Abstract
An aquatic vegetation shredder includes a double hull watercraft, with a space being defined between the hulls. The machine also includes an aquatic vegetation shredding assembly mounted to the watercraft adjacent the bow end, and a pair of propellers rotatably mounted to the watercraft adjacent the stem end. The propellers are configured to propel the watercraft through the water and draw water through the space defined between the hulls. Such a design causes the vegetation to be drawn toward the vegetation shredding assembly, while preventing the shredded vegetation from accumulating at the assembly; thereby eliminating the need for feeding devices for feeding the vegetation to the shredding assembly and discharge chutes for discharging the shredded vegetation away from the assembly. In addition, the propellers are operable to shred vegetation, thereby ensuring destruction of vegetation below the water surface and further commination of vegetation received from the shredding assembly. These features cooperatively provide a low displacement vessel that is particularly effective in shallow water environments.
