Abstract
A submarine vegetation cutter is disclosed, driven by a direct current electrical motor adapted to drive two reciprocating type cutting blade assemblies which are disposed in a substantially opposed relationship relative to each other, and means for transmitting the driving force of the motor to the blade assemblies, and means for reversing the polarity of the direct current to the motor. There is also included a level switch for preventing electrical power from being conducted to the motor when the vegetation cutter is held at a more than predetermined angle from the vertical.
