John Deere 9400 Extra Hydraulic Notes
| Hydraulic flow note | The John Deere 9400’s implement flow figure is about 44 GPM, so hydraulic attachment choice should be based on flow demand, not horsepower alone. |
|---|---|
| Hydraulic pressure note | Hydraulic pressure on the John Deere 9400 is 2,900 psi, but hydraulic performance depends on pressure and flow together. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | The John Deere 9400’s hydraulic system type is closed-center, which is built for higher-pressure hydraulic control than a basic open-center setup. |
| Hydraulic fluid capacity note | The John Deere 9400’s hydraulic fluid capacity is listed as 26 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.
