Abstract: A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure, a left hub that is mounted on a left hub mount arm, and a right hub that is mounted on a right hub mount arm. A broom is mounted between the left hub and the right hub. An outer tube is attached to the rear of the broom enclosure and to one of the left and right hub mount arms. An inner tube has a fixed end that is attached to the left or right hub mount arm to which the outer tube is not attached. The inner tube also has a free end that is adapted to slide within the outer tube. A linear actuator is attached between the broom enclosure and the left or right hub mount arm to which the fixed end of the inner tube is attached. The linear actuator is adapted to move the hub mount arm to which it is attached between an inner position in which the broom is engaged with the left hub and the right hub and an outer position in which the broom is disengaged from one or both of the left hub and the right hub.
