John Deere 40 Extra Hydraulic Notes
Hydraulic flow note
The John Deere 40 separates implement flow from total hydraulic flow: 23 GPM is the more useful number for rear remotes and hydraulic implements, while 33 GPM includes the wider system total.
Hydraulic pressure note
At 1,080 psi, the John Deere 40’s hydraulic system pressure matters most for lift force, cylinder force and loader response.
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 (23 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 40 uses a closed-center hydraulic setup, so compatibility depends on both the attachment and valve configuration.
Hydraulic fluid capacity note
For maintenance, the John Deere 40’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.
