John Deere 322 Extra Hydraulic Notes
| Hydraulic flow note | The John Deere 322 separates implement flow from total hydraulic flow: 6.3 GPM is the more useful number for rear remotes and hydraulic implements, while 12.4 GPM includes the wider system total. |
|---|---|
| Hydraulic pressure note | At 2,000 psi, the John Deere 322’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 322 uses a open-center hydraulic setup, so compatibility depends on both the attachment and valve configuration. |
| Hydraulic fluid capacity note | Hydraulic fluid capacity on the John Deere 322 is 1.6 gal, but the correct oil type and fill/check procedure should still come from the official manual. |
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.
