An apparatus and method for quickly and effectively drying ground surfaces are disclosed and claimed. The invention has particular utility in the drying of a race track surface. The invention consists of a means for blowing air upon the surface, a means for heating the air and a means for moving the apparatus with respect to the surface to provide flexibility and control in the degree of drying/heating performed. The apparatus and method may be applied to a variety of surfaces including earthen (dirt) surfaces, concrete and asphalt. One of the objectives of the device is to enable the drying of a track surface such that the surface will not be damaged by overheating which can otherwise occur with other track drying devices applied to an asphalt surface in particular. The design of the invention makes specific use of enhanced turbulent air flow at the surface in order to improve performance over a purely laminar air flow.
