ABSTRACT:
A scraping adapted for attachment to the raking head of a conventional rake includes a substantially elongated adapter body defining a body first longitudinal edge, an opposed body second longitudinal edge and a pair of substantially opposed body longitudinal ends. The adapter body is configured so as to provide a substantially longitudinally extending scraping section adjacent the body first longitudinal edge. The scraping adapter also includes a body-to-head attachment structure for attaching the adapter body to the raking head with the head base and body longitudinal axis in a parallel relationship relative to each other and the scraping section positioned opposite the rake tines.
