There are three classes of World Style ploughing at Mullahead and there is a cup for each class.
- World Style (Open) – Stanley Cup
- World Style (Confined) – McDonagh Rose Bowl
- Word Style Reversible – Mrs Annet Memorial Cup
The competition is fierce as the ploughing is judged on points. These points are added to the competitors score sheet and at the end of the ploughing season the competitor with the highest score has the chance to represent Northern Ireland at the World Ploughing Championships anywhere in the world
