Studies were conducted to improve the effi ciency of feed production technology in the form of high-moisture fl attened conserved grain by means of harvesting wheat with the use of stripping tools without threshing. The research objectives included an assessment of the quality and energy consumption of a single-rotor stripper header, depending on its operating modes, for harvesting high-moisture wheat plant mass. The implementation of resource-saving technologies for the feed production in the form of wet fl attened grain is constrained due to restrictions in traditional harvesters for direct grain harvesting in the phase of the beginning of wax ripeness. To solve the problem of effi cient harvesting of high-moisture grain, stripping working tools were proposed. The use of a single-rotor stripper header was justifi ed. To assess the technological effi ciency of stripping high-moisture wheat plant mass, experimental studies were conducted with the use of a bench model of a single-rotor stripper header. The results of changes in the quality indicators and the energy assessment of stripping of Novosibirsk-31 variety wheat stands were obtained, whereby the average grain moisture was 40% and the rotation frequency of the header stripping rotor was in the range of 330-650 rpm. A comparative assessment of the results of stripping wheat stands at the beginning of wax and hard ripeness was carried out. The research results showed the feasibility of using a single-rotor stripper header for harvesting the productive part of cereal crops at the beginning of wax ripeness for fodder purposes, including fl attening and subsequent conservation as the most rational way of processing high-moisture grain. The use of a stripper header as a forage harvester adapter will increase the effi ciency of resource-saving technologies for harvesting highmoisture grain and will expand agrotechnical period for harvesting grain for feed purposes.
