Features Of Kubota B1550 Tractor

The Kubota B1550 tractor is a powerful and reliable machine that is designed to meet the needs of modern agriculture with its exceptional engine, versatile transmission, and other general features. Lets learn about its prominent features in-depth:

Engine

The Kubota B1550 utility tractor is equipped with a powerful and efficient engine, the Kubota D850-5B. This diesel engine is a natural aspirated three-cylinder design, with a displacement of 0.9 L (855 cm2 or 52.2 cu·in). The engine boasts a cylinder bore of 72.0 mm (2.83 in) and a piston stroke of 70.0 mm (2.76 in), which contributes to its exceptional power and performance.

The Kubota D850-5B engine in the B1550 tractor produces a gross horsepower of 17.3 PS (12.7 kW; 17.0 HP), which is more than sufficient for most agricultural tasks. It also delivers 14.1 PS (10.4 KW; 14.0 HP) of PTO output power, which makes it ideal for powering various implements such as mowers, tillers, and other equipment.

This engine is designed to deliver maximum power with minimal fuel consumption, which makes it an economical choice for farmers and other agricultural workers. It also has a low-emission design, which makes it environmentally friendly and compliant with the latest emission regulations.

Transmission

The Kubota B1550 utility tractor is equipped with a gear shift transmission with a dry single plate type clutch. This type of transmission is commonly found in small and mid-sized tractors, as it is durable, efficient, and straightforward to operate. The gear shift transmission in the B1550 tractor has six forward gears and two reverse gears, which provides operators with a wide range of speed options to suit different applications.

The B1550 tractor’s transmission allows for a maximum speed of 12.6 km/h (7.8 mph) in forward gears and 5.2 km/h (3.2 mph) in reverse gears. This speed range is suitable for most agricultural tasks, such as plowing, tilling, and mowing. The transmission oil capacity of the B1550 tractor is 12.0 L (12.68 US. qt, 10.56 Imp. qt.). Regular maintenance of the transmission is essential to keep the tractor running smoothly and efficiently. This includes checking the transmission oil level regularly, and inspecting the transmission for signs of wear and tear.

Hydraulic System

The Kubota B1550 tractor is equipped with an open-center hydraulic system. The hydraulic system in the B1550 tractor has a capacity of 12.0 L (12.68 US. qt, 10.56 Imp. qt.), which is ample for most agricultural applications. The hydraulic pump has a flow rate of 5.5 gpm (20.8 lpm), which provides enough pressure and flow to operate hydraulic cylinders, motors, and other attachments.

The open-center hydraulic system in the B1550 tractor uses a hydraulic pump to generate pressure, which is then distributed to the hydraulic lines and cylinders. The open-center design allows fluid to flow freely when the valve is in the neutral position, which reduces heat buildup and improves fuel efficiency.

The hydraulic system in the B1550 tractor is essential for operating many attachments, such as loaders, backhoes, and cultivators.

Other General Features

In addition to its engine and transmission, the Kubota B1550 tractor comes with several other features that make it a top choice in the agricultural sector. It features recirculating ball manual type steering or integral type power steering, depending on the model, which provides easy and efficient handling in the field. The internal-expanding type brakes are right and left independent with an interlock device, which offers excellent safety and control during operation.

The open operator station with two-post ROPS provides excellent visibility and comfort for the operator, allowing them to work for long hours without fatigue. The 18.0 liters (4.8 US gal.; 4 Imp. gal) fuel tank capacity ensures that the tractor can operate for extended periods without needing to be refueled.
