One of the things that's interesting about agriculture is the evolution of machinery and engineering over time.
For the first few rice harvests in the Murrumbidgee Irrigation Area, wheat harvesters were used.
These harvesters, or headers, weren't that successful. A pioneer grower augmented the header with an internal combustion engine to deal with the tough rice straw. Headers at the time were pulled by horses and the movement of the wheels on the ground were used to make the machinery work. The use of the secondary engine allowed the header to successfully separate the rice from the straw.
The first engines were steam-driven and with the wisps of steam coming from the top, they were given the nickname of 'Coffee Pots'
