FIELD: agriculture.
SUBSTANCE: group of inventions relates to agricultural machine industry and can be used in harvest machinery. The knife head assembly of the agricultural machine harvester contains a prolate bar for fastening of the knife head, bearing and connection assemblies. The knife head assembly is designed with a possibility of connection with engine for transmission of the driving force. The prolate bar includes multiple first holes for intake of fasteners for fixing with the unit for razors and the second viahole for intake of the fastening element. The bearing assembly includes the bearing holder and ring bearing with an internal viahole. The ring bearing is held in the bearing holder, and its viahole is in alignment with the second viahole for intake of the fastening element. The connector assembly is designed with a possibility of fastening of the driving element and fixing of the bearing assembly in the viahole of the connector assembly.
EFFECT: removal of the razor assembly from the head assembly can be efficiently performed by means of disconnecting of a small amount of fasteners, that ensures to an operator a possibility of easy dismantling or replacement of the razor assembly.
