PROBLEM TO BE SOLVED: To enable an accurate loading operation even when an object is loaded into a hopper from a low position in a mobile processing machine with a hopper. SOLUTION: In a mobile processing machine provided with a hopper 11a for throwing an object, a pole 23 projecting upward from an inner wall of the hopper is provided. The height of the upper end of the pole is higher than the height of the upper end of the hopper. Even if the hopper is at a higher position than the operator, the positional relationship of an object above the hopper with respect to the hopper can be accurately grasped by using the pole as a mark.
