John Deere 855 Extra Hydraulic Notes
| Hydraulic flow note | With about 70 GPM implement flow, the John Deere 855 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 2,600 psi, the John Deere 855’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 855 uses a open-center hydraulic setup, so compatibility depends on both the attachment and valve configuration. |
| Hydraulic fluid capacity note | The John Deere 855’s hydraulic fluid capacity is listed as 4.5 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.
