John Deere 6120E Extra Hydraulic Notes
Hydraulic flow note
The John Deere 6120E’s implement flow figure is about 20 GPM, so hydraulic attachment choice should be based on flow demand, not horsepower alone.
Hydraulic pressure note
The John Deere 6120E’s hydraulic pressure is listed at 2,900 psi, which is strong tractor hydraulic 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 (20 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
The John Deere 6120E’s hydraulic system type is open-center, which is simple and common on many compact and utility tractors.
Hydraulic fluid capacity note
Hydraulic fluid capacity on the John Deere 6120E 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.
