John Deere SST15 Extra Hydraulic Notes
| Hydraulic flow note | For hydraulic work, the key number on the John Deere SST15 is 7.3 GPM implement flow; that points toward loader work, steering and simple implements, but not high-demand continuous hydraulic attachments. |
|---|---|
| Hydraulic pressure note | Hydraulic pressure on the John Deere SST15 is 790 psi, but hydraulic performance depends on pressure and flow together. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | The John Deere SST15’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 | For maintenance, the John Deere SST15’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.
