John Deere 45R Extra Hydraulic Notes
| Hydraulic flow note | With about 35.3 GPM implement flow, the John Deere 45R sits in the high-flow row-crop hydraulic range and is best suited to multiple SCVs, larger implements and heavier hydraulic demand. |
|---|---|
| Hydraulic pressure note | At 2,500 psi, the John Deere 45R’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 45R’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 45R is 23.5 qt (5.9 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.
