About the John Deere 9120

The John Deere 9120 Tractor was manufactured between 2002 and 2007. Sometimes, the parts compatibility is determined by the serial number of your John Deere 9120 Tractor, and that info should be listed on the part fit notes. If you don't have the serial number of your tractor, you can find it on the top-left of rear hinge member. The serial number starts from 1001 for a 2002 model, from 10001 for a 2003 model, from 20001 for a 2004 model, from 30001 for a 2005 model, from 40001 for a 2006 model, from 50001 for a 2007 model. They also have hydraulic wet disc brakes. The type III 3-point hitch is very reliable, capable to lift 13,871 lbs [6291 kg]. It is also worth noting that the independent rear PTO runs at 1000 rpms. The John Deere 9120 has a closed center pressure/flow compensated hydraulics system with a 27 gal [102.2 L] capacity. The pump does the job pushing 30 gpm [113.6 lpm] fluids in the hydraulics system.
