PROBLEM TO BE SOLVED: To provide the subject loading platform structure representing an overhang loading platform designed to retreat from a projected mode to retracted mode in order to, for example, avoid an obstacle even if loaded with tea bags as truckload, lessen the vertically loading/unloading work for tea bags to a minimum and thus diminish working burden as a whole. SOLUTION: This loading platform structure has such a scheme that the frame 20 of a traveling machine unit 2 to travel astride a tea ridge A with a tea plucking machine unit 3 is equipped with cutting blades 30 so as to face on the top surface of the tea ridge A to make a tea reaping operation is equipped with an overhang loading platform 11 to be loaded with tea bags 5 packed with reaped tea leaves so as to overhang from above the frame 20 both sideways of the traveling machine unit 2, wherein the overhang loading platform 11 is designed to run to a retracted mode with the sideward overhang obviated through rising movement toward the center of the machine frame while maintaining loading action and to a lift-mode as a result of its upward movement.
