Three Farmet machines competed in a difficult cultivation match in the former Cidlina River bed: Triton 450 PS, a specialist in crop residue incorporation; Fantom 650 PRO, a light ploughshare cultivator and stubble plough; and Digger 3, a deep cultivator (chisel plough). The field where corn for grain grew was harvested with a combined harvester. Moreover, wild boars ate in the field and crushed it, which made the cultivation conditions harder. The extremely heavy soil did not allow for cultivation deeper than 17 cm. In spite of these conditions, we compared the work of 3 different machines.
