John Deere 310L Backhoe Loader: Current-Production Tier 4 Final

In production from the mid-2010s forward, the 310L is a Tier 4 Final powerhouse that blends fuel efficiency, advanced hydraulics, and strong loader and backhoe breakout forces. Engineered for performance on busy jobsites, the 310L improves on the K-generation with refined emissions, a sealed pressurized cab, and the latest electronic controls.

Where the 310L fits in the JD backhoe line

The 310L succeeded the 310K as the mid-class industrial backhoe loader in JD’s current production lineup. The L generation brought EPA Tier 4 Final emissions compliance, refined hydraulics, electrohydraulic joystick controls as the standard configuration on most builds, and a modernized sealed pressurized cab.

For customers spec’ing a new mid-class industrial backhoe today, the 310L is JD’s answer. The Super-L variant (310SL) runs alongside as the heavier-duty option in the same chassis family.

JD 310L Backhoe Loader - Quick Specs

Production: Current Production
Class: Mid-Class Industrial Backhoe Loader
Engine: JD PowerTech (EPA Tier 4 Final)
Aftertreatment: DPF + SCR (DEF)
Controls: Electrohydraulic Joystick
Drivetrain: Refined Power Shuttle
Predecessor: JD 310K
Heavier Sibling: JD 310SL (Super L)

What changed from the 310K to the 310L

Engine. EPA Tier 4 Final JD PowerTech diesel. DPF and SCR aftertreatment with DEF dosing. The full modern emissions configuration.
Aftertreatment. DPF and SCR with DEF dosing - adds DEF tank refills, NOx sensor service, and SCR catalyst monitoring to the maintenance schedule.
Hydraulics. Advanced hydraulic flow distribution, refined pump efficiency, and improved breakout force at both loader and backhoe buckets.
Cab. Sealed pressurized operator station with improved climate control, full-color monitor display, refined electrohydraulic joystick controls as standard equipment.
Service access. Refined daily-service points, sampling locations, and aftertreatment service intervals.

Tier 4 Final aftertreatment - service implications The 310L’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 L-gen machines.

Engine, hydraulics, and drivetrain

The 310L’s PowerTech Tier 4 Final diesel drives a refined power shuttle transmission into planetary final drives. The engine runs cooled EGR, DPF, and SCR with DEF dosing - the full modern emissions configuration. Hydraulics deliver more breakout force than any previous 310 generation, and the electrohydraulic joystick controls give operators precise control with reduced fatigue.

The loader circuit and backhoe circuit share a refined load-sensing pump arrangement that prioritizes flow where the operator commands it. Standard reach and extendable-dipperstick backhoe configurations were both offered, and bucket configurations on the loader side ranged from standard to multi-purpose and quick-attach builds.

Common service items on the 310L

What to verify before ordering

Serial number. Match parts to the machine serial.
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.
Joystick equipment. Electrohydraulic-joystick configurations have specific control components - verify against build sheet.
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.
Cab vs. ROPS canopy. Glass, weather seals, A/C parts, and door parts differ.

Why the 310L remains a current-production pick

The 310L represents JD’s current state of the art in the mid-class industrial backhoe - Tier 4 Final emissions, advanced hydraulics, electrohydraulic joystick controls, sealed pressurized cab, and the operator-information ergonomics customers expect on a current production machine. For customers buying new in this class, the 310L is the JD answer.

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