John Deere 6145J Extra Hydraulic Notes
Hydraulic flow note
For hydraulic work, the key number on the John Deere 6145J is 26.4 GPM implement flow; that points toward multiple SCVs, larger implements and heavier hydraulic demand.
Hydraulic pressure note
The John Deere 6145J’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 (26.4 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
The John Deere 6145J uses a closed-center pressure-flow compensated hydraulic setup, so compatibility depends on both the attachment and valve configuration.
Hydraulic fluid capacity note
Hydraulic fluid capacity on the John Deere 6145J is 26.4 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.
