T Alun Jones & Son will extend its New Holland territory in July 2027.
The dealer, which currently covers south-west Wales, will expand into south-east Wales as the exclusive provider for New Holland sales, service and parts support.
David Rapkins, commercial business unit director for UK and ROI, said: “We would like to thank David Evans Agricultural Ltd for its valued commitment and service to New Holland customers over many years. Our priority throughout this transition is to ensure continuity of support for customers in Southeast Wales.
“T Alun Jones & Son has a strong reputation for customer care and technical expertise, and we are confident the team will provide the high standards of sales, service and parts support that New Holland customers expect.”
