ABSTRACT:
A mechanism for cutting of stalks or stems of plants and/or grass-like vegetation, in an environmentally safe manner, has counter-blades arranged on a circular path and rotary blades positioned above the counter-blades. The ratio of the surface area of the counter-blades actually taking part in the cutting and the surface area of the free spaces between them, in relation to each other, is smaller than a value of one. A distance of "h" between the counter-blades and the rotary blades is a value between 0-2 mm, and the peripheral speed of the rotary blades is between 10 and 50 m/sec.
