John Deere GX345 Extra Hydraulic Notes
| Hydraulic flow note | For hydraulic work, the key number on the John Deere GX345 is 4.5 GPM implement flow; that points toward loader work, steering and simple implements, but not high-demand continuous hydraulic attachments. |
|---|---|
| Hydraulic pressure note | At 2,000 psi, the John Deere GX345’s hydraulic system pressure matters most for lift force, cylinder force and loader response. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | System type matters on the John Deere GX345: open-center affects how hydraulic flow and pressure are delivered to valves and implements. |
| Hydraulic fluid capacity note | The John Deere GX345’s hydraulic fluid capacity is listed as 4.5 qt (1.1 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.
