John Deere 4955 Extra Hydraulic Notes
Hydraulic flow note
The John Deere 4955’s total flow is higher than implement flow, so use the implement-flow number when matching hydraulic tools and SCV-driven equipment.
Hydraulic pressure note
The John Deere 4955’s hydraulic pressure is listed at 2,530 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 (28.5 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 4955: open-center affects how hydraulic flow and pressure are delivered to valves and implements.
Hydraulic fluid capacity note
Hydraulic fluid capacity on the John Deere 4955 is 10 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.
