Wrights of Twycross Operate over 40 Bunning trailed muck spreaders in order to apply over 600,000 tonnes of Bio-solids each year. We have worked with G.T. Bunning & Sons over the past 10 years to make sure that we get the desired spread pattern to meet the demands of all types of Bio-Solids. Operating different types of spreaders gives us the advantage to situate the best suited spreader for each area.
