John Deere 310SL Backhoe Loader: Current-Production Heavy-Duty Super L

In production from 2017 forward, the 310SL is a heavy-duty backhoe loader built for modern jobsite efficiency - a balanced blend of horsepower, hydraulic force, and operator-focused design. Part of the celebrated JD Super-series, the 310SL pairs Tier 4 Final emissions with electrohydraulic joystick controls and AutoShift transmission options.

Where the 310SL fits in the JD backhoe line

The 310SL is the Super-L variant of JD’s current-production 310 backhoe loader - running alongside the standard 310L from 2017 forward. Same EPA Tier 4 Final PowerTech engine, same DPF + SCR aftertreatment, same sealed pressurized cab - paired with the heavier-duty structural components, more aggressive hydraulic settings, and equipment packaging that defines the Super-series.

For contractors spec’ing a new heavy-duty mid-class backhoe today, the 310SL is JD’s answer. The platform combines current-production emissions compliance with the structural reinforcement and production-grade hydraulics needed for contractor work.

JD 310SL Backhoe Loader - Quick Specs

Production: 2017 - Present
Class: Heavy-Duty Mid-Class Backhoe Loader
Engine: JD PowerTech (EPA Tier 4 Final)
Aftertreatment: DPF + SCR (DEF)
Controls: Electrohydraulic Joystick
Transmission: Power Shuttle or AutoShift Option
Front Tool: Hydraulic Loader (Aggressive Hydraulics)
Rear Tool: Center-Pivot Hydraulic Backhoe
Standard Variant: JD 310L
Predecessor: JD 310SK (Super K)

What the SL configuration adds vs. the standard 310L

Upgraded structural components. Heavier-duty loader arms, reinforced backhoe boom and stick, beefier swing tower components.
More aggressive hydraulics. Higher operating pressure and flow settings for production cycle times.
Heavier-duty stabilizers. Larger stabilizer leg cylinders and reinforced footpads.
AutoShift transmission option. Electronically-controlled multi-speed transmission with automatic shifting under load.
Production-grade hardware. Upgraded pin and bushing sizes at high-wear backhoe pivot points.
Shared with 310L: Tier 4 Final PowerTech engine, DPF + SCR aftertreatment, sealed pressurized cab, electrohydraulic joystick controls, monitor display.

Tier 4 Final aftertreatment - service implications The 310SL’s DPF and SCR systems are reliable when fed clean fuel and quality DEF, but they require attention. DEF tank must stay topped up. DPF will request periodic high-temperature regenerations. NOx sensors fail occasionally and trigger derate conditions. Factor aftertreatment service into the maintenance budget on Super L machines.

Engine, hydraulics, and drivetrain

The 310SL’s Tier 4 Final PowerTech diesel drives either a refined power shuttle or AutoShift transmission into planetary final drives. Engine, fuel system, aftertreatment, and cab components match the standard 310L - cross-fitment is broad in those categories. Hydraulic settings, structural backhoe components, and SL-specific pin/bushing assemblies are Super-series specific.

Common service items on the 310SL

Aftertreatment: DPF cleaning service, DEF dosing units, NOx sensors, DPF pressure sensors, SCR catalyst service.
Heavy-duty backhoe components: Swing tower pin kits (SL-specific sizing), stabilizer leg cylinders, boom/stick/bucket pin kits.
Engine internals: JD PowerTech Tier 4 Final rebuild kits - pistons, rings, sleeves, bearings, gaskets.
Fuel system: Common-rail injectors, high-pressure fuel pump, lift pump, fuel filters, water separator.
Engine electronics: ECU, sensors, harnesses, monitor display.
Electrohydraulic controls: Joystick assemblies, pilot control valves, control modules.
AutoShift transmission (equipped configs): Transmission internals, electronic controls, shift solenoids.
Hydraulics: Pump rebuilds, loader cylinder seal kits, backhoe cylinder seal kits, control valves, hoses.
Cooling system: Radiator, water pump, EGR cooler, thermostat, hoses.
Power shuttle (non-AutoShift): Shuttle clutch packs, control valves, hydraulic actuation components.
Drivetrain: Axle seals, final drive gears.
Cab: Cab glass, weather seals, door parts, seat, A/C parts.

What to verify before ordering

Serial number. Match parts to the machine serial.
SL vs. standard 310L. Backhoe structural and hydraulic parts differ between Super L and standard 310L.
Power shuttle vs. AutoShift. Verify transmission configuration before ordering - internals do not interchange.
Engine serial. PowerTech Tier 4 Final internal parts must match the engine serial.
Aftertreatment configuration. DPF and SCR part numbers can vary across the production run.
Loader configuration. Standard, quick-attach, and specialty bucket configurations had different cylinder and mounting specs.
Backhoe configuration. Standard reach vs. extendable boom configurations differ in cylinder bore and stroke.
Drivetrain configuration. 2WD and 4WD/MFWD configurations have different front axle and transfer case parts.

Why the 310SL sets the current JD heavy-duty benchmark

The 310SL represents JD’s current state of the art in the heavy-duty mid-class backhoe loader - Tier 4 Final emissions, electrohydraulic joystick controls, AutoShift transmission option, SL-specific structural reinforcement, and the operator-experience ergonomics customers expect on a current-production machine. For contractors buying new in this class, the 310SL is the JD answer.

Maintenance priorities on a 310SL: clean fuel (Tier 4 Final common-rail tolerates no contamination), DEF quality (poor DEF damages SCR catalyst), DPF service intervals, AutoShift fluid changes on schedule, hydraulic seal replacement as cylinders age, and engine rebuilds when wear demands. Broken Tractor maintains parts coverage across the current 310SL and the broader 310 Super-series family.
