Features Of Kubota B6100 Tractor

Kubota B 6100 is a sub-compact utility tractor developed by the Kubota company in Japan. This is a good quality 2WD or 4WD tractor with great features. Here are the key features of the Kubota B 6100 model tractor.


Kubota B6100 has a 3 cylinder Kubota Diesel Engine producing 14 horsepower. The utility tractor uses the D650-A engine. It is a 0.7 L, 675 cm2, (41.2 cu·in) liquid-cooled, natural aspirated engine. Its cylinder bore is 64.0 mm (2.52 in) and the piston stroke is 70.0 mm (2.76 in). This engine produces 14 PS (10.3 kW; 13.8 HP) at 2,800 RPM of gross horsepower.


Kubota B6100 uses a choice of 2 transmission boxes to get the Power from the engine to the wheels. The first is a hydrostatic transmission that gives the tractor infinite speeds both in forward and reverses. This means there is no need for a gear stick to change speed. This system is particularly helpful for using the vehicle in tough and confined spots. It is effective when you constantly need to change speeds from forward to reverse.

The other choice is an unsynchronized transmission system. This provides the tractor 6 gears when traveling forward and 2 gears when it reverses. This transmission system has an oil capacity of 11.5 liters. The maximum speed of the Kubota B6100 is 13.8 kph (8.6 mph).

Manufacturing Year

The Kubota Tractor Company provides a unique vehicle identification number (VIN) to all of its models. This tells you the year and the month of production. You can find the VIN by following the below simple process.

Step 1

Lift the hood of the tractor to find the VIN. The VIN might be located on top of the valve, printed either by the oil filter or on the rear of the engine. It is a six-digit series containing letters and numbers.

Step 2

The first character in the VIN, either a number or a letter, identifies the year of production. The second character, a letter, indicates the month of production.

Step 3

If the VIN begins with a number, add 2000 to the number to determine the year of production. For example, if the VIN begins with 4J, the tractor was made in 2004. If it’s 5J, it was made in 2005, and so on.
