The Boxer is a machine for carrying, metering, mixing and conveying seed and/or fertiliser. The Boxer is driven in the three-point linkage of the tractor. Complementary machines can be used to spread the seed/fertiliser carried in the Boxer. The Boxer is often used in combination with a semi-mounted cultivator. With the aid of the cultivator tine, this combination is used to place fertiliser in the soil in a targeted manner, while an e. g. covercrop can be spread behind the roller of the cultivator. Special features of the Boxer: Combination options with various soil cultivation implements for incorporating fertiliser, or with a wide variety of tillage combinations for sowing and simultaneous fertilising. Here, cost savings can be realised, as existing technology only needs to be modified, but can otherwise be used without restriction. (In the case of Köckerling implements, this can be combined with the Allrounder -profiline- up to 7.50 m working width, the disc harrow Rebell -profiline- and Vector).
