An apparatus is provided for spreading aggregate material on ground. The apparatus includes a body 12, an engine 14 carried by the body, motive structure 18 powered by the engine to move the apparatus along the ground. A hopper 20 is associated with the body and is constructed and arranged to receive aggregate material from a source of aggregate material. Dispensing structure 24, associated with the hopper, is constructed and arranged to dispense aggregate material from the hopper to the ground. Wheel structure 30, carried by the body, is constructed and arranged to be movable between an inoperative position, wherein the motive structure is in a ground engaging position and the wheel structure is in a position so as not to engage the ground, and an operative position, wherein the wheel structure is in a ground engaging position and the motive structure is in a position so as not to engage the ground. A hitch structure 32, carried by the body, is constructed and arranged to be coupled to a vehicle so that the apparatus can be towed by the vehicle when the wheel structure is in the operative position thereof.
