John Deere 9RX 770 Extra Hydraulic Notes
| Hydraulic flow note | With about 56 GPM implement flow, the John Deere 9RX 770 sits in the very high-flow hydraulic range and is best suited to large hydraulic implements and high-demand farm equipment where SCV flow matters. |
|---|---|
| Hydraulic pressure note | At 2,900 psi, the John Deere 9RX 770’s hydraulic system pressure matters most for lift force, cylinder force and loader response. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | The John Deere 9RX 770 uses a closed-center hydraulic setup, so compatibility depends on both the attachment and valve configuration. |
| Hydraulic fluid capacity note | For maintenance, the John Deere 9RX 770’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.
