The combination of a mower and thresher in one piece of equipment is still one of the most revolutionary developments in the agricultural world. Hiram Moore and his helping hand, John Hascall, are deemed to be the inventors of the first version of the combine harvester, which used to be pulled by horses. In 1836 they applied for a patent for this machinery. The first version had a roller at the front which was covered in highlighted spikes that pulled the wheat in the direction of the mower. After it had been cut off, the wheat was processed in a thresh-cylinder. The vibrating filter then sorted the wheat from the chaff. After this had been done the wheat fell into a sack. That was the beginning of the combine harvester as we know it. However, the combine harvester only really became ready to go into production after many experts had tried their hand, and sometimes failed horribly, at developing it further. The name which is still connected to combine harvesters today is Cyrus McCormick. For a long time he tried to produce a moving combine harvester in his workshop in Virginia. However, he gave up at one point and his sons took over the task. The workers who made the developments were all intent on improving the technology so that it was suitable for everyday work. Yet they also managed to fit a steam engine into the combine harvester. A 12 meter long cutting tool and headlights already belonged to the standard fitting at this point. Even then these quick machines managed to cover an area of 40ha within just one day. The reason that the combine harvester didn’t take on in Europe as it did in the USA and Canada was due to the fact that their way of doing things, especially the manner of sowing, was different. After the Second World War the combine harvesters became more popular in Germany and in 1965 there were 165,000 vehicles in use. The technology, which was still based on the first ideas that the inventors had, kept on developing. For example, the thresher was, over the years, expanded. After the tangential threshing process had been developed, in which the threshing cylinder is placed transverse to the driving direction, New Holland and IH 1975 introduced the so-called axial process onto the market. In this process the wheat is pulled inwards parallel to the driving direction. This development caused a great deal of discussion amongst the farmers. Many farmers complained that the straw is heavily burdened through this process. This meant that the tangential process was never really left behind. However, manufacturers developed better tangential processes due to the complaints. Over time, it became standard that the combine harvester has a cabin and an air conditioning unit. Today, the manufacturers of combine harvesters tried to stand out from their competition by developing larger chaff containers and by also generating more motor power.
