Granted I'm not a plow engineer so I really don't know everything that goes into one, but how complicated can one plow really be...
Complicated enough...
Following an initial trial, Richard, then in business with Clarence at Kalkabury (Arthurton) on Yorke Peninsula, exhibited two prize-winning versions of a stone- and stump-jumping plough at the agricultural show at Moonta in November 1876. The Farmers' Weekly Messenger accurately forecast that Smith's invention had the potential to 'cause a complete revolution in tilling uncleared land'. The mechanism allowed the shares to glide over stumps which otherwise required grubbing, a laborious and costly process. He failed, however, adequately to secure his rights under the Patents Act of 1877 and prosperity eluded him.

Of course, if he invented it today, he and his descendants would have prosperity guaranteed for as long as they could buy lawmakers...
