The deal comes as JCB celebrates 10 years of engine manufacturing.
The engines, made by JCB Power Systems in Derbyshire, will be Ecomax 55kW/74HP Stage IIIB models. Initially they will power the Terex TA6 and TA6S site dumpers.
JCB chief executive Graeme Macdonald said: “The engine supply contract is a major milestone for the JCB Power Systems business. It is one of the biggest engine supply deals in the company’s history and is testament to reliability and efficiency advantages that the JCB Ecomax engine offers customers.”
JCB began producing engines at its plant in Foston, Derbyshire at the end of 2004. Engine production was extended to India in 2011. To date JCB has produced 350,000 engines globally. JCB engines now power more than 70% JCB’s own products as well as a growing number of machines manufactured by others.
