    Abstract: The apparatus of this invention includes a long rod and a short rod, each of desired length, and each with a rake on one end and a hoe on the other end. Both rakes are of the same novel construction with three tines uniquely arranged to enable a workman mounted on a ladder to pull leaves in a conventional gutter toward himself and beneath spikes holding the gutter to a roof. The method of this invention enables a workman to draw leaves toward himself from both sides of the ladder without having to move the ladder.
