John Deere 68 Extra Hydraulic Notes
Hydraulic flow note
For hydraulic work, the key number on the John Deere 68 is 18.8 GPM implement flow; that points toward larger loaders, rear remotes and more demanding implements, depending on pressure and valve setup.
Hydraulic pressure note
Hydraulic pressure on the John Deere 68 is 2,901 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 (18.8 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 68: closed-center affects how hydraulic flow and pressure are delivered to valves and implements.
Hydraulic fluid capacity note
Hydraulic fluid capacity on the John Deere 68 is 3.5 qt (0.9 gal), but the correct oil type and fill/check procedure should still come from the official manual.
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.
