The module has PTO system 5 mounted on separate small frame 6. Frame 1 is provided with U-shaped subframe 7 which, complete with frame 1 and small frame 6, forms a two-tier structure rigidly held together by the housing of the power transmission 4. The small frame 6 is connected both with frame 1 and subframe 7 by connecting members in the form of flanges 8 with bolt holes. The flanges of the upper tier of the structure are offset forward relative to the flanges of the lower tier. The subframe is made up of two longitudinal side members interconnected by a crossbar and provided with brackets in the middle for connection of subframe 7 with the housing of power transmission 4. The power unit comprises front and rear 15 couplings mounted, respectively, on small frame 6 and on the crossbars of subframe 7 and comprises a vertical plate with conical pins and grips on its side surfaces. EFFECT: improved design. 4 cl, 4 dwg
