The history of the baler goes back to the middle of the 19th Century. The first model was built at this time in America but only managed to establish itself a decade later. Originally, after the harvest the hay was loaded onto a wagon and transported to the barns. The loose straw consumed a great deal of space and the storage proved to be complicated and expensive. It was due to this that the idea came to press the straw in order to store it in a way which saved space and money. In 1980 in Germany the manufacturer Laaß built the first straw baler of its kind. Further manufacturers followed suit and also tried to improve the technology. Thus, in the course of time an operating system with a steam engine was developed and later a system with a stationary motor. At the beginning, wire was used to hold the compressed straw together. Today, the balers, which were introduced in 1940 as the new manner of compressing, use binding twine to complete this process. Finally, the procedure of picking up the straw and binding it were merged together in 1940 with the help of the so-called Pick-Up-Baler. This tool could not however, be pulled by horses (as was normal in those days) but had to rather be pulled by a tractor. Due to the fact that tractors were not that common, the Pick-Up-Baler had a difficult start. A further important cornerstone for the development of the baler as we know it today was laid by the Vemeer company from Iowa who developed a new technique. All producers from that point on used this technique which involved the straw being rolled into bales in a chamber and then subsequently being compressed. After the introduction of this technique, the balers became more popular. This was due to the fact that they now only required one controlling person which saved a great deal of time and money. The newest development in the area of balers is the round silage baler. This technique is comparable with the fermentation process in a silo in so far as that the herbage is compressed and then enclosed in a PVC film. There are a multitude of manufacturers and models on the market today which leave the buyer spoilt for choice.
