The deal also includes 40 JCB Loadall telescopic handlers and six backhoe loaders made at JCB’s World HQ in Rocester.
Several of the machines have already been delivered and the JCB wheeled excavator models are carrying groundworks as part of the M25 motorway widening scheme.
Lynch Plant Hire director, Robert Lynch said: “We have offered JCB Loadalls and backhoe loaders for over fifteen years.
“When it came to expanding our tracked and wheeled excavator fleet we conducted trials of the leading models using our own operators to carry out the tests.
“We ultimately chose the JCB machines as the operator feedback was very, very positive, particularly regarding smoothness of controls and stability when digging.
