John Deere 1445 Series II Extra Hydraulic Notes
Hydraulic flow note
The John Deere 1445 Series II separates implement flow from total hydraulic flow: 12.5 GPM is the more useful number for rear remotes and hydraulic implements, while 20 GPM includes the wider system total.
Hydraulic pressure note
At 2,300 psi, the John Deere 1445 Series II’s hydraulic system pressure matters most for lift force, cylinder force and loader response.
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 (12.5 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 fluid capacity note
Hydraulic fluid capacity on the John Deere 1445 Series II is 9 qt (2.2 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.
