Increasing production of livestock products requires a radical improvement of fodder production on farms and, above all, the procurement of stem fodder as such, ensuring the completeness of cattle feeding. Modern technologies and technical means of forage harvesting allow to perform high-quality work in agro-technical terms.
It is noted that haymaking, as well as other fodder, provides a systematic, comprehensive approach to the organization of work, staffing a set of technical means, their preparation for work, the collection and subsequent storage of feed.
The purpose of the research is to substantiate the peculiarities of the preparation of technical means for the procurement of leaf and stem materials for hay for the current state of technology in Ukraine and the world.
In the scientific work the peculiarities of preparation of technical means for harvesting hay from legumes and legume-cereal mixtures are considered. It is noted that to obtain high-quality hay should be widely used technical means that accelerate the drying of grass in the field: conditioners, tedders, rakes, and for drying hay - ventilation systems with heated air. The basic measures, adjustment and preparation of mechanization means at mowing, flattening, agitation and harvesting of hay are substantiated.
It is noted in the work that increasing the compression force of the rollers of the mower E-303 helps to accelerate the drying of the roller mass of the clover. It is established that the use of roller mower conditioner allows to get the weight for hay 2-3 days after mowing, which is less per day than mowing without weight conditioning. The obtained results allow to recommend the installation of rollers with an edge in front of the edge for accelerated drying of the mass, which allows to accelerate the drying process by 9-12 hours.
