Mark Davies, of Welshy Contracting, had donated his time and the use of his latest machine, a Case bulldozer capable of laying cables, earth wire and mag slab in one operation. It was the first job for the half-million-dollar vehicle since he got it.
A member of the Methven Vintage Club, he was just one of many people and businesses who donated time, sponsorship or equipment to the projects, Mr Griffiths said.
They included Rainer Irrigation and Methven electrician Greg Anderson.
New power meters for use by exhibitors at the annual show on March 17 were also installed.
At the same time, a permanent irrigation system was laid, bringing water from the Barrhill Chertsey Irrigation Scheme from the nearby rugby grounds through the rodeo grounds to water the main show ring and the north ring.
About 500m of pipe was laid.
Owners and users of the showgrounds such as the association, the Methven Rodeo Club, the Methven Vintage Club, and the Methven Pony Club combined to finance and complete the projects.
