Abstract
Abstract A working vehicle comprising an engine mounted on a vehicle frame, a control box mounted on the vehicle frame, and a radiator erected on the vehicle frame between the engine and the control box structure. A dust-proof space is defined by the control box, the radiator and a hinged hood covering the engine. Elastic sealing elements are arranged between opposite lateral sides of the control box and the radiator, and between an upper end of the radiator and the hood. The hood in a closed position presses upon the upper elastic elements to provide an additional support for the radiator and to seal the dust-proof space.
