The Uni-System concept was among the more interesting farm machinery ideas introduced to the Irish market over the past 50 years. The idea was of a base power unit, meaning and engine and transmission that could be used to operate a combine harvester and then convert to a self-propelled type silage harvester. The aim was to give greater annual use to a basic power unit on the farm.One of the Ireland’s biggest farm machinery companies at the time, McGee of Ardee, introduced the Uni-System from the US under the Farmhand brand name. McGee’s were importers for the Farmhand range, which included tub feeders, tractor loaders and balers.
