Abstract:
1. A sweep brush assembly for a surface maintenance machine, said sweep brush assembly comprising: a rotatable surface engaging brush being connected to the surface maintenance machine by a selective coupling, said selective coupling providing the brush between a first operational orientation and a second displaced orientation, said second displaced orientation being laterally displaced away from a longitudinal centerline of the machine as compared to the first operation condition, said coupling including an arm connected at a proximal end to the machine by a pivot and said brush being coupled to an electric motor connected to a distal end of the arm, during forward movement of said machine said electric motor being closer to a front of said machine than said pivot, wherein the distal end of the arm, electric motor and brush are rotated in a lateral direction away from the machine centerline as the brush is provided in its second displaced orientation; and a hopper in operative relation to the brush to receive debris from the surface when the brush is in its first operational orientation wherein said brush blocks removal of said hopper, said hopper being removable from the surface maintenance machine when the brush is in its second displaced orientation.
