Updated
The original John Deere 310 is a backhoe loader. Deere's three-page separates gasoline and diesel engines, two backhoe circuits, and early and later units. A model name and photograph from a seller leave those distinctions unresolved.
Use the sheet to identify which specification row needs checking. It cannot establish the equipment fitted to a particular machine from the number 310 alone.
Start with the engine and transmission
Page 1 provides a compact starting point for an original 310:
| Item | What the sheet records |
|---|---|
| Engine family | John Deere 300 Series |
| Fuel and displacement | Gasoline or diesel; each listed as three cylinders, 164 cu in (2.7 L) |
| Rated output | 50 SAE net hp at 2,500 rpm |
| Transmission | Collar shift with hydraulic reverser; eight forward and four reverse speeds |
Record the machine's full identification and the installed engine's identification separately. A seller's diesel description can be compared with the sheet, but it does not establish an engine's originality or condition. The sheet's footer reads 24MAR97; that document date does not date the machine.
Why the 9405 and 9500 rows cannot be combined
The hydraulic section on has separate 9405 and 9500 backhoe circuit headings. Both contain early and later boom-raise rows, but the pattern differs:
| Backhoe circuit heading | Relationship between the printed boom-raise rows |
|---|---|
| 9405 | The later-unit value is higher than the early-unit value. |
| 9500 | The early- and later-unit values are the same. |
The extract gives no serial-number boundary for those labels. Treat an unidentified backhoe as an unresolved configuration, rather than choosing whichever row looks newer. Obtain its identification and the applicable manual before selecting a service specification. The two headings do not establish that either backhoe is installed on a machine offered for sale or that an attachment swap is approved.
Keep the conditions attached to hydraulic figures
Deere lists a closed-center system. Its minimum used-pump flow figure is 23 gpm at 2,000 psi and 2,200 rpm. Quoting only 23 gpm drops the pressure, engine speed and minimum-used qualification that make the row interpretable.
The cycle-time table is also conditional: it specifies fast idle and hot oil. A time reported without matching conditions cannot be compared directly with that table. These are document-reading checks; this guide does not provide a pressure-adjustment or machine-testing procedure.
Resolve the sheet's gaps before relying on a number
One dimension needs particular care: page 1 prints transport length as 12 ft 5 in alongside 3.05 m. Those values do not convert to each other. Do not silently choose one as the machine's verified transport length; resolve the discrepancy with applicable documentation and the machine's actual configuration before planning transport.
The refers readers to codes at the front of the book. That key is outside this extract. Capacity rows and letter codes therefore do not, by themselves, identify an approved replacement fluid. This sheet is also insufficient support for an oil-change interval or a filter shopping list.
Keep suffix models and lawn tractors separate
Deere publishes separate documents for the , , and . Keep the complete model designation when finding a manual; later-model maintenance material does not establish an original 310's requirements.
The . Deere's 350 and 350B crawler documents concern different machines again. Mower-deck widths, lawn-tractor engine advice and crawler specifications do not describe the original 310 backhoe loader.
Ask for the configuration the sheet leaves open
For an original 310 listing, ask for the full machine identification, engine identification and fuel type, backhoe identification, and documentation establishing the applicable early or later version. Mark an unreadable or missing identifier as unknown. Match the machine and backhoe identifiers to the applicable document before relying on a specification.
