On the basis of the research a prototype of clover huller-scarifier КС-0.2 was developed. The machine is
used for extraction of seeds from the wad of clover and other legumes and cereal grasses as well as for scarifica-
tion of hard grass seeds. The machine includes frame, body, horizontal barrel, deck, batch hopper, device for sup-
plying material to a machine, pipe for input and output, extension, holder for bag, the drive mechanisms, electric
equipment. Research purpose - to determine the optimal load-speed modes of clover huller-scarifier КС-0.2 (sup-
plying of a material q and the frequency of barrel rotation n). Wad of clover Kirovsky-159 having humidity
12…14% was used as initial material for study action of clover huller-scarifier in mode of seed thrashing. Large
impurities, small impurity and seeds without shells were removed previously from wad of clover. Machine per-
formance was evaluated by the degree of seed thrushing  and seed crushing d. For scarification of Seeds of
galega corresponding to State standard 52323-2005 for reproduction of seeds for seed purpose was used as initial
material at studing of scarifying mode. The quality of scarification was evaluated by degree of seed scarification
С and degree of change in number of germinated seeds П. Regularities were identified of changes in
agrotechnical parameters of a prototype machine clover huller-scarifier КС-0.2 from load-speed modes. It is de-
termined that degree of seed thrushing  higher than 95% and crushing of seeds d less than 1.5% are achieved
with supplying q = 0.2…0.3 t/h and frequency of barrel rotation n = 1000…1200 min-1. Degree of scarification of
seeds C more than 99% and the degree of change in the number of germinated seeds П = 42.9…43.2% are
achieved with supplying q = 0.2…0.3 t/h and frequency of barrel rotation n = 950…1000 min-1 .
Key words: clover huller, seeds, scarifier, thrushinf of grass seed, scarification of seeds
