John Deere STX38 Extra Hydraulic Notes
| Hydraulic flow note | The John Deere STX38’s implement flow figure is about 6.5 GPM, so hydraulic attachment choice should be based on flow demand, not horsepower alone. |
|---|---|
| Hydraulic pressure note | The John Deere STX38’s hydraulic pressure is listed at 1,000 psi, which is lower-pressure; flow still decides attachment speed while pressure affects force. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | The John Deere STX38’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 | Hydraulic fluid capacity on the John Deere STX38 is 3 qt (0.8 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.
