Claas brought out the successor model to the Matador in time for the 2002 harvest. It was the beginning of the Medion series. The Claas Medion 310 combine harvester was the smallest model in this series. Claas equipped it with the OM 906 LA, its inline 6-cylinder engine. With 6.4 litre displacement, it reached a rated output of 150 k/W or 204 HP. The Claas Medion 310 combine harvester was designed for smaller land parcels, in which the width of the harvested crop is between broad beans and clover seed. The working width is 3.60 to 9.0 m, the folding cutter-bar brings it to 4.5 m, when it is folded, the transport width is 3 m. The Claas Medion 310 combine harvesters have a threshing system which consists of drum in a flange design, which has a width of 1320 mm and a diameter of 450 mm. The residual grain separation takes place via five shaker trays with four shaker drop steps. The cleaning is carried out via an indoor fan, which can be adjusted from the cab. The Claas Medion 310 combine harvesters also support 3D cleaning. It allows for an optimal distribution of the crop on the upper sieve on slopes of up to 20% gradient, without compromising the throughput. The grain tank in the Medion 310 holds 5.800 litres and has a discharge capacity of 72 l/s. As with the Vista Cabs in the Lexion models, the driver has a clear overview. The ergonomically-placed switches, levers and pedals allow the driver to handle the Claas Medion 310 combine harvesters in an intuitive way.
