John Deere X166 Extra Hydraulic Notes
Hydraulic flow note
The John Deere X166’s total flow is higher than implement flow, so use the implement-flow number when matching hydraulic tools and SCV-driven equipment.
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 (4.5 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 X166: open-center affects how hydraulic flow and pressure are delivered to valves and implements.
Hydraulic fluid capacity note
For maintenance, the John Deere X166’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.
