JCB 3DX Series Compared: 3DX, 3DX Plus, Xtra & Super Backhoe Loaders Explained

JCB’s 3DX backhoe loader lineup offers a wide range of machines engineered for performance, fuel efficiency, and comfort. Each variant—3DX, 3DX Plus, 3DX Xtra, and 3DX Super—addresses different site demands while sharing a common core: the robust JCB Stage 5-430 engine, tested for over 2 lakh hours in Indian conditions. Let’s break down how each model stands out.

1) JCB 3DX: Efficient Performer, Built for Every Day

The JCB 3DX runs on a 37 kW (49 hp) Stage 5-430 engine. It focuses on saving fuel while retaining productivity. With a dig depth of 4.77m, shovel capacity of 1 cu. m, and dump height of 2.74m, this model suits standard construction work.

Why choose it: Because it cuts fuel use by up to 10%, thanks to features like the variable displacement hydraulic pump, multiple working modes, and e-waste gate turbocharger. Operators stay comfortable with reduced cabin noise and ROPS/FOPS protection. Maintenance stays simple through remote diagnostics and extended service intervals.

2) JCB 3DX Plus: Power-Packed & Versatile

The 3DX Plus raises power to 55 kW, torque to 440 Nm, and efficiency with up to 12% less fuel consumption. Available in 2WD, 4WD, and 4WD High Dump options, it fits a broader range of applications.

What’s better: It boasts a shovel capacity of 1.1 cu.m, a bucket size of 0.26 cu.m, offers modes for loading, roading, and economy, and incorporates Auto Stop and Idle features to save fuel. The 4WD variant gives you 15% more output and 20% better fuel efficiency. The high dump bucket lifts dump height by 45%, ideal for re-handling and feeding hoppers. The Plus variant prioritizes adaptability, which makes it ideal for contractors who juggle multiple job types.

3) JCB 3DX Xtra: Dig Deeper, Load More

The 3DX Xtra . With a dig depth of 5.05m, dump height of 2.93m, and bucket size of 0.3 cu. m, this variant supports demanding excavation and bulk material handling.

Its 55 kW engine delivers 440 Nm of torque and 10% better fuel economy. The Easy Shift Gear, Semi-Kick Down Switch, and Smooth Ride System make operations smoother and faster.

Why consider it: The larger shovel (1.1 cu.m), the rotating gear knob for effortless shifts, multiple working modes, and the auto idle and auto stop feature all contribute to reducing unnecessary fuel burn. This machine suits sites where deeper digging and higher loading volumes matter. For site managers wanting efficiency with reach, the Xtra delivers.

4) JCB 3DX Super: All-Rounder with More Control

The 3DX Super combines strength and technology for jobs needing everything—dig depth, torque, stability, and versatility.

You get 4WD as standard, a 6-in-1 multipurpose bucket, a 5.05m digging depth, a 2.93m dump height, and a 0.3 cu. m bucket. Its Smooth Ride System, Easy Shift Gear, and Semi-Kick Down give the operator better control, even on uneven surfaces.

Why does it stand out? Best torque in class: 440 Nm, multiple working modes for task-specific fuel optimization, ROPS/FOPS safety, and low in-cabin noise for long-hour jobs. Maintenance remains simple with remote diagnostics, 4,000-hour oil intervals, and open-loop crankcase ventilation that eliminates filter changes.

Final Thoughts

All four JCB 3DX models share durability, smarter fuel use, and operator-focused design. But your worksite needs, loading height, and terrain type should decide the best pick. If you want all-terrain performance and added control, go for the 3DX Super. For digging deeper and loading more, choose the 3DX Xtra. If you need a value-driven workhorse, start with the JCB 3DX. If versatility across job types matters most, the 3DX Plus fits best.
