I have the same problem. Here's my "REDNECK" solution that works pretty well.
On the back rack of my 4-wheeler strap a long metal pole 6-8 feet in length. Tie the handle bars of a push mower to it and pull it around the edge. The long pole allows for the 4-wheeler to stay on dry ground. By pulling, it throws all the cuttings on the shore instead of the water. Works for me!
