John Deere 8400 Extra Hydraulic Notes
Hydraulic flow note
With about 30 GPM implement flow, the John Deere 8400 sits in the high-flow row-crop hydraulic range and is best suited to multiple SCVs, larger implements and heavier hydraulic demand.
Hydraulic pressure note
Hydraulic pressure on the John Deere 8400 is 2,900 psi, but hydraulic performance depends on pressure and flow together.
For hydraulic implements, match the implement to the available hydraulic flow (30 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
System type matters on the John Deere 8400: closed-center load-sensing affects how hydraulic flow and pressure are delivered to valves and implements.
Hydraulic fluid capacity note
The John Deere 8400’s hydraulic fluid capacity is listed as 37 gal; check the operator manual before servicing because capacity can change with transmission, hydraulic options and market.
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.
