Floating aquatic vegetation is harvest from the surface of a body of water. The vegetation is chopped or shredded when floating in situ on the body of water. The vegetation is then removed from the water surface. The chopping, shredding, tearing or other action breaks down the structure of the plants or subdivides them into smaller parts. This reduces the structure of the plant and allows it to be compacted to a much higher density mass so that it can be handled more readily. The apparatus for harvesting the vegetation includes a self-propelled vessel. A shredding head is carried on the vessel for shredding the vegetation as the platform advances thereacross and removing the shredded vegetation from the surface of the body of water. The vegetation shredding means are two rotors arranged in a shallow V arrangement across the front end of the vessel, with the point of the V directed forwardly, in the direction of travel. Rotors arranged in this way assist with the positive tracking of the platform. When rotated so that the bottom of the rotor travels towards the rear, and the top towards the front, the vegetation is directed towards the center of the vessel, behind the rotors, in a windrow for subsequent pickup. The V configuration also limits dispersion of the vegetation around the ends of the rotors. The rotors are covered on the top and ends by a shroud. This assists in preventing dispersal of the rent material and serves as part of the collecting system.
