The Multidrive 6185 is powered by a 185hp John Deere engine. Based near the Giants Causeway, Bushmills, Co Antrim, James Richmond runs Causeway Agri alongside a sheep enterprise. However, not being your typical agricultural contractor, James specialises in liquid fertiliser application and crop spraying. Background Having originally started out as a general agricultural contractor, James moved into the area of crop spraying during the 1990s. At this time, spraying potato crops with acid was the done thing and required specialist gear. Given that few farmers at the time were equipped with the suitable machinery, James had a niche offering which saw him spray on farms in all corners of the country.
