John Deere 1840 Extra Hydraulic Notes
| Hydraulic flow note | The John Deere 1840 should be matched to implements that fit its 10.3 GPM hydraulic-flow range. |
|---|---|
| Hydraulic pressure note | Hydraulic pressure on the John Deere 1840 is 2,900 psi, but hydraulic performance depends on pressure and flow together. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | The John Deere 1840’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 | The John Deere 1840’s hydraulic fluid capacity is listed as 39 L (10.3 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.
