A push broom head is provided having a substantially rigid base, leading edge, upper and lower surface, central vertical axis, plurality of rows of seats, and a plurality of tufts of bristles. The head includes a leading edge row(s) of tufts of a first type closest the leading edge and a plurality of rows of a second type. The length of the second type of tuft bristles is longer than the length of the first type and the number of rows of tufts of the second type exceeds the first type. The axis of each tuft forms an angle relative to the base's central vertical axis. Preferably, when not in contact with the sweeping surface, the angle of attack of the second type of bristles differs by row and/or the angle of the leading row of tufts exceeds 10 degrees in a forward direction relative to the central vertical axis.
