John Deere 6120 Extra Hydraulic Notes
| Hydraulic flow note | With about 25 GPM implement flow, the John Deere 6120 sits in the high-flow row-crop hydraulic range and is best suited to multiple SCVs, larger implements and heavier hydraulic demand. |
|---|---|
| Hydraulic pressure note | The John Deere 6120’s hydraulic pressure is listed at 2,900 psi, which is strong tractor hydraulic pressure; flow still decides attachment speed while pressure affects force. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | System type matters on the John Deere 6120: closed-center affects how hydraulic flow and pressure are delivered to valves and implements. |
| Hydraulic fluid capacity note | The John Deere 6120’s hydraulic fluid capacity is listed as 55 qt (13.8 gal); check the operator manual before servicing because capacity can change with transmission, hydraulic options and market. |
Official information note
Mistakes do happen. Hydraulic flow, pump flow, implement flow, pressure, rear remote / SCV setup and fluid capacity can change by year, market, transmission, pump option, loader package and hydraulic package. Please check the operator manual and official deere.com website for official information.
