I am doing all this by hand, and it is awkward for sure. I use the pool noodle float on the rake to snare just the floating mats on the 11-inch rake tines. A full rake load is about my limit than I can effectively maneuver - maybe 35 lbs?. As the rake nears shore, I try to orient it vertically, to keep algae from falling off the tines. I then carry the rake over the yardglider and rotate so the algae slides off the tines.

Still, some algae strands remain at the shore. I pick them up by hand or just let it be. If there is still a lot of submerged algae, I take off the float from the rake and go deeper. This usually fouls the entire rake frame with algae and weeds, making it harder to slide stuff off.
