The Kubota B6000 tractor is equipped with a 35.2 cu.in (577 cc) Kubota ZL600 vertical two-cylinder naturally aspirated water-cooled diesel engine with a rated power of 12.5 hp (9.3 kW) and 32.9 Nm (24.4 lb-ft) of maximum torque at 2000 rpm.

The manual shift transmission consists of a dry single plate clutch and unsynchronized gearbox with 6 forward and 2 reverse gears. Max. travel speed (forward and reverse): 7.7 mph (12.5 kph) / 4.2 mph (6.7 kph). The open center hydraulic system includes a gear pump with a rated capacity of 2.8 gpm (10.8 lpm).

The main relief pressure is 83 bar (1200 psi). The 2WD models are equipped with 4.00x9 front tires and 7.00x16 rear tires. The 6.00x12 or 20x8.00-10 front tires and 7.00x16 or 27x8.50-15 rear tires are used for 4WD tractors.
