ABSTRACT:
Aquatic plants and their entangled roots can be removed from a lake or other body of water by pulling a lake rake out onto the lake, then pulling the lake rake, with a load of plants and their roots, back in to a central collection site on shore. Multi-purpose teeth of this rake are shaped and positioned to glide across the surface of a lake on the outbound trip, to dig below rooted plants on the inbound trip, and to pass over small crevices or uneven joints on a ramp, truck or trailer at the collection site. Embodiments of the invention may be constructed in a variety of sizes from standard size materials that are commercially available, such as aluminum, steel or plastics.
