The cutting device has upper and lower cutting blades (32,33) with a separating plate between them. A counter-blade (31) is fixed to the chassis of the machine, and the upper and lower cutting blades are driven with an alternative linear movement. Each upper and lower blade has a set of individual blades separated between each other. The counter-blade has a U-shaped fixed counter-blade with each arm of the U-shape defining an individual counter-blade comprising an upper portion and a lower portion. The upper portion is arranged above the upper cutting blade and the lower portion is arranged below the lower cutting blade. A shearing effect is created between each upper and lower cutting blades and the fixed counter-blade. An independent claim is given for method of cutting a plant stem.
