I would hope this is not off topic. But my question is very simple. When I cut grass around my yard I have some grass that is growing faster than the rest. But the only grass that is growing faster than the rest is the stuff that I did with the weed wacker. the rest done with the mower is not growing as fast. My best guess is that one does a better cut on the grass than the other. But if anybody could explain this that would be great.
Update: I use a mix of a riding lawn mower a a push mower. Both set to about 3" in height. The blades are slightly dull on the rider and the push mower itself is new. I usually never water my grass, I let the rain do that for me. I do not use any fertilizer. I am not sure about what types of grass I have. Some areas have grass that grows thing but thick, and others that grow pretty big but few blades per plant.
I use the weed wacker around fence, the mail box, under my big trailers, around the house etc. I use .065" 5-point star twisted line but will be going to .08" twisted square once the other stuff is gone. The weed wacker is not the most powerful but is loved by the owner :). It could use a cord, or battery.
