Cutting industrial hemp at different stages of maturity is rather a complicated operation because of the hard fibre in its stalks, great specific cutting resistance, as well as high crop capacity and great length of the stalks. In order to find harvesters that are suitable for these purposes, comparative experiments have been conducted. The process of cutting hemp is most stable when finger bar mowers are used. The rotary (disk) mowers are of little use for cutting hemp due to the tendency of the stalks to wind up around the shafts and other rotating details. It is economically purposeful to use the fingerbar mower TEBECO Beagle 3.2 when the areas to be harvested are less than 50 ha but on smaller areas good results can be achieved by the duplex mower KD-210.
