John Deere 4555 Extra Hydraulic Notes
Hydraulic flow note
With about 32.8 GPM implement flow, the John Deere 4555 sits in the high-flow row-crop hydraulic range and is best suited to multiple SCVs, larger implements and heavier hydraulic demand.
Hydraulic pressure note
Hydraulic pressure on the John Deere 4555 is 2,500 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 (32.8 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
The John Deere 4555 uses a closed-center hydraulic setup, so compatibility depends on both the attachment and valve configuration.
Hydraulic fluid capacity note
The John Deere 4555’s hydraulic fluid capacity is listed as 18.5 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.
