John Deere B Extra Hydraulic Notes
Hydraulic flow note
The John Deere B should be matched to implements that fit its 8.9 GPM hydraulic-flow range.
Hydraulic pressure note
The John Deere B’s hydraulic pressure is listed at 1,000 psi, which is lower-pressure; flow still decides attachment speed while pressure affects force.
Rear remotes / SCV note
Rear remotes / SCVs are mentioned, but the exact count is not clearly confirmed in the scraped data.
For hydraulic implements, match the implement to the available hydraulic flow (33.7 L/min (8.9 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 B uses a closed-center hydraulic setup, so compatibility depends on both the attachment and valve configuration.
Hydraulic fluid capacity note
The John Deere B’s hydraulic fluid capacity is listed as 4 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.
