MOBILE AGRICULTURAL MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a mobile agricultural machine having a belt tension clutch capable of preventing a belt from being detached and positively connecting/disconnecting power. SOLUTION: A suction fan driving system for performing power transmission to a suction fan includes a fan driving belt 52 wrapped around between a second driving pulley 29, and a fan pulley 37 provided on the upper side thereof. The belt tension clutch 53 keeps a tension roller 55 in rolling-contact with the fan driving belt 52 from an inner peripheral side toward the outer peripheral side thereof. A belt guide 61 for guiding the fan driving belt 52 from the outer peripheral side is provided at a tip end of a tension arm 56 supporting the tension roller 55. The belt guide 61 guides the fan driving belt 52 from the outer peripheral side during clutch connection and supports disconnection of the clutch by pressing the fan driving belt 52 to the inner peripheral side during clutch disconnection.
