Aquatic vegetation shredder having bow and stern mounted high speed, large chopping propellers

摘要

An aquatic shredder includes a watercraft and a pair of large, high speed propellers mounted at both the bow and stern ends of the watercraft. The propellers are configured to not only propel the watercraft through the water but also to chop vegetation at or near the water surface. Moreover, the bow propellers are similar in construction to the stern propellers so that they similarly effect comminution of the vegetation and propulsion of the watercraft. In particular, each pair of propellers extends completely across the width of the watercraft and projects laterally outward beyond the port and starboard sides of the watercraft. Each pair of propellers is preferably supported by a swingable frame that permits the user to raise and lower the propellers as desired. To enhance the cutting action of the propellers, the blades of the propellers may be provided with fore and aft extending knives.
