发明名称 RAKE SYSTEMS AND METHODS FOR REMOVING UNDERWATER VEGETATION
摘要 A rake system for removing underwater vegetation comprising a plate assembly, a handle assembly, and a line. The plate assembly comprises first and second engaging members each defining an engaging edge. The handle assembly is attached to the plate assembly. The line is attached to the handle assembly. During use, the user grips the handle assembly to toss the plate assembly to a first underwater location. The user then pulls the line to displace the plate assembly from the first underwater location along a harvest path. The engaging edges of the engaging members are adapted to engage the underwater vegetation to fix the underwater vegetation relative to the plate assembly such that continued pulling on the line removes the underwater vegetation in a harvest region defined by the harvest path.
