The SS-4000 walk-behind rotary broom’s centrally driven brush allows it to work against curbs, walls, and other obstacles from either the left or right side. The plow attachment rides above the ground while the bristles clear low spots without damaging the surface, making the unit ideal for use on rough ground, pavers, decorative concrete, and other applications and conditions, including wet and deep snow.
