In the early days of settlement in South Australia there was a general shortage of farm labourers to manually harvest crops. In 1943 a competition was held in search of a design for a reaping machine. The eventual winner was John Ridley, whose machine was known as The Stripper. There was some contention as to the true inventor; John Wrathran Bull claimed he had submitted a design in the contest and Ridley's machine was an adaption.
Over the years the machine was modified and improved; it was used as the primary method of harvesting until the early 1900's. I am not sure as to the age and make of the harvester photographed.
