More about the John Deere 4320

The John Deere 4320 Tractor was manufactured between 2005 and 2014. Regardless of whether you initially got a deal on your tractor (lower than the initial price of $12,000 (1972)), with TractorJoe you'll get the best deal on the spare parts you need. You can find in our inventory every kind of spare part you might need to keep your John Deere 4320 Tractor running smoothly. Make sure you have access to your tractor serial number, because there is a chance that the John Deere 4320 parts you need depend on that serial number. That serial number is determined by the year of manufacturing, so for a 2005 model, it starts with 230001, for a 2006 model it starts with 320001, for a 2007 model it starts with 420001, for a 2008 model it starts with 520001. Some John Deere 4320 Tractors have a 4x4 MFWD 4WD chassis, but there are also some with a 4x4 HFWD 4WD (optional) chassis, all equipped with hydrostatic power steering. They also have differential mechanical wet disc brakes. The type I 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 540 rpms. The John Deere 4320 has an open center hydraulics system with a 10.3 gal [39.0 L] capacity. The pump does the job pushing 12 gpm [45.4 lpm] fluids in the hydraulics system.
