Abstract: The technology disclosed herein relates to a maintenance vehicle. The vehicle has a vehicle frame, drive wheels rotatably coupled to the vehicle frame and a prime mover coupled to the vehicle frame. The prime mover is in operative communication with the drive wheels. A hopper assembly is pivotably coupled to the vehicle frame. The hopper assembly has a hopper having a discharge opening and a spreader disk adjacent to the discharge opening. The hopper assembly is pivotable about a pivot axis between a maintenance position and an operating position. The spreader disk is positioned vertically below the discharge opening when the hopper assembly is in an operating position.
