British Agricultural Revolution
Andrew Meikle (5 May 1719 – 27 November 1811) was a Scottish mechanical engineer credited with inventing the threshing machine, a device used to remove the outer husks from grains of wheat. He also had a hand in assisting Firbeck in the invention of the Rotherham Plough. This was regarded as one of the key developments of the British Agricultural Revolution in the late 18th century. The invention was made around 1786, although some say he only improved on an earlier design by a Scottish farmer named Leckie.
