John Deere 20A Extra Hydraulic Notes
Hydraulic flow note
For hydraulic work, the key number on the John Deere 20A is 9 GPM implement flow; that points toward normal loader use, small hydraulic implements and general utility work.
Hydraulic pressure note
Hydraulic pressure on the John Deere 20A is 2,250 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 (9 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 20A’s hydraulic system type is open-center, which is simple and common on many compact and utility tractors.
Hydraulic fluid capacity note
Hydraulic fluid capacity on the John Deere 20A is 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.
