The JCB JZ140 is an extremely productive reduced tailswing tracked excavator.

A reduced tailswing design offers you greater levels of safety than a conventional excavator because manoeuvrability is superior, especially in restricted spaces.



A JCB JZ140 excavator’s reinforced boom and dipper is made of high tensile strength steel, with internal baffle plates for long life durability.

  • To ensure reliability; the JZ140’s EcoMAX T4F/Stage IV engine has been tested for 110,000 hours in 70 machines across the toughest applications and environments worldwide.
  • The high-strength undercarriage of the JCB JZ140 tracked excavator uses a fully welded X-frame construction for long-term durability even in the most demanding applications.
  • The JCB JZ140 tracked excavator’s high-strength rigid upper frame provides maximum durability and support, while its stiff durable door design offers you added strength and rigidity.


A reduced tailswing configuration is perfect for working in urban environments or where space is at a premium.

  • In short, because the JZ140's excavator tail movement is easier to predict and control, safety and operator confidence are increased significantly.
  • The JCB JZ140 excavator is fitted with a rear and side view camera as standard.
  • A 70/30 front screen split gives JCB JZ140 tracked excavators excellent front visibility. A clear view of the front right track provides easy, safe trench digging and manoeuvring.


Simultaneous tracking and excavating is smooth and fast with an intuitive multifunction operation. Proportional controls offer you precise command over attachments and in tasks where you need to perform fine adjustments.

  • A JCB JZ140 is a solid, stable work platform for fast cycle times, while a massive 92kN bucket tearout – with correspondingly fast cycle times - makes this excavator extremely productive in all applications.
  • There’s a full list of auxiliary pipework options including hammer, auxiliary, and low flow. For ultra versatility, these auxiliary options are available with proportional controls.


JCB SMART Control gives access to variable working modes with a manually selectable High Plus mode for ultimate productivity.

  • The JCB JZ140's 7" colour multi-function display is easy to read in all light conditions, provides instant operational information, and has a customisable home screen.
  • A climate control option offers a precisely controlled cab temperature with fresh or recirculated air. Demisting/defrosting functions keep a JZ140 excavator’s front window clear.
  • Our new basic tool select system (fitted as standard) allows the operator to set up the single direction auxiliary and hammer circuit to match the flow requirements. The selected flow is achieved by automatically adjusting the engine revs when the hydraulic service is operated.
