It has played an enormous role. However, bulldozers of various types still have some shortcomings in carrying out earthmoving operations, mainly because bulldozers do not work after retreating and consume fuel. What’s more, they are not easy to get into the soil when shoveling soil. Few shovels push the earth to a certain extent, which has affected the distribution of the mechanical action. In order to solve this problem, many social organizations have adopted a manpower-assisted approach and organized dozens of labor forces.
