John Deere D Extra Hydraulic Notes
| Hydraulic flow note | For hydraulic work, the key number on the John Deere D is 17.6 GPM implement flow; that points toward larger loaders, rear remotes and more demanding implements, depending on pressure and valve setup. |
|---|---|
| Hydraulic pressure note | Hydraulic pressure on the John Deere D is 650 psi, but hydraulic performance depends on pressure and flow together. |
| Rear remotes / SCV note |
|
| Hydraulic system type note | The John Deere D’s hydraulic system type is open-center, which is simple and common on many compact and utility tractors. |
