Abstract
A power broom assembly includes a vehicle, a rotatable broom mounted to the front of the vehicle, and an airblast assembly mounted to the front of the vehicle above the broom to suck up an overspray of material which has been swept up by the broom. An airblast assembly for use in the power broom assembly includes a casing, a cross flow blower in the casing, and at least two outlets in the casing which are selectively openable and closeable by flexible wall portions which are movable radially inwardly and outwardly to substantially change the inner contour of the casing. A drive system of the power broom assembly includes a first transmission unit which has first and second output shafts, and a second transmission unit which includes an input shaft. At least the first and second output shafts of the first transmission unit and the input shaft of the second transmission unit are aligned along a single axis.
