Chaser Bin

From Wikipedia, the free encyclopedia

A chaser bin is a trailer towed by a tractor with an in-built auger system, usually with a large capacity (around 15 Tonnes is average). The bin is used to transport grain over fields from combine harvester to lorry or further tractors which are used to cover larger, road based distances. The use of a chaser bin permits the harvester to operate continually without the need for stopping to unload. These bins usually require tractors with large power outputs and are popular on the large open fields of the United States and Australia, though usage in Europe is increasing.
