John Deere 3440 Extra Hydraulic Notes
Hydraulic flow note
For hydraulic work, the key number on the John Deere 3440 is 12.4 GPM implement flow; that points toward normal loader use, small hydraulic implements and general utility work.
Hydraulic pressure note
The John Deere 3440’s hydraulic pressure is listed at 2,466 psi, which is normal utility-tractor 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 (12.4 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 3440 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 3440’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.
