John Deere 8RX 490 Extra Hydraulic Notes
Hydraulic flow note
The John Deere 8RX 490’s implement flow figure is about 84 GPM, so hydraulic attachment choice should be based on flow demand, not horsepower alone.
Hydraulic pressure note
At 2,958 psi, the John Deere 8RX 490’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 (84 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 8RX 490: open-center affects how hydraulic flow and pressure are delivered to valves and implements.
Hydraulic fluid capacity note
The John Deere 8RX 490’s hydraulic fluid capacity is listed as 50 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.
