The follow-up to the popular 88–118 models was named the Medion. The 88-series was dropped altogether because even the smallest Medion matched the former 98. The concave length grew from 3.9 to 4.4 meters, and each set of concaves was fitted with two straw-walker axles. The 340 was the only model in the range with six walkers. Otherwise, the differences between models were largely limited to engine output. All engines were MB’s 6.4-liter, intercooled units. In its first years on the market, the 310 was also delivered to Finland equipped with a Perkins engine.

The upper and lower sieves moved in opposite directions, and each sieve consisted of two parts for easier handling. The grain elevator was now the same as those used in the Lexion series. Grain-tank capacity had increased to 5.8 m³ (58 hl), and the diameter of the unloading auger was also larger than before. The hydraulic system was built around Linde components. The front axle was beefed up and fitted with disc brakes. The cab was largely identical to the Lexion-style cab used on the 88 VX, and noise levels were quoted at 78 dB. Prices were noticeably higher than those of the predecessors.
