About the Kubota B5100

The first Kubota B5100 Tractors went out of the factory gates in 1978 and they kept building them until 1984. Sometimes, the parts compatibility is determined by the serial number of your Kubota B5100 Tractor, and that info should be listed on the part fit notes. Some Kubota B5100 Tractors have a 4x2 2WD chassis, but there are also some with a 4x4 MFWD 4WD chassis, all equipped with manual steering. They also have differential mechanical shoe brakes. The type I 3-point hitch is very reliable, capable to lift 300 lbs [136 kg]. It is also worth noting that the transmission rear PTO runs at 540/1000 rpms.
