Moline motor plough, c 1917.
© Science Museum / Science & Society Picture Library
This motor plough was built by the company that later became Minneapolis Moline, one of the pre-eminent names in American tractor manufacture. With its twin-cylinder, horizontally opposed engine it is one of the earlier versions of such machines. Normally the plough would be situated trailing behind the front wheels, but the machine is here shown set up for conventional haulage. Some other makes of motor plough could also be converted thus.
