On the hill overlooking Rocklands Reservoir, the locals have set up several pieces of agricultural equipment for permanent display. This one is a stump jump plough, originally invented 1876 in South Australia by Richard Bowyer Smith (1837-1919).
An ordinary plough couldn’t cope with constantly hitting rocks or stumps from recently cleared fields, so Mr Smith came up with a blade system that kicked up out of the way when it hit an obstacle, and which could be dropped down again, by hand.
In the following years, others manufactured the stump jump ploughs, some having as many as 12 blades. The flexibility was added to other types, including disc harrowers. It would’ve been informative if these pieces of machinery at Rocklands had little plaques, saying what they were, but I was able to find out easily enough.
Thanks for looking.
