ABSTRACT:
A weed cutter for cutting weeds and other vegetation from the floor of a body of water. The underwater weed cutter includes a generally closed housing having at a front opening in the housing behind which the cutting mechanism is located. The weeds and other vegetation to be cut enter the opening wherein they are exposed to a plurality of cutting blades, each cutting blade being rotatably attached to one of two cutting mechanisms. The cutting mechanisms are driven by an electric motor which is coupled to a plurality of sprockets forming a gear box. The cutting mechanisms are routed from the rear of the housing toward to the front near the centerline where they turn approximately 90 degrees in opposite directions and proceed parallel to the opening as the cutting blades attached thereto perform the cutting operation. Ingested weed and vegetation clippings and other debris are discharged from the housing at a rear opening. A pair of rollers is rotatably attached to the bottom of the housing and a handle extends from the housing above the surface of the body of water whereby the operator can push the underwater weed cutter along the floor of the body of water. A submergible electric motor drives the cutting mechanism and is powered by a rechargeable submergible battery. A deadman switch is also provided so that the underwater weed cutter will only operate when the operator engages two levers located at the top of the handle.
