The JCB 140X is a tracked excavator from JCB's X Series. At a maximum operating weight of 15,275 kg it is the lightest of the five. For this model JCB highlights larger hydraulic pipes and strong bucket tearout; both affect digging productivity, because less pressure loss in the lines lets more of the pump output reach the cylinder.
JCB's X Series has been on the market since 2018. For the five models covered here JCB gives these maximum operating weights: 140X at 15,275 kg, 150X at 17,861 kg, 220X at 24,743 kg, 245XR at 28,009 kg and 370X at 39,888 kg. According to the manufacturer every model in the series went through thousands of hours of extreme endurance testing. The operating weight given is a maximum and depends on the equipment chosen.
JCB excavators – other models: from the 3CX backhoe loader to the 3CX Hydrogen, mini excavators of the C-1 and Z-2 series as weight class, Perkins and Dieselmax engines
This page gathers the JCB excavators and backhoe loaders the register could not assign to a named range: from the early backhoe loaders 2D and 3D through the legendary 3CX – the most-built backhoe loader in JCB's history since 1980 – to the 3CX Hydrogen, a hydrogen-powered prototype of the early 2020s, plus mini, midi and crawler excavators of the C, X and Z series. On the mini and midi excavators, the number in the designation traditionally states the approximate operating-weight class in tenths of a tonne, so the 19C-1 weighs around 1.9 tonnes and the 90Z-2 around 9 tonnes. Engines on the classic backhoe loaders came mainly from Perkins, JCB's long-standing engine partner, before the brand switched to its own Dieselmax engines from 2004.

The register lists here 40 versions, mostly with diesel engines, from the compact mini and micro excavators of the 8000 and C-1 series to the large excavators of the X series plus backhoe loaders, compact loaders and skid-steer models.
With this range JCB covers practically the whole earthmoving programme, from the mini excavator for garden and utility work to the backhoe loader as a distinctly British machine used on building sites, in municipal work and in agriculture worldwide; the backhoe loader ranks among the most recognisable construction machines of all.
On used examples, operating hours and the condition of the engine and hydraulic pumps, undercarriage or tyre wear, the condition of the boom, bucket and attachment lock, and the tightness of the cylinders all matter; spare parts run through the JCB dealer network, and on older backhoe loaders additionally through independent Perkins workshops.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
