Abstract
A push broom head comprising a base with a leading edge and a trailing edge separated by a width of the base; and tufts of bristles extending from a surface of the base; the tufts of bristles being arranged in rows of bristles of decreasing stiffness from the leading edge to the trailing edge of the base, with a leading row of very stiff bristles and a trailing row of bendable bristles, thereby combining increased ease of handling by a user for an efficient sweeping action, the leading rows loosening and moving heavier particles and the trailing rows loosening and moving finer particles not acted upon by the stiff leading rows.
