John Deere 6605 Extra Hydraulic Notes
| Hydraulic flow note | The John Deere 6605’s implement flow figure is about 26.6 GPM, so hydraulic attachment choice should be based on flow demand, not horsepower alone. |
|---|---|
| Hydraulic pressure note | At 2,900 psi, the John Deere 6605’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 6605 uses a closed-center hydraulic setup, so compatibility depends on both the attachment and valve configuration. |
| Hydraulic fluid capacity note | The John Deere 6605’s hydraulic fluid capacity is listed as 52 L (13.7 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.
