<p>The machine comprises a supporting frame (1) carrying an engine (2), on the shaft (3) of which is mounted the driving pulley (4) of a belt drive. Its driven pulley (5) is mounted on an intermediate shaft (6) mounted in a support unit (7) hingedly connected to the frame (1) of the machine. The support unit (7) consists of a reduction gearbox whose driving gear (14) is connected to the driven pulley (5). Each of the power take-off shafts (11, 12) is kinematically connected to one of the gears (14, 15) of the reduction gearbox. On the frame (1) is mounted a spring (16) interacting with the support unit (7) through a link gear.</p> |
