In this article, we introduce the generalized harmonic Koebe function and find its coefficient bounds. We obtain radii of fully starlikeness and convexity for convex combinations two generalized univalent harmonic mappings. We also obtain radii of fully starlikeness and convexity for convolutions of two generalized univalent harmonic mappings.
