More about the John Deere 6603

John Deere started producing the 6603 Tractor in 2002 and continued until 2008. Be sure to look for any serial number comments in the part fit notes. In some cases, the John Deere 6603 Tractor parts you need depend on your serial number. Some John Deere 6603 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 mechanical wet disc brakes. The type II 3-point hitch is very reliable, capable to lift 5,292 lbs [2400 kg]. It is also worth noting that the independent rear PTO runs at 540, 1000 rpms.
