Claims

[Scope of utility model registration request]

A belt for power transmission is wound between an output pulley connected to an engine and an input pulley connected to a transmission, and a tension arm is supported by a tension arm rotatable around the axis of a support shaft. In a mobile agricultural machine having a tension roller that approaches and separates from the outer circumferential surface of the belt by rotation of a tension arm, a rotating member that is connected to a drive unit and can freely rotate is provided, and the rotating member is engaged with the rotating member. An engaging body that is movable between an engaging position and a disengaging position for releasing the engaged state is attached to the tension arm, and an operating switch for operating the drive unit is attached to the operator's hand on the handle of the mobile agricultural machine. A belt transmission safety device for a mobile agricultural machine, characterized in that a safety lever is attached to the handle, the safety lever being connected to the engaging body via a wire and moving the engaging body to a disengagement position.
