Abstract: A surface coating material applying and spreading apparatus comprises a forward and two rear drive wheels, with each of the three drive wheels being driven by a separate hydraulic motor independent of each other. A hydraulic circuit connects the three hydraulic motors of the drive wheels with a hydraulic pump, and communication between the pump and each of the motors is automatically controllable to drive one, two, or all three of the hydraulic motors and their associated drive wheels. The vehicle also comprises a spray bar assembly that is pivotally connected to a frame of the vehicle, and is pivoted to a raised and lowered position relative to the vehicle frame. The vehicle frame also releasably supports interchangeable rotating brush and wiper blade assemblies. The rotating brush assembly is universally pivotable horizontally and vertically from side to side, about the pivot connection to the vehicle frame.
