I experienced this with the battery lawn mower I bought. Because it was electric, they could do two smaller motors and have twin blades. Sounds fancy. But I don't love it. It can't accommodate a side-chute, leaving me only with mulching and bagging. Those are fine until I leave the lawn long and then things get real slow. The twin blades also sometimes leave a little bit of uncut grass down the middle, which wouldn't happen with a single blade. This might be a product of only being 40V rather than the blade design, but it also seems to have less "suction" to pull up the grass to be cut than I've noticed in traditional gas mowers.
