Back in primary school days we learnt about some Australian inventions for the agricultural industry. Among those was the "stump Jump Plough" and the "Ridley Stripper". It was pleasing therefore to come across the Historic Engineering Marker for the Bull and Ridley Grain Harvesting Machines. The photo added to the Gallery is of Mrs y'stassie standing next to the marker and information board. Thanks Team MavEtJu for another very information cache in the series.
