PROBLEM TO BE SOLVED: To provide a moving agricultural machine in a simple and compact structure, which drives and stops a suction fan while transmitting a motive power to drive system auxiliaries. SOLUTION: A first driving pulley 27 and a second driving pulley 29 are provided to the crank shaft 26 of an engine 9, and an auxiliary driving belt 51 is wound around the first driving pulley 27, a water pump pulley 35, and an alternator pulley 50. A fan driving belt 52 is wound around the second driving pulley 29 and a fan pulley 37 arranged outside the machine, and a belt tension clutch 53 is provided to the fan driving belt 52. When the crank shaft 26 rotates, a drive system auxiliaries 30 and 31, and a suction fan 45 are driven via the auxiliary driving belt 51 and the fan driving belt 52, respectively. By cutting off the belt tension clutch 53, the suction fan 45 is stopped while the drive system auxiliaries 30 and 31 are still in drive. COPYRIGHT: (C)2011,JPO&INPIT |
