John Deere 6425 Extra Hydraulic Notes
Hydraulic flow note
With about 17.4 GPM implement flow, the John Deere 6425 sits in the utility tractor hydraulic range and is best suited to larger loaders, rear remotes and more demanding implements, depending on pressure and valve setup.
Hydraulic pressure note
The John Deere 6425’s hydraulic pressure is listed at 2,538 psi, which is normal utility-tractor pressure; flow still decides attachment speed while pressure affects force.
Rear remotes / SCV note
Rear remotes / SCVs depend on the tractor’s hydraulic package and options.
For hydraulic implements, match the implement to the available hydraulic flow (17.4 GPM), not just the number of remotes.
Check the operator manual or hydraulic package because SCV count can change by year, market and trim package.
Hydraulic system type note
System type matters on the John Deere 6425: closed-center affects how hydraulic flow and pressure are delivered to valves and implements.
Hydraulic fluid capacity note
Hydraulic fluid capacity on the John Deere 6425 is 58.1 qt (14.5 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.
