Farmer John stumps the doubters with international technology success
Another Australian farmer is following in the footsteps of the inventors of the stump-jump plough by achieving international renown for his ingenuity for down-to-earth solutions for problems encountered by producers globally. Queensland farmer John Bucknell’s hydraulic bolts are now used around the world in applications such as nuclear reactors, boilers, turbines and mining and energy equipment where speed, accuracy and even, precise fastening of multiple sets of bolts is required. The idea originally stemmed from his desire to find a quicker and more secure way to fasten bolts used to tighten gang bolts on large disc ploughs on his family’s property near Nindigully, Queensland (about 500km west of Brisbane). Just like brothers Richard and Clarence Smith of Yorke Peninsula who invented the stump jump plough in 1876 to allow farmers to cultivate land without removing rocks and stumps, John used his disc plough to break in new country, ready for production, after his father converted the property from grazing to agricultural production, predominantly wheat. A better disc plough solution At the time, disc ploughs used scalloped discs mounted in gangs turning in order to chop up the ground. But these were prone to breaking if they encountered a stone, stump, or other obstacle. To replace them involved using a sledgehammer to loosen and tighten the large nut of the centre shaft of the gang. The whole gang had to be taken to replace broken discs, then the whole assembly had to be rebuilt once it was fixed… only for the plough to hit another obstacle 100 metres on, and the time-consuming process had to start again. Frustrated by this laborious process, he developed sets of hydraulic nuts and bolts to do the job of fastening and unfastening disc assemblies simultaneously, far faster and more securely than the old way of twisting […]
