Abstract: An asphalt sealant material is heated within an insulated box-like container supported by a front caster wheel and a pair of thin disk-like steel side wheels. A push-type handle bar projects rearwardly and upwardly from the container which has an inner bottom wall sloping downwardly to a side discharge tube. A burner tube extends through a surrounding heater tube located within the lower portion of the container, and a heat exchange oil is confined within the annular space defined between the tubes. A propane fuel tank is supported by a platform projecting rearwardly from the container and is connected by a flexible hose to a nozzle located at the front or the rear of the burner tube. The rear of the burner tube connects with a vertical exhaust pipe, and the rear of the heater tube connects with an oil fill tube.
