Abstract
A fan shaped rake fitted with a plurality of individual prongs pivotably mounted to the end of the rake pole, together with a sleeve slidably fitted about the rake pole which may be slid to a first position to fold the prongs to lie along the axis of the pole and to a plurality of extended positions which open the rake prongs in fan wise fashion.
