John Deere SST18 Extra Hydraulic Notes
Hydraulic flow note
The John Deere SST18 should be matched to implements that fit its 25.4 GPM hydraulic-flow range.
Hydraulic pressure note
Hydraulic pressure on the John Deere SST18 is 2,000 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 (25.4 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 SST18 uses a open-center hydraulic setup, so compatibility depends on both the attachment and valve configuration.
Hydraulic fluid capacity note
Hydraulic fluid capacity on the John Deere SST18 is 6.8 qt (1.7 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.
