Abstract: A lawn broom includes a rotary drum having a plurality of sweep elements secured thereon, with each of the sweep elements including a flat mounting strap which extends through an opening provided in the drum. Each mounting strap is provided with an elongated slot and a plurality of mounting pins carried by brackets within the drum slidably extend through the slots provided in the straps to secure the sweep elements on the drum. The pin and slot connections permit the sweep elements to move radially of the axis of rotation of the drum and to tilt from side to side so that the sweep elements, over the entire length of the drum, can follow the contour of the lawn surface.
