John Deere 6140D Extra Hydraulic Notes
Hydraulic flow note
The John Deere 6140D separates implement flow from total hydraulic flow: 20 GPM is the more useful number for rear remotes and hydraulic implements, while 21.1 GPM includes the wider system total.
Hydraulic pressure note
The John Deere 6140D’s hydraulic pressure is listed at 2,828 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 6140D’s hydraulic system type is open-center, which is simple and common on many compact and utility tractors.
Hydraulic fluid capacity note
For maintenance, the John Deere 6140D’s hydraulic fluid capacity matters more than flow rate because it affects oil changes, filter service and refill quantity.
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.
