Stump jump plough designSouth Australian, Robert Bowyer Smith, developed the first Stump Jump Plough in 1876 and took out a patent the following year. The plough made clearing Mallee scrub for cultivation easier and faster. The technology was not, at first, well accepted and he allowed his patent to lapse, whereupon other manufacturers began to capitalise on the idea. Smith was formally recognised as the plough’s inventor in 1882, receiving a bonus payment from the Parliament and a government land grant.
