John Deere 6120M Extra Hydraulic Notes
| Hydraulic flow note | The John Deere 6120M should be matched to implements that fit its 21.2 GPM hydraulic-flow range. |
|---|---|
| Hydraulic pressure note | Hydraulic pressure on the John Deere 6120M is 2,900 psi, but hydraulic performance depends on pressure and flow together. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | System type matters on the John Deere 6120M: closed-center pressure-flow compensated affects how hydraulic flow and pressure are delivered to valves and implements. |
| Hydraulic fluid capacity note | For maintenance, the John Deere 6120M’s hydraulic fluid capacity matters more than flow rate because it affects oil changes, filter service and refill quantity. |
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.
