FIELD: agricultural engineering. SUBSTANCE: combine has housing and tangential-flow thresher mounted in crosswise position within the housing. Thresher has cylinder and sectioned deck, which is formed by frame with two transverse planks and two longitudinal arced lateral planks and by three grate arced sections, which are in contact one with the other. Frame has longitudinal arced webs disposed in the vicinity of sites of contact between arced sections. The sections are installed for displacement, withdrawal of middle section with subsequent withdrawal of remaining sections upon displacement of these sections along transverse planks of frame to the initial position of the middle section. The sections are withdrawn in circumferential direction with respect to drum axis through front opening of combine housing. EFFECT: increased efficiency by providing adequate conjugation between frame members and deck sections. 7 cl, 9 dwg
