD version provides an open operator station with a two-post ROPS (Roll-Over Protective Structure), ensuring operator safety in case of accidental rollovers. On the other hand, the B2650HSDC version comes with a fully enclosed cab equipped with air-conditioning, providing a comfortable working environment in all weather conditions.

Additionally, the Kubota B2650 features a sizable 27.5-liter (7.3 US gal.; 6 Imp. gal) fuel tank, enabling long hours of uninterrupted operation.
