20120102904 | NON-BINDING CUTTERHEAD FOR CUTTING AQUATIC VEGETATION - A cutterhead for cutting aquatic vegetation, includes a cutterhead shroud, stationary teeth secured to the shroud, and a drum rotatably mounted within the shroud and bearing a flight of vanes cooperating with the teeth to cut vegetation. In accordance with the non-binding aspect of the cutterhead, each vane has an edge that rises gradually from a trailing end adjacent (during drum rotation) to a stationary tooth, to provide a clearance area adjacent the vane into which a respective tooth may be deflected during cutting without impinging upon an associated vane, and thus without causing binding of the cutterhead in the event of such deflection. Each vane may have a curvilinear edge extending from its cutting end to a surface of the drum at its trailing end. The edge defines a two-dimensional profile having a trailing end tangent forming an angle of not more than 70 degrees with the drum. | 05-03-2012 |
20120240543 | APPARATUS AND METHOD FOR EXTRACTING AQUATIC WEEDS - An apparatus and method for removing rooted aquatic weeds. An elongated pole includes a remotely operated arm at its distal end. The arm is movable from a disengaged position to an engaged position. The user pushes the distal end of the pole underwater, until it enters the tendrils of a target weed. The remote control is activated, deploying the arm into an engaged position, generally perpendicular to the pole. Simultaneously, the user begins to rotate the pole until resistance to further rotation is detected. This indicates that the tendrils of the weed have been engaged by the arm. Pushing and pulling forces are applied to the pole, until the user detects that the roots of the weed have been extracted from the soil. Continued rotation of the pole while pulling upwardly brings the weed to the water surface, where it may be pulled completely out of the water. | 09-27-2012 |
20130152533 | Method and Apparatus for Cutting Aquatic Vegetation - An aquatic vegetation cutter adaptable to a bow of a vessel having rotatable, cultivator-type cutter disks on converging angles along each side of the bow, and extending partially below the water line. Smaller ancillary cutter disks are mounted to the leading face of the larger cultivator-type cutter disks. The larger cutter disks and smaller ancillary cutter disks are driven using at least one drive motor, a series of drive sprockets and a connecting drive chain. | 06-20-2013 |
