John Deere 140 Extra Hydraulic Notes
Hydraulic flow note
The John Deere 140’s implement flow figure is about 21 GPM, so hydraulic attachment choice should be based on flow demand, not horsepower alone.
Hydraulic pressure note
Hydraulic pressure on the John Deere 140 is 610 psi, but hydraulic performance depends on pressure and flow together.
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 (21 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 140’s hydraulic system type is closed-center, which is built for higher-pressure hydraulic control than a basic open-center setup.
Hydraulic fluid capacity note
For maintenance, the John Deere 140’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.
