Abstract. The article presents the results of the experimental studies of haymaking machines. Technical and operational parameters are determined and the coefficients of shift time use for each machine - mowing machines, rakes, balers - are calculated. Taking into account the amount of work agro-technical terms and the actual hourly productivity of the aggregates used in this process are ascertained, and the optimal set of machines for hay harvesting in difficult terrain conditions of mountain haymaking is substantiated.
Key words and phrases: природный горный сенокос, косилка, грабли, пресс-подборщик, технико-эксплуатационные показатели, эффективная эксплуатация, natural mountain haymaking, mowing machine, rakes, baler, technical and operational parameters, efficient operation.
