I have a decent Honda self drive mower with a bagger. The grass seems not to all go into the bagger, but leaves trails behind the mower, which I have to rake up. I have checked underneath, and all the passages are clear. Should I power wash it really good to get some of the surface crud off it? Is this normal? Is there something to set in there that I'm not setting. If I take the bag off, there is a flap that comes down, and I guess would mulch everything. But then, I think I'd just have more cut grass to rake.
