Surface drying apparatus and method

A method of drying a ground surface, comprising;

• a) taking air into a blower;
• b) passing said air through a heater which heats said air by burning fuel directly in the flow of said air, wherein the controls for said heater are powered by an onboard generator;
• c) directing said air through a duct toward said surface without recirculating said air, while
• d) moving said blower, heater, and duct along said ground surface.

A mobile hot air generating apparatus comprising:

• a structural frame;
• a first reservoir of a first fuel mounted on said structural frame;
• a heater mounted on said structural frame and capable of receiving and burning said first fuel;
• electrical controls mounted on said structural frame, said electrical controls controlling the reception and burning of said first fuel by said heater;
• a generator mounted on said structural frame, said generator providing electricity to said electrical controls;
• a second reservoir of a second fuel mounted on said structural frame;
• an internal combustion engine mounted on said structural frame and receiving and consuming said second fuel, said internal combustion engine driving said generator;
• a blower mounted on said structural frame, said blower blowing non-recirculating air through said heater, said blower being driven by said internal combustion engine;
• a duct for directing said non-recirculating air blown through said heater by said blower as said non-recirculating air exits said heater;
• and,
• means for moving said structural frame, said means comprising at least one wheel attached to said structural frame and a hitch extending from said structural frame, said hitch being adapted to connect to a self-propelled vehicle propelled by its own internal combustion engine.
