Concept modelling:- The JCB backhoe has been very popular in India, and even the
term ‘JCB’ has come to denote the ‘backhoe’. Thus, the concept marketing of the JCB
has been a huge success, with the customer looking up to the features provided in the
JCB model as a benchmark. Operator Training One of the factors affecting the industry
is the lack of skilled operators who have the knowledge of operational techniques of a
backhoe. JCB conducts regular training programmes for operators.

6. Re- manufacturing: Service Exchange JCB has come up with a scheme in which the
customers can bring an old machine to the service centre and have it remanufactured to
the latest specifications at 50% less than new parts. The company claims that all the
major components of JCB machine, including the engine, are designed such that they
can be remanufactured.
