Model stump jump plough

This is a model of a double furrow stump-jump plough made by Albert Arnold between 1882 and 1883. Stump-jump mouldboard ploughs were an Australian innovation and became the most sophisticated of all ploughs. After clearing the land of trees, the stumps and rocks left hidden in the ground destroyed the shares and mouldboards of many of the imported ploughs regardless of how strongly they were made.

The stump-jump plough was invented by Richard (Robert) Bowyer Smith of Kalkabury (Arthurton) on the Yorke Peninsula of South Australia in 1876. In that year he and his brother, Clarence Herbert Smith, constructed a three-furrow plough with, shares which worked independently of each other in a frame so that when any one of them struck a stump or rock it automatically rose, passed over the obstacle and re-entered the ground by way of a counter weight. Later in 1876 Smith exhibited a single-furrow stump-jump plough with a draught chain attached to drag the bottom back in the ground. The 'bridle draught' effect was further developed by W.M. May of Wallaroo and Heithersay of Peterborough in South Australia and soon became widely used on stump-jump ploughs.

Mr Arnold was the first to introduce the stump jump plough to NSW (from SA), in 1882, using this model to demonstrate the working of the implement.




Mr Arnold donated this model plough to the Museum in 1926. In 1929 he donated a group of objects (B538 to B552) to illustrate both the blacksmith's art and his own inventiveness and artistry.

Arnold was born in 1856 at Gawler in South Australia. While living in that state, he learned his trade as an apprentice, spent some time farming, and is said to have made improvements to the stump jump plough. He moved to Sydney in 1882 and worked for Joyner and Son in Paddington, where he might have made the model stump jump plough that he donated to the Museum in 1926 (object B526). From 1888 he worked at the railway workshops in Eveleigh, where he applied his inventiveness to making many metal objects including a folding railway carriage key (object B545), two NSW Railways monograms (objects B538 and B539) and a large machine for making springs. This machine served his employers well for many years, just as he had. In his retirement, he created representations of various Australian birds in iron in his backyard smithy.

When Arnold donated a group of objects to the Museum in 1929, he stated that his aim was to illustrate the blacksmith's art for visitors. To this end, the donation included three of his inventions (two combination tools, B544 and B549, and a bandage winding machine, B542), a group of miniature blacksmith's tools (B541) and other full-size tools. He seems to have been a man who loved, and took great pride in, the trade to which he applied himself for most of his life.
