About the John Deere 6403

Production of the John Deere 6403 Tractor started in 2002 and continued until 2008. Sometimes, the parts compatibility is determined by the serial number of your John Deere 6403 Tractor, and that info should be listed on the part fit notes. Some John Deere 6403 Tractors have a 4x2 2WD chassis, but there are also some with a 4x4 MFWD 4WD optional chassis, all equipped with hydrostatic power steering. They also have differential wet disc brakes. The type II 3-point hitch is very reliable, capable to lift 4828 lbs [2189 kg]. It is also worth noting that the independent rear PTO runs at 540, 1000 rpms.
