Bertie Cahill has been contracting all his life, and judging by his love of machinery and impressive yard of kit, he has no plans to hang up the keys just yet. Based just outside the town of Ballingarry, Co Limerick, Bertie has seen huge changes in mechanisation as a contractor since he started his own contracting business 43 years ago. Silage was always, and continues to be, his main contracting enterprise.
